035600400A004 CLEARANCES All units require certain clearances for proper operation and service. Refer to Figure 3 for the clearances required for combustion, construction, servicing and proper unit operation. WARNING:Do not permit overhanging structures or shrubs to obstruct the condenser air discharge outlet. DUCT WORK These units are adaptable to downflow use as well as rear supply and return air duct openings. To convert to downflow, use the following steps:. Remove the duct covers found in the bottom return and supply air duct openings. There are four (4) screws securing each duct cover (save these screws to use later).. Install the duct covers, removed in step one, to the rear supply and return air duct openings. Secure with the four (4) screws used in step one. 3. Seal duct covers with silicone caulk. Downflow units must have an L shaped supply duct without any outlets or registers located below the outlet of the unit. Duct work should be designed and sized according to the methods of the Air Conditioning Contractors of America (ACCA), as set forth in their Manual D. A closed return duct system shall be used. This shall not preclude use of economizers or ventilation air intake. Flexible joints may be used in the supply and return duct work to minimize the transmission of noise. CAUTION: When fastening duct work to the side duct flanges on the unit, insert