TO AVOID POSSIE INJU, EXPLOSN O DEATH, PATIE SAFE HANDLING OF EFIGEANTS. SSTEM ONTAMINANTS, IMPOPE SEVIE POEDUE AND/O PHSIAL ABUSE AFFETING HEMETI OMPESSO ELETIAL TEMINALS MA AUSE DANGEOUS SSTEM VENTING. The successful development of hermetically sealed refrigeration compressors has completely sealed the compressor's moving parts and electric motor inside a common housing, minimizing refrigerant leaks and the hazards sometimes associated with moving belts, pulleys or couplings. Fundamental to the design of hermetic compressors is a method whereby electrical current is transmitted to the compressor motor through terminal conductors which pass through the compressor housing wall. These terminals are sealed in a dielectric material which insulates them from the housing and maintains the pressure tight integrity of the hermetic compressor. The terminals and their dielectric embedment are strongly constructed, but are vulnerable to careless compressor installation or maintenance procedures and equally vulnerable to internal electrical short circuits caused by excessive system contaminants. In either of these instances, an electrical short between the terminal and the compressor housing may result in the loss of integrity between the terminal and its dielectric embedment. This loss may cause the terminals to be expelled, thereby venting the vaporous and liquid contents of the compressor housing and system. A venting compressor terminal normally presents no danger to anyone, providing the terminal protective cover is properly in place. If, however, the terminal protective cover is not properly in place, a venting terminal may discharge a combination of (a) hot lubricating oil and refrigerant (b) flammable mixture (if system is contaminated with air) in a stream of spray which may be dangerous to anyone in the vicinity. Death or serious bodily injury could occur. Under no circumstances is a hermetic compressor to be electrically energized and/or operated without having the terminal protective cover properly in place. See Service Section S-7 for proper servicing. 3

64 PODUT DESIGN This section gives a basic description of cooling unit operation, its various components and their basic operation. Ensure your system is properly sized for heat gain and loss according to methods of the Air onditioning ontractors Association (AA) or equivalent. ONDENSING UNIT The condenser air is pulled through the condenser coil by a direct drive propeller fan. This condenser air is then discharged out of the top of the cabinet. These units are designed for free air discharge, so no additional resistance, like duct work, shall be attached. The suction and liquid line connections on present models are of the sweat type for field piping with refrigerant type copper. Front seating valves are factory installed to accept the field run copper. The total refrigerant charge for a normal installation is factory installed in the condensing unit. GSX, GSZ, ASX, ASZ, SSX, SSZ, DSX, DSZ, VSX, and VSZ models are available in / through 5 ton sizes and use -40A refrigerant. They are designed for 08/30 volt single phase applications. GSX/GSZ *****3 models are available in 3, 4, and 5 ton sizes and use -40A refrigerant. They are designed for 08/30 volt 3- phase applications. ASX, ASZ, DSX and DSZ -40A model units use the opeland Scroll "Ultratech" Series compressors which are specifically designed for -40A refrigerant. These units also have opeland omfortalert diagnostics. GSX, GSZ, SSX, SSZ, VSX, and VSZ -40A model units, except for GSX308*, VSX308B*, VSX304E*, VSX304B*, and VSX3048B*, use the opeland Scroll "Ultratech" Series compressors which are specifically designed for -40A refrigerant. There are a number of design characteristics which are different from the traditional reciprocating and/or scroll compressors. "Ultractech" Series scroll compressors will not have a discharge thermostat. Some of the early model scroll compressors required discharge thermostat. "Ultratech" Series scroll compressors use "POE" or polyolester oil which is NOT compatible with mineral oil based lubricants like 3GS. "POE" oil must be used if additional oil is required. The MB blower cabinet uses a PS motor. It is approved for applications with cooling coils of up to 0.5 inches W.. external static pressure. The MB/MBE blower cabinets with proper coil matches can be positioned for upflow, counterflow, horizontal right or horizontal left operation. All units are constructed with -4. insulation. In areas of extreme humidity (greater than 80% consistently), insulate the exterior of the blower with insulation having a vapor barrier equivalent to ductwork insulation, providing local codes permit. The AUF, APF and APT coils are designed for upflow and counterflow applications. The AF and HPF coils are designed for horizontal applications. A*F, ASPF, ASUF, ASPT Multi-Position Air Handler These one-piece multi-position air handlers are used with - 40A and are available in to 5 ton sizes with optional 3 kw to 5kW electric heat kits available for field installation. The A*F unit s blower design includes a PS motor and is compatible with heat pumps and cooling applications. ASUF and ASPT units use an EEM blower motor and are compatible with heat pumps and cooling applications. This appliance can be installed in the vertical or left horizontal position without modification. The horizontal right and downflow positions require product modification. This product is designed for zero inches (0 inches) clearance; however, adequate access for service or replacement must be considered without removing permanent structure. This unit can be installed on a platform when deemed necessary. In an attic installation a secondary drain pan must be provided by the installer and placed under the entire unit with a separate drain line properly sloped and terminated in an area visible to the owner. This secondary drain pan is required in the event that there is a leak or main drain blockage. losed cell insulation should be applied to the drain lines in unconditioned spaces where sweating may occur. NOTE: Single piece air handlers are factory-sealed to achieve a % or less leakage rate at.0" water gauge external duct static pressure. OILS AND OWE OILS MB/MBE blower cabinets are designed to be used as a two-piece blower and coil combination. MB/MBE/MBV blower sections can be attached to cased evaporator coil. This two-piece arrangement allows for a variety of mix-matching possibilities providing greater flexibility. The MBE/MBV blower cabinets use a variable speed motor that maintains a constant airflow with a higher duct static. MBE blower cabinests are approved for applications with cooling coils of up to 0.8 inches W.. external static pressure. The MBE models includes a feature that allows airflow to be changed by +0% or -5%. The MBV models allow airflow trimming of +/- 0%. 64

65 PODUT DESIGN The ASX [6 & 8], ASZ [6 & 8], DSX[6 & 8] and DSZ [6 & 8] series split system units use a two-stage scroll compressor. The two-step modulator has an internal unloading mechanism that opens a bypass port in the first compression pocket, effectively reducing the displacement of the scroll. The opening and closing of the bypass port is controlled by an internal electrically operated solenoid. The ZPS/ZS two-step modulated scroll uses a single step of unloading to go from full capacity to approximately 67% capacity. A single speed, high efficiency motor continues to run while the scroll modulates between the two capacity steps. FIGUE A As this motion occurs, the pockets between the two forms are slowly pushed to the center of the two scrolls while simultaneously being reduced in volume. When the pocket reaches the center of the scroll form, the gas, which is now at a high pressure, is discharged out of a port located at the center. During compression, several pockets are being compressed simultaneously, resulting in a very smooth process. Both the suction process (outer portion of the scroll members) and the discharge process (inner portion) are continuous. Some design characteristics of the ompliant Scroll compressor are: ompliant Scroll compressors are more tolerant of liquid refrigerant. NOTE: Even though the compressor section of a Scroll compressor is more tolerant of liquid refrigerant, continued floodback or flooded start conditions may wash oil from the bearing surfaces causing premature bearing failure. "Ultratech" Series scroll compressors use "POE" or polyolester oil which is NOT compatible with mineral oil based lubricants like 3GS. "POE" oil must be used if additional oil is required. ompliant scroll compressors perform "quiet" shutdowns that allow the compressor to restart immediately without the need for a time delay. This compressor will restart even if the system has not equalized. NOTE: Operating pressures and amp draws may differ from standard reciprocating compressors. This information can be found in the unit's Technical Information Manual. A scroll is an involute spiral which, when matched with a mating scroll form as shown, generates a series of crescent shaped gas pockets between the two members. During compression, one scroll remains stationary (fixed scroll) while the other form (orbiting scroll) is allowed to orbit (but not rotate) around the first form. 65

66 PODUT DESIGN APAIT ONTOL - LEGA MODELS During the compression process, there are several pockets within the scroll that are compressing gas. Modulation is achieved by venting a portion of the gas in the first suction pocket back to the low side of the compressor thereby reducing the effective displacement of the compressor. See Figure A. Full capacity is achieved by blocking these vents, increasing the displacement to 00%. A solenoid in the compressor, controlled by an external 4- volt ac signal, moves the slider ring that covers and uncovers these vents. The vent covers are arranged in such a manner that the compressor operates somewhere around 67% capacity when the solenoid is not energized and 00% capacity when the solenoid is energized. The loading and unloading of the two step scroll is done on the fly without shutting off the motor between steps. See Figure B below. The unloaded mode default was chosen for two reasons: Molded Plug w/ ectifier 4 Vac S Internal Unloader oil Line un apacitor Line FIGUE B. It is expected that the majority of run hours will be in the low capacity, unloaded mode.. It allows a simple two-stage thermostat to control capacity through the second stage in both cooling and possibly heating if desired. UNLOADE SOLENOID A nominal 4-volt direct current coil activates the internal unloader solenoid. The input control circuit voltage must be 8 to 8 volt ac. The coil power requirement is 0 VA. The external electrical connection is made with a molded plug assembly. This plug is connected to the omfort Alert or oresense Module (dependent upon which module you are using) which contains a full wave rectifier to supply direct current to the unloader coil. OOLING The refrigerant used in the system is -40A. It is a clear, colorless, non-toxic and non-irritating liquid. -40A is a 50:50 blend of -3 and -5. The boiling point at atmospheric pressure is -6.9 F. A few of the important principles that make the refrigeration cycle possible are: heat always flows from a warmer to a cooler body. Under lower pressure, a refrigerant will absorb heat and vaporize at a low temperature. The vapors may be drawn off and condensed at a higher pressure and temperature to be used again. The indoor evaporator coil functions to cool and dehumidify the air conditioned spaces through the evaporative process taking place within the coil tubes. NOTE: The pressures and temperatures shown in the refrigerant cycle illustrations on the following pages are for demonstration purposes only. Actual temperatures and pressures are to be obtained from the "Expanded Performance hart". Liquid refrigerant at condensing pressure and temperatures, (70 psig and F), leaves the outdoor condensing coil through the drier and is metered into the indoor coil through the metering device. As the cool, low pressure, saturated refrigerant enters the tubes of the indoor coil, a portion of the liquid immediately vaporizes. It continues to soak up heat and vaporizes as it proceeds through the coil, cooling the indoor coil down to about 48 F. Heat is continually being transferred to the cool fins and tubes of the indoor evaporator coil by the warm system air. This warming process causes the refrigerant to boil. The heat removed from the air is carried off by the vapor. As the vapor passes through the last tubes of the coil, it becomes superheated. That is, it absorbs more heat than is necessary to vaporize it. This is assurance that only dry gas will reach the compressor. Liquid reaching the compressor can weaken or break compressor valves. The compressor increases the pressure of the gas, thus adding more heat, and discharges hot, high pressure superheated gas into the outdoor condenser coil. In the condenser coil, the hot refrigerant gas, being warmer than the outdoor air, first loses its superheat by heat transferred from the gas through the tubes and fins of the coil. The refrigerant now becomes saturated, part liquid, part vapor and then continues to give up heat until it condenses to a liquid alone. Once the vapor is fully liquefied, it continues to give up heat which subcools the liquid, and it is ready to repeat the cycle. 66

67 SSTEM OPEATN HEATING The heating portion of the refrigeration cycle is similar to the cooling cycle. By energizing the reversing valve solenoid coil, the flow of the refrigerant is reversed. The indoor coil now becomes the condenser coil, and the outdoor coil becomes the evaporator coil. The check valve at the indoor coil will open by the flow of refrigerant letting the now condensed liquid refrigerant bypass the indoor expansion device. The check valve at the outdoor coil will be forced closed by the refrigerant flow, thereby utilizing the outdoor expansion device. The restrictor orifice used with the A*F, HPF and H**FB coils will be forced onto a seat when running in the cooling cycle, only allowing liquid refrigerant to pass through the orifice opening. In the heating cycle, it will be forced off the seat allowing liquid to flow around the restrictor. A check valve is not required in this circuit. OOLING E For legacy room thermostat: When the room thermostat calls for cool, the contacts of the room thermostat close making terminals to & G (if thermostat calls for low stage cool), or to, & G (if thermostat calls for high stage cool), the low voltage circuit of the transformer is completed. urrent now flows through the magnetic holding coils of the compressor contactor () and fan relay (F). If thermostat calls for high stage cool, the microprocessor on the U board will also energize the compressor high stage solenoid to run the compressor at full capacity. This draws in the normally open contact, starting the compressor and condenser fan motors in either low or high stage depending on the thermostat s demand. At the same time, contacts F close, starting the indoor fan motor. When the thermostat is satisfied, it opens its contacts, breaking the low voltage circuit, causing the compressor contactor and indoor fan relay to open, shutting down the system. If the room thermostat fan selector switch should be set on the on position, then the indoor blower would run continuously rather than cycling with the compressor. GSZ, ASZ, SSZ, DSZ, and VSZ models energize the reversing valve thorough the "O" circuit in the room thermostat. Therefore, the reversing valve remains energized as long as the thermostat subbase is in the cooling position. The only exception to this is during defrost. For heat pumps, during cooling cycle the reversing valve is energized as the room thermostat closes O terminal to and the microprocessor on the U board responds to such a condition by energizing the solenoid coil on the reversing valve. DEFOST E The defrosting of the outdoor coil is jointly controlled by the defrost control board and the defrost thermostat. Solid State Defrost ontrol During operation the power to the circuit board is controlled by a temperature sensor, which is clamped to a return bend (3/8" coils) or a feeder tube (5 mm coils) entering the outdoor coil. Defrost timing periods of 30, 60, or 90 minutes may be selected by connecting the circuit board jumper to 30, 60, or 90 respectively. Accumulation of time for the timing period selected starts when the sensor closes (approximately 3 F), and when the room thermostat calls for heat. At the end of the timing period, the unit s defrost cycle will be initiated provided the sensor remains closed. When the sensor opens (approximately 75 F), the defrost cycle is terminated and the timing period is reset. If the defrost cycle is not terminated due to the sensor temperature, a ten minute override interrupts the unit s defrost period. The new upgraded defrost control has a minute override interrupt. HEATING E The reversing valve on the GSZ, SSZ, ASZ and DSZ models is energized in the cooling cycle through the "O" terminal on the room thermostat. These models have a 4 volt reversing valve coil. When the thermostat selector switch is set in the cooling position, the "O" terminal on the thermostat is energized all the time. are must be taken when selecting a room thermostat. efer to the installation instructions shipped with the product for approved thermostats. When the room thermostat calls for heat, the contacts of the room thermostat close making terminals to & G, the low voltage circuit of the transformer is completed. urrent now flows through the magnetic holding coils of the compressor contactor () and fan relay (F). This draws in the normally open contact, starting the compressor condenser fan motors. At the same time, contacts F close, starting the indoor fan motor. When the thermostat is satisfied, it opens its contacts, breaking the low voltage circuit, causing the compressor contactor and indoor fan relay to open, shutting down the system. If the room thermostat fan selector switch should be set to the on position, then the indoor blower would run continuously rather than cycling with the compressor. When the thermostat is satisfied, appropriate commands are sent to the U control. The compressor relay and outdoor fan relay is de-energized. The compressor high stage solenoid is de-energized if it was energized. The U control sends an appropriate command to the indoor unit to de-energize the indoor blower motor. 67

ESTITO OIFIE ASSEM IN OOLING OPEATN ESTITO OIFIE ASSEM IN HEATING OPEATN In the cooling mode, the orifice is pushed into its seat, forcing refrigerant to flow through the metered hole in the center of the orifice. In the heating mode, the orifice moves back off its seat, allowing refrigerant to flow unmetered around the outside of the orifice. 69

70 SSTEM OPEATN AFE8-60A ONTOL BOA DESIPTN The AFE8 control is designed for use in heat pump applications where the indoor coil is located above/downstream of a gas or fossil fuel furnace. It will operate with single and two stage heat pumps and single and two stage furnaces. The AFE8 control will turn the heat pump unit off when the furnace is turned on. An antishort cycle feature is also incorporated which initiates a 3 minute timed off delay when the compressor goes off. On initial power up or loss and restoration of power, this 3 minute timed off delay will be initiated. The compressor won t be allowed to restart until the 3 minute off delay has expired. Also included is a 5 second de-bounce feature on the, E, W and O thermostat inputs. These thermostat inputs must be present for 5 seconds before the AFE8 control will respond to it. An optional outdoor thermostat, OT8-60A, can be used with the AFE8 to switch from heat pump operation to furnace operation below a specific ambient temperature setting, i.e. break even temperature during heating. When used in this manner, the heat demand is switched to the W input to the furnace by the outdoor thermostat and the furnace is used to satisfy the first stage heat demand. On some controls, if the outdoor thermostat fails closed in this position during the heating season, it will turn on the furnace during the cooling season on a cooling demand. In this situation, the furnace produces heat and increases the indoor temperature thereby never satisfying the cooling demand. The furnace will continue to operate and can only be stopped by switching the thermostat to the off position or removing power to the unit and then replacing the outdoor thermostat. When the AFE8 receives a and O input from the indoor thermostat, it recognizes this as a cooling demand in the cooling mode. If the outdoor thermostat is stuck in the closed position switching the demand to the W furnace input during the cooling mode as described above, the AFE8 won t allow the furnace to operate. The outdoor thermostat will have to be replaced to restore the unit to normal operation. HIGH VOLTAGE! Disconnect ALL power before servicing or installing. Multiple power sources may be present.

S-0 MB/A*F ELETONI OWE TIME DELA ELA The MB/A*F contains an Electronic Blower Time Delay elay board, B This board provides on/off time delays for the blower motor in cooling and heat pump heating demands when G is energized. During a cooling or heat pump heating demand, 4Vac is supplied to terminal G of the EBTD to turn on the blower motor. The EBTD initiates a 7 second delay on and then energizes it s onboard relay. The relay on the EBTD board closes it s normally open contacts and supplies power to the blower motor. When the G input is removed, the EBTD initiates a 65 second delay off. When the 65 seconds delay expires the onboard relay is de-energized and it s contacts open and remove power from the blower motor. During an electric heat only demand, W is energized but G is not. The blower motor is connected to the normally closed contacts of the relay on the EBTD board. The other side of this set of contacts is connected to the heat sequencer on the heater assembly that provides power to the first heater element. When W is energized, the sequencer will close it s contacts within 0 to 0 seconds to supply power to the first heater element and to the blower motor through the normally closed contacts on the relay on the EBTD. When the W demand is removed, the sequencer opens it contacts within 30 to 70 seconds and removes power from the heater element and the blower motor. The EBTD also contains a speedup terminal to reduce the delays during troubleshooting of the unit. When this terminal is shorted to the common terminal,, on the EBTD board, the delay ON time is reduced to 3 seconds and the delay OFF time is reduced to 5 second. Two additional terminals, M and M, are on the EBTD board. These terminals are used to connect the unused leads from the blower motor and have no affect on the board s operation.

83 SEVIING S-5 HEKING APAITO APAITO, UN A run capacitor is wired across the auxiliary and main windings of a single phase permanent split capacitor motor. The capacitors primary function is to reduce the line current while greatly improving the torque characteristics of a motor. This is accomplished by using the 90 phase relationship between the capacitor current and voltage in conjunction with the motor windings, so that the motor will give two phase operation when connected to a single phase circuit. The capacitor also reduces the line current to the motor by improving the power factor. The line side of this capacitor is marked with "OM" and is wired to the line side of the circuit. APAITO, STAT SOLL OMPESSO MODELS In most cases hard start components are not required on Scroll compressor equipped units due to a non-replaceable check valve located in the discharge line of the compressor. However, in installations that encounter low lock rotor voltage, a hard start kit can improve starting characteristics and reduce light dimming within the home. Only hard start kits approved by Amana brand or opeland should be used. "Kick Start" and/or "Super Boost" kits are not approved start assist devices. The discharge check valve closes off high side pressure to the compressor after shut down allowing equalization through the scroll flanks. Equalization requires only about / second. To prevent the compressor from short cycling, a Time Delay elay (ycle Protector) has been added to the low voltabe circuit. S-5AESISTANE HEK USING A DIGITAL MULTI- METE HIGH VOLTAGE!

84 SEVIING S-6AHEKING FAN AND OWE MOTO WINDINGS (PS MOTOS) The auto reset fan motor overload is designed to protect the motor against high temperature and high amperage conditions by breaking the common circuit within the motor, similar to the compressor internal overload. However, heat generated within the motor is faster to dissipate than the compressor, allow at least 45 minutes for the overload to reset, then retest. HIGH VOLTAGE!

S-6B HEKING FAN AND OWE MOTO (EM MOTOS) An EM is an Electronically ommutated Motor which offers many significant advantages over PS motors. The EM has near zero rotor loss, synchronous machine operation, variable speed, low noise, and programmable air flow. Because of the sophisticated electronics within the EM motor, some technicians are intimated by the EM motor; however, these fears are unfounded. GE offers two EM motor testers, and with a VOM meter, one can easily perform basic troubleshooting on EM motors. An EM motor requires power (line voltage) and a signal (4 volts) to operate. The EM motor stator contains permanent magnet. As a result, the shaft feels "rough" when turned by hand. This is a characteristic of the motor, not an indication of defective bearings.

Disconnect the 5-pin and the 6-pin connectors from the EM power head.. emove the screws securing the EM power head and separate it from the motor. 3. Disconnect the 3-pin motor connector from the power head and lay it aside. 4. Using an ohmmeter, check the motor windings for continuity to ground (pins to motor shell). If the ohmmeter indicates continuity to ground, the motor is defective and must be replaced. 5. Using an ohmmeter, check the windings for continuity (pin to pin). If no continuity is indicated, the thermal limit (over load) device may be open. Allow motor to cool and retest. 3-pin motor connector 6-pin connector 5-pin connector For most applications, the settings are to be changed according to the electric heat size and the outdoor unit selection. The MBE/AEPF products use a General Electric EM TM motor. This motor provides many features not available on the traditional PS motor. These features include: Improved Efficiency onstant FM Soft Start and Stop Improved Humidity ontrol MOTO SPEED ADJUSTMENT Each EM blower motor has been preprogrammed for operation at 4 distinct airflow levels when operating in ooling/heat Pump mode or Electric Heat mode. These 4 distinct levels may also be adjusted slightly lower or higher if desired. The adjustment between levels and the trim adjustments are made by changing the dipswitch(s) either to an "OFF" or "ON" position. DIPSWITH FUNTNS The MBE / AEPF air handler motors have an electronic control that contains an eight (8) position dip switch. The function of these dipswitches are shown in Table.

If the compressor terminal POTETIVE OVE and gasket (if required) are not properly in place and secured, there is a remote possibility if a terminal vents, that the vaporous and liquid discharge can be ignited, spouting flames several feet, causing potentially severe or fatal injury to anyone in its path. This discharge can be ignited external to the compressor if the terminal cover is not properly in place and if the discharge impinges on a sufficient heat source. Ignition of the discharge can also occur at the venting terminal or inside the compressor, if there is sufficient contaminant air present in the system and an electrical arc occurs as the terminal vents. Ignition cannot occur at the venting terminal without the presence of contaminant air, and cannot occur externally from the venting terminal without the presence of an external ignition source. Therefore, proper evacuation of a hermetic system is essential at the time of manufacture and during servicing. To reduce the possibility of external ignition, all open flame, electrical power, and other heat sources should be extinguished or turned off prior to servicing a system.. eplace the motor and reinstall blower and control box.. econnect power and test operation. 9

92 SEVIING S-7AESISTANE TEST Each compressor is equipped with an internal overload. The line break internal overload senses both motor amperage and winding temperature. High motor temperature or amperage heats the disc causing it to open, breaking the common circuit within the compressor on single phase units. Heat generated within the compressor shell, usually due to recycling of the motor, high amperage or insufficient gas to cool the motor, is slow to dissipate. Allow at least three to four hours for it to cool and reset, then retest. Fuse, circuit breaker, ground fault protective device, etc. has not tripped - HIGH VOLTAGE! Disconnect ALL power before servicing or installing. Multiple power sources may be present. Failure to do so may cause property damage, personal injury or death.. emove the leads from the compressor terminals. WANING Hermetic compressor electrical terminal venting can be dangerous. When insulating material which supports a hermetic compressor or electrical terminal suddenly disintegrates due to physical abuse or as a result of an electrical short between the terminal and the compressor housing, the terminal may be expelled, venting the vapor and liquid contents of the compressor housing and system. S-7B GOUND TEST If fuse, circuit breaker, ground fault protective device, etc., has tripped, this is a strong indication that an electrical problem exists and must be found and corrected. The circuit protective device rating must be checked, and its maximum rating should coincide with that marked on the equipment nameplate. With the terminal protective cover in place, it is acceptable to replace the fuse or reset the circuit breaker ONE TIME ONL to see if it was just a nuisance opening. If it opens again, DO NOT continue to reset. Disconnect all power to unit, making sure that all power legs are open.. DO NOT remove protective terminal cover. Disconnect the three leads going to the compressor terminals at the nearest point to the compressor.. Identify the leads and using an ohmmeter on the x 0,000 scale or the highest resistance scale on your ohmmeter check the resistance between each of the three leads separately to ground (such as an unpainted tube on the compressor). 3. If a ground is indicated, then carefully remove the compressor terminal protective cover and inspect for loose leads or insulation breaks in the lead wires. 4. If no visual problems indicated, carefully remove the leads at the compressor terminals. 5. arefully retest for ground, directly between compressor terminals and ground. 6. If ground is indicated, replace the compressor. The resistance reading should be infinity. If there is any reading on meter, there is some continuity to ground and compressor should be considered defective.. Using an ohmmeter, test continuity between terminals S-, -, and -S, on single phase units or terminals T, T and T3, on 3 phase units. OHMMETE OHMMETE S OMP WANING Damage can occur to the glass embedded terminals if the leads are not properly removed. This can result in terminal and hot oil discharging. TESTING OMPESSO WINDINGS If either winding does not test continuous, replace the compressor. NOTE: If an open compressor is indicated, allow ample time for the internal overload to reset before replacing compressor. S-7 UNLOADE TEST POEDUE A nominal 4-volt direct current coil activates the internal unloader solenoid. The input control circuit voltage must be 8 to 8 volt ac. The coil power requirement is 0 VA. The external electrical connection is made with a molded plug assembly. This plug contains a full wave rectifier to supply direct current to the unloader coil. 9

93 SEVIING HIGH VOLTAGE! Disconnect ALL power before servicing or installing. Multiple power sources may be present. Failure to do so may cause property damage, personal injury or death. UNLOADE SOLENOID (Molded Plug) Unloader Test Procedure If it is suspected that the unloader is not working, the following methods may be used to verify operation.. Operate the system and measure compressor current. ycle the unloader ON and OFF at 0 second intervals. The compressor amperage should go up or down at least 5 percent.. If step one does not give the expected results, shut unit off. Apply 8 to 8 volt ac to the unloader molded plug leads and listen for a click as the solenoid pulls in. emove power and listen for another click as the unloader returns to its original position. 3. If clicks can t be heard, shut off power and remove the control circuit molded plug from the compressor and measure the unloader coil resistance. The resistance should be 3 to 60 ohms, depending on compressor temperature. 4. Next check the molded plug. A. Voltage check: Apply control voltage to the plug wires (8 to 8 volt ac). The measured dc voltage at the female connectors in the plug should be around 5 to 7 vdc. B. esistance check: Measure the resistance from the end of one molded plug lead to either of the two female connectors in the plug. One of the connectors should read close to zero ohms while the other should read infinity. epeat with other wire. The same female connector as before should read zero while the other connector again reads infinity. everse polarity on the ohmmeter leads and repeat. The female connector that read infinity previously should now read close to zero ohms.. eplace plug if either of these test methods doesn t show the desired results. S-7DOPEATN TEST If the voltage, capacitor, overload and motor winding test fail to show the cause for failure:. emove unit wiring from disconnect switch and wire a test cord to the disconnect switch. NOTE: The wire size of the test cord must equal the line wire size and the fuse must be of the proper size and type.. With the protective terminal cover in place, use the three leads to the compressor terminals that were disconnected at the nearest point to the compressor and connect the common, start and run clips to the respective leads. 3. onnect good capacitors of the right MFD and voltage rating into the circuit as shown. 4. With power ON, close the switch. WANING Line Voltage now present. A. If the compressor starts and continues to run, the cause for failure is somewhere else in the system. B.

This is normal and does not harm the compressor.. Install gauges and verify that the suction pressure drops while the discharge pressure increases.. Listen for normal compressor sound levels. everse rotation results in elevated or unusual sound levels. 3. everse rotation will result in substantially reduced amp draw from tabulated values. To correct improper rotation, switch any two power supply leads at the outdoor unit contactor. 93

94 SEVIING The 3-phase scroll compressors are direction of rotation sensitive. They will rotate in either direction depending on the phasing of the power. There is no negative impact on durability caused by operating 3-phase compressors in reversed rotation. The compressor's internal protector will trip, de-energizing the compressor. ontinued operation of 3-phase scroll compressors with the rotation reversed will contribute to compressor failure. All 3-phase scroll compressors should be checked for correct phase rotation. S-8 TESTING ANKASE HEATE (OPTNAL ITEM) The crankcase heater must be energized a minimum of four (4) hours before the condensing unit is operated. rankcase heaters are used to prevent migration or accumulation of refrigerant in the compressor crankcase during the off cycles and prevents liquid slugging or oil pumping on start up. A crankcase heater will not prevent compressor damage due to a floodback or over charge condition. WANING Disconnect ALL power before servicing.. Disconnect the heater lead in wires.. Using an ohmmeter, check heater continuity - should test continuous. If not, replace. NOTE: The positive temperature coefficient crankcase heater is a 40 watt 65 voltage heater. The cool resistance of the heater will be approximately 800 ohms. The resistance will become greater as the temperature of the compressor shell increases. S- HEKING EVESING VALVE AND SOLENOID Occasionally the reversing valve may stick in the heating or cooling position or in the mid-position. When stuck in the mid-position, part of the discharge gas from the compressor is directed back to the suction side, resulting in excessively high suction pressure. An increase in the suction line temperature through the reversing valve can also be measured. heck operation of the valve by starting the system and switching the operation from OOLING to HEATING cycle. If the valve fails to change its position, test the voltage (4V) at the valve coil terminals, while the system is on the OOLING cycle. If no voltage is registered at the coil terminals, check the operation of the thermostat and the continuity of the connecting wiring from the "O" terminal of the thermostat to the unit. S-4 TESTING DEFOST ONTOL To check the defrost control for proper sequencing, proceed as follows: With power ON; unit not running.. Jumper defrost thermostat by placing a jumper wire across the terminals "DFT" and ""/"-DFT" at defrost control board.. onnect jumper across test pins on defrost control board. 3. Set thermostat to call for heating. System should go into defrost within seconds. 4. Immediately remove jumper from test pins. 5. Using VOM check for voltage across terminals " & O". Meter should read 4 volts. 6. Using VOM check for voltage across fan terminals DF and DF on the board. ou should read line voltage (08-30 VA) indicating the relay is open in the defrost mode. 7. Using VOM check for voltage across "W"/"W" & "" terminals on the board. ou should read 4 volts. 8. If not as above, replace control board. 9.

At the same time, if the heater assembly contains a second heater element, H will contain a second set of contacts, M3 and M4, which will close to turn on heater element #. NOTE: If more than two heater elements are on the heater assembly, it will contain a second heat sequencer, H,which will control the 3 rd and 4 th heater elements if available. If the first stage heat demand, W cannot be satisfied by the heat pump, the temperature indoors will continue to drop. The room thermostat will then energize W and 4Vac will be supplied to H on the heater assembly. When the W demand is satisfied, the room thermostat will remove the 4Vac from H. The contacts on H will open between 30 to 70 seconds and heater elements #3 and #4 will be turned off.

As long as the thermostat is set for heating, the reversing valve will be in the de-energized position for heating except during a defrost cycle. Some installations may use one or more outdoor thermostats to restrict the amount of electric heat that is available above a preset ambient temperature. Use of optional controls such as these can change the operation of the electric heaters during the heating mode. This sequenceof operation does not cover those applications. 4. On a demand for first stage heat with heat pump units, the room thermostat energizes G and and 4Vac is supplied to at the heat pump unit and the G terminal on the EBTD board. The heat pump is turned on in the heating mode and the blower motor starts after a 7 second on delay. 4. If the first stage heat demand cannot be satisfied by the heat pump, the temperature indoors will continue to drop. The room thermostat will then energize terminal W for second stage heat and 4Vac will be supplied to heat sequencer H on the heater assembly. 4.3 H contacts M and M will close will close within 0 to 0 seconds and turn on heater element #. At the same time, if the heater assembly contains a second heater element, H will contain a second set of contacts, M3 and M4, which will close and turn on heater element #. The blower motor is already on as a result of terminal G on the EBTD board being energized for the first stage heat demand. NOTE: If more than two heater elements are on the heater assembly, it will contain a second heat sequencer, H, which will control the 3 rd and 4 th heater elements if available. If the second stage heat demand, W cannot be satisfied by the heat pump, the temperature indoors will continue to drop. The room thermostat will then energize W3 and 4Vac will be supplied to H on the heater assembly. When the W3 demand is satisfied, the room thermostat will remove the 4Vac from H. The contacts on H will open between 30 to 70 seconds and heater elements #3 and #4 will be turned off. On most digital/ electronic thermostats, W3 will remain energized until the first stage heat demand is satisfied and then the G,, W and W3 demands will be removed. 4.4 As the temperature indoors increase, it will reach a point where the second stage heat demand, W, is satisfied. When this happens, the room thermostat will remove the 4Vac from the coil of H. The contacts on H will open between 30 to 70 seconds and turn off both heater element(s). The heat pump remains on along with the blower motor because the demand for first stage heat will still be present. 4.5 When the first stage heat demand is satisfied, the room thermostat will remove the 4Vac from G and.

96 SEVIING 5.0 Defrost Operation On heat pump units, when the room thermostat is set to the heating mode, the reversing valve is not energized. As long as the thermostat is set for heating, the reversing valve will be in the de-energized position for heating except during a defrost cycle. 5. The heat pump will be on and operating in the heating mode as described the Heating Operation in section The defrost control in the heat pump unit checks to seeif a defrost is needed every 30, 60 or 90 minutes of heat pump operation depending on the selectable setting by monitoring the state of the defrost thermostat attached to the outdoor coil. 5.3 If the temperature of the outdoor coil is low enough to cause the defrost thermostat to be closed when the defrost board checks it, the board will initiate a defrost cycle. 5.4 When a defrost cycle is initiated, the contacts of the HVD relay on the defrost board open and turns off the outdoor fan. The contacts of the LVD relay on the defrost board closes and supplies 4Vac to O and W. The reversing valve is energized and the contactson H close and turns on the electric heater(s). The unit will continue to run in this mode until the defrost cycle is completed. a.for models with defrost control PBDM33 or PBDM60, a 30 second compressor delay at defrost initiation/termination is optional. As shipped from the factory, the control is set for the delay ( DL ), which will turn the compressor off for 30 seconds while the reversing valve shifts to/from the cooling mode position. To bypass the delay, which typically reduces sound levels during defrost mode, change the pin settings from DL to NOM. 5.5 When the temperature of the outdoor coil rises high enough to causes the defrost thermostat to open, the defrost cycle will be terminated. If at the end of the programmed 0 minute override time the defrost thermostat is still closed, the defrost board will automatically terminate the defrost cycle. 5.6 When the defrost cycle is terminated, the contacts of the HVD relay will close to start the outdoor fan and the contacts of the LVD relay will open and turn off the reversing valve and electric heater(s). The unit will now be back in a normal heating mode with a heat pump demand for heating as described in the Heating Operation in section 4. See section 5.4a.

When brazing, sweep the tubing with dry nitrogen to prevent the formation of oxides on the inside surfaces. 6. omplete any repair by replacing the liquid line drier in the system, evacuate and charge. BAZING MATEIALS IMPOTANT NOTE: Torch heat required to braze tubes of various sizes is proportional to the size of the tube. Tubes of smaller size require less heat to bring the tube to brazing temperature before adding brazing alloy. Applying too much heat to any tube can melt the tube. Service personnel must use the appropriate heat level for the size of the tube being brazed. WANING To avoid possible explosion, the line from the nitrogen cylinder must include a pressure regulator and a pressure relief valve. The pressure relief valve must be set to open at no more than 50 psig. Pressure test the system using dry nitrogen and soapy water to locate leaks. If you wish to use a leak detector, charge the system to 0 psi using the appropriate refrigerant then use nitrogen to finish charging the system to working pressure, then apply the detector to suspect areas. If leaks are found, repair them. After repair, repeat the pressure test. If no leaks exist, proceed to system evacuation. S-0 EVAUATN WANING EFIGEANT UNDE PESSUE!

103 SEVIING This is the most important part of the entire service procedure. The life and efficiency of the equipment is dependent upon the thoroughness exercised by the serviceman when evacuating air (non-condensables) and moisture from the system. Air in a system causes high condensing temperature and pressure, resulting in increased power input and reduced performance. Moisture chemically reacts with the refrigerant oil to form corrosive acids. These acids attack motor windings and parts, causing breakdown. The equipment required to thoroughly evacuate the system is a high vacuum pump, capable of producing a vacuum equivalent to 50 microns or less and a vacuum gauge to give a true reading of the vacuum in the system. NOTE: Never use the Scroll compressor as a vacuum pump or run when under a high vacuum. Motor damage could occur. ondensing unit liquid and suction valves are closed to contain the charge within the unit. The unit is shipped with the valve stems closed and caps installed. Do not open valves until the system is evacuated.. onnect the vacuum pump with 50 micron capability to the service valves.. Evacuate the system to 50 microns or less using suction and liquid service valves. Using both valves is necessary as some compressors create a mechanical seal separating the sides of the system. 3. lose pump valve and hold vacuum for 0 minutes. Typically pressure will rise during this period. 4. If the pressure rises to 000 microns or less and remains steady the system is considered leak free; proceed to startup. 5. If pressure rises above 000 microns but holds steady below 000 microns, moisture and/or non-condensibles may be present or the system may have a small leak. 6. eturn to step : If the same result is encountered check for leaks as previously indicated and repair as necessary then repeat evacuation. 7.

There is commercially available restriction devices that fit into the system charging hose set to accomplish this. DO NOT charge liquid 40A into the compressor. NOTE: Power must be supplied to the 8 SEE outdoor units containing EM motors before the power is applied to the indoor unit. Sending a low voltage signal without high voltage power present at the outdoor unit can cause malfunction of the control module on the EM motor. Adequate refrigerant charge for the matching evaporator coil or air handler and 5 feet of line set is supplied with the condensing unit. If using evaporator coils or air handlers other than HSVT coil it may be necessary to add or remove refrigerant to attain proper charge. If line set exceeds 5 feet in length, refrigerant should be added at.6 ounces per foot of liquid line. NOTE: The outdoor temperature should be 60 F or higher when charging the unit.harge should always be checked using subcooling when using TXV equipped indoor coil to verify proper charge. Open the suction service valve first! If the liquid service valve is opened first, oil from the compressor may be drawn into the indoor coil TXV, restricting refrigerant flow and affecting operation of the system. When opening valves with retainers, open each valve only until the top of the stem is /8" from the retainer. To avoid loss of refrigerant, DO NOT apply pressure to the retainer. When opening valves without a retainer remove service valve cap and insert a hex wrench into the valve stem and back out the stem by turning the hex wrench counterclockwise. Open the valve until it contacts the rolled lip of the valve body. NOTE: These are not back-seating valves. It is not necessary to force the stem tightly against the rolled lip. After the refrigerant charge has bled into the system, open the liquid service valve. The service valve cap is the secondary seal for the valve and must be properly tightened to prevent leaks. Make sure cap is clean and apply refrigerant oil to threads and sealing surface on inside of cap. Tighten cap finger-tight and then tighten additional /6 of a turn ( wrench flat) to properly seat the sealing surfaces. EXPANSN VALVE SSTEM NOTE: Units matched with indoor coils equipped with nonadjustable TXV should be charged by subcooling only. NOTE: The TXV should NOT be adjusted at light load conditions 55º to 60ºF. Use the following guidelines and methods to check unit operation and ensure that the refrigerant charge is within limits. harge the unit on low stage. Units Equipped with Adjustable Expansion Valves should be charged by Subcooling and Superheat adjusted only if necessary.. Purge gauge lines. onnect service gauge manifold to basevalve service ports. un the system in low stage at least 0 minutes to allow pressure to stabilize.. Temporarily install a thermometer on the liquid line at the liquid line service valve and 4-6" from the compressor on the suction line. Ensure the thermometer makes adequate contact and is insulated for best possible readings. Use liquid line temperature to determine subcooling and vapor temperature to determine superheat. 3. heck subcooling and superheat. Systems with TXV application should have a subcooling of 5 to 7 F and superheat of 7 to 9 F. a. If subcooling and superheat are low, adjust TXV to 7 to 9 ºF superheat, and then check subcooling. NOTE: To adjust superheat, turn the valve stem clockwise to increase and counter clockwise to decrease. b. If subcooling is low and superheat is high, add charge to raise subcooling to 5 to 7 F then check superheat. c. If subcooling and superheat are high, adjust TXV valve to 7 to 9 ºF superheat, then check subcooling. d. If subcooling is high and superheat is low, adjust TXV valve to 7 to 9 ºF superheat and remove charge to lower the subcooling to 5 to 7 ºF. NOTE: Do NOT adjust the charge based on suction pressure unless there is a gross undercharge. 4. Disconnect manifold set, installation is complete. SUBOOLING FOMULA = SATUATED LIQUID TEMP. - LIQUID LINE TEMP. NOTE: heck the Schrader ports for leaks and tighten valve cores if necessary. Install caps finger-tight. HEAT MP - HEATING E The proper method of charging a heat pump in the heat mode is by weight with the additional charge adjustments for line size, line length, and other system components. For best results on outdoor units with TXVs, superheat should be -5 F at 4-6" from the compressor. Make final charge adjustments in the cooling cycle. S-04 HEKING OMPESSO EFFIIEN The reason for compressor inefficiency is broken or damaged scroll flanks on Scroll compressors, reducing the ability of the compressor to pump refrigerant vapor. The condition of the scroll flanks is checked in the following manner. 04

105 SEVIING. Attach gauges to the high and low side of the system.. Start the system and run a "ooling Performance Test. If the test shows: a. Below normal high side pressure. b. Above normal low side pressure. c. Low temperature difference across coil. d. Low amp draw at compressor. And the charge is correct. The compressor is faulty - replace the compressor. S-06 OVEFEEDING Overfeeding by the expansion valve results in high suction pressure, cold suction line, and possible liquid slugging of the compressor. If these symptoms are observed:. heck for an overcharged unit by referring to the cooling performance charts in the servicing section.. heck the operation of the power element in the valve as explained in S-0 hecking Expansion Valve Operation. 3. heck for restricted or plugged equalizer tube. S-07 UNDEFEEDING Underfeeding by the expansion valve results in low system capacity and low suction pressures. If these symptoms are observed:. heck for a restricted liquid line or drier. A restriction will be indicated by a temperature drop across the drier.. heck the operation of the power element of the valve as described in S-0 hecking Expansion Valve Operation. S-08 SUPEHEAT The expansion valves are factory adjusted to maintain 7 to 9 degrees superheat of the suction gas. Before checking the superheat or replacing the valve, perform all the procedures outlined under Air Flow, efrigerant harge, Expansion Valve - Overfeeding, Underfeeding. These are the most common causes for evaporator malfunction. HEKING SUPEHEAT efrigerant gas is considered superheated when its temperature is higher than the saturation temperature corresponding to its pressure. The degree of superheat equals the degrees of temperature increase above the saturation temperature at existing pressure. See Temperature - Pressure hart on following pages. AUTN To prevent personal injury, carefully connect and disconnect manifold gauge hoses. Escaping liquid refrigerant can cause burns. Do not vent refrigerant to atmosphere. ecover during system repair or final unit disposal.. un system at least 0 minutes to allow pressure to stabilize.. For best results, temporarily install a thermometer on the liquid line at the liquid line service valve and 4-6" from the compressor on the suction line. Ensure the thermometer makes adequate contact and is insulated for best possible readings. Use liquid line temperature to determine subcooling and vapor temperature to determine superheat. NOTE: An optional method is to locate the thermometer at the suction line service valve. Ensure the thermometer makes adequate contact and is insulated for best possible readings. 3. efer to the superheat table provided for proper system superheat. Add charge to lower superheat or recover charge to raise superheat. Superheat Formula = Suct. Line Temp. - Sat. Suct. Temp. EXAMPLE: a. Suction Pressure = 43 b. orresponding Temp. F. = 50 c. Thermometer on Suction Line = 6 F. To obtain the degrees temperature of superheat, subtract 50.0 from 6.0 F. The difference is Superheat.

108 SEVIING S-09 HEKING SUBOOLING efrigerant liquid is considered subcooled when its temperature is lower than the saturation temperature corresponding to its pressure. The degree of subcooling equals the degrees of temperature decrease below the saturation temperature at the existing pressure.. Attach an accurate thermometer or preferably a thermocouple type temperature tester to the liquid line as it leaves the condensing unit.. Install a high side pressure gauge on the high side (liquid) service valve at the front of the unit. 3. ecord the gauge pressure and the temperature of the line. 4. eview the technical information manual or specification sheet for the model being serviced to obtain the design subcooling. 5. ompare the hi-pressure reading to the "equired Liquid Line Temperature" chart (page 08). Find the hi-pressure value on the left column. Follow that line right to the column under the design subcooling value. Where the two intersect is the required liquid line temperature. Alternately you can convert the liquid line pressure gauge reading to temperature by finding the gauge reading in Temperature - Pressure hart and reading to the left, find the temperature in the F. olumn. 6. The difference between the thermometer reading and pressure to temperature conversion is the amount of subcooling. Add charge to raise subcooling. ecover charge to lower subcooling. Subcooling Formula = Sat. Liquid Temp. - Liquid Line Temp. EXAMPLE: a. Liquid Line Pressure = 47 b. orresponding Temp. F. = 0 c. Thermometer on Liquid line = 09 F. To obtain the amount of subcooling subtract 09 F from 0 F. The difference is subcooling. See the specification sheet or technical information manual for the design subcooling range for your unit. S-0 HEKING EXPANSN VALVE OPEATN. emove the remote bulb of the expansion valve from the suction line.. Start the system and cool the bulb in a container of ice water, closing the valve. As you cool the bulb, the suction pressure should fall and the suction temperature will rise. 3. Next warm the bulb in your hand. As you warm the bulb, the suction pressure should rise and the suction temperature will fall. 4. If a temperature or pressure change is noticed, the expansion valve is operating. If no change is noticed, the valve is restricted, the power element is faulty, or the equalizer tube is plugged. 5. apture the charge, replace the valve and drier, evacuate and recharge. S- HEKING ESTITED LIQUID LINE When the system is operating, the liquid line is warm to the touch. If the liquid line is restricted, a definite temperature drop will be noticed at the point of restriction. In severe cases, frost will form at the restriction and extend down the line in the direction of the flow. Discharge and suction pressures will be low, giving the appearance of an undercharged unit. However, the unit will have normal to high subcooling. Locate the restriction, replace the restricted part, replace drier, evacuate and recharge. S-3 OVEHAGE OF EFIGEANT An overcharge of refrigerant is normally indicated by an excessively high head pressure. An evaporator coil, using an expansion valve metering device, will basically modulate and control a flooded evaporator and prevent liquid return to the compressor. An evaporator coil, using a capillary tube metering device, could allow refrigerant to return to the compressor under extreme overcharge conditions. Also with a capillary tube metering device, extreme cases of insufficient indoor air can cause icing of the indoor coil and liquid return to the compressor, but the head pressure would be lower. There are other causes for high head pressure which may be found in the "Service Problem Analysis Guide." If other causes check out normal, an overcharge or a system containing non-condensables would be indicated. If this system is observed:. Start the system.. emove and capture small quantities of gas from the suction line dill valve until the head pressure is reduced to normal. 3. Observe the system while running a cooling performance test. If a shortage of refrigerant is indicated, then the system contains non-condensables. 08

109 SEVIING S-4 NON-ONDENSAES If non-condensables are suspected, shut down the system and allow the pressures to equalize. Wait at least 5 minutes. ompare the pressure to the temperature of the coldest coil since this is where most of the refrigerant will be. If the pressure indicates a higher temperature than that of the coil temperature, non-condensables are present. Non-condensables are removed from the system by first removing the refrigerant charge, replacing and/or installing liquid line drier, evacuating and recharging. HEKING OMPESSO EFFIIEN The reason for compressor inefficiency is broken or damaged scroll flanks on Scroll compressors, reducing the ability of the compressor to pump refrigerant vapor. The condition of the scroll flanks is checked in the following manner.. Attach gauges to the high and low side of the system.. Start the system and run a ooling Performance Test. If the test shows: a. Below normal high side pressure. b. Above normal low side pressure. c. Low temperature difference across coil. d. Low amp draw at compressor. And the charge is correct. The compressor is faulty replace the compressor. S-5 OMPESSO BUNOUT When a compressor burns out, high temperature develops causing the refrigerant, oil and motor insulation to decompose forming acids and sludge. If a compressor is suspected of being burned-out, attach a refrigerant hose to the liquid line dill valve and properly remove and dispose of the refrigerant. NOTIE Violation of EPA regulations may result in fines or other penalties. Now determine if a burn out has actually occurred. onfirm by analyzing an oil sample using a Sporlan Acid Test Kit, AK-3 or its equivalent. emove the compressor and obtain an oil sample from the suction stub. If the oil is not acidic, either a burnout has not occurred or the burnout is so mild that a complete clean-up is not necessary. If acid level is unacceptable, the system must be cleaned by using the clean-up drier method. AUTN Do not allow the sludge or oil to contact the skin. Severe burns may result. NOTE: The Flushing Method using - refrigerant is no longer approved by Amana Brand Heating-ooling. Suction Line Drier lean-up Method The POE oils used with 40A refrigerant is an excellent solvent. In the case of a burnout, the POE oils will remove any burnout residue left in the system. If not captured by the refrigerant filter, they will collect in the compressor or other system components, causing a failure of the replacement compressor and/or spread contaminants throughout the system, damaging additional components. Install a field supplied suction line drier. This drier should be installed as close to the compressor suction fitting as possible. The filter must be accessible and be rechecked for pressure drop after the system has operated for a time. It may be necessary to use new tubing and form as required. NOTE: At least twelve () inches of the suction line immediately out of the compressor stub must be discarded due to burned residue and contaminates.. emove compressor discharge line strainer.. emove the liquid line drier and expansion valve. 3 Purge all remaining components with dry nitrogen or carbon dioxide until clean. 4. Install new components including liquid line drier. 5. Braze all joints, leak test, evacuate, and recharge system. 6. Start up the unit and record the pressure drop across the drier. 7. ontinue to run the system for a minimum of twelve () hours and recheck the pressure drop across the drier. Pressure drop should not exceed 6 PSIG. 8. ontinue to run the system for several days, repeatedly checking pressure drop across the suction line drier. If the pressure drop never exceeds the 6 PSIG, the drier has trapped the contaminants. emove the suction line drier from the system. 9. If the pressure drop becomes greater, then it must be replaced and steps 5 through 9 repeated until it does not exceed 6 PSIG. NOTIE: egardless, the cause for burnout must be determined and corrected before the new compressor is started. 09

110 SEVIING S-0 EFIGEANT PIPING The piping of a refrigeration system is very important in relation to system capacity, proper oil return to compressor, pumping rate of compressor and cooling performance of the evaporator. POE oils maintain a consistent viscosity over a large temperature range which aids in the oil return to the compressor; however, there will be some installations which require oil return traps. These installations should be avoided whenever possgible, as adding oil traps to the refrigerant lines also increases the opportunity for debris and moisture to be introduced into the system. Avoid long running traps in horizontal suction line. S-0 LEANING ALUMINUM OILS This unit is equipped with an aluminum tube evaporator coil. The safest way to clean the evaporator coil is to simply flush the coil with water. This cleaning practice remains as the recommended cleaning method for both copper tube and aluminum tube residential cooling coils. An alternate cleaning method is to use one of the products listed in the technical publication TP-09 (shipped in the literature bag with the unit) to clean the coils. The cleaners listed are the only agents deemed safe and approved for use to clean round tube aluminum coils. TP-09 is available on the web site in Partner Link > Service Toolkit. NOTE: Ensure coils are rinsed well after use of any chemical cleaners. S-0 DUT STATI PESSUES AND/O STATI PES- SUE DOP AOSS OILS This minimum and maximum allowable duct static pressure for the indoor sections are found in the specifications section. Tables are also provided for each coil, listing quantity of air (FM) versus static pressure drop across the coil. Too great an external static pressure will result in insufficient air that can cause icing of the coil. Too much air can cause poor humidity control and condensate to be pulled off the evaporator coil causing condensate leakage. Too much air can also cause motor overloading and in many cases this constitutes a poorly designed system. S-03 SINGLE PIEE AI HANDLE EXTENAL STATI To determine proper airflow, proceed as follows:. Using a Inclined Manometer or Magnehelic gauge, measure the static pressure of the return duct at the inlet of the air handler, this will be a negative pressure (for example-.30"wc). Measure the static pressure of the supply duct at the outlet of the air handler, this should be a positive pressure (for example.0"wc). 3. Add the two readings together (for example -.30"wc +.0"wc =.50"wc total external static pressure. NOTE: Both readings may be taken simultaneously and read directly on the manometer if so desired. 4. onsult proper air handler airflow chart for quantity of air (FM) at the measured external static pressure. +.0 wc -.30 wc S-03A TWO PIEE AI HANDLE EXTENAL STATI PESSUE To determine proper airflow, proceed as follows:.
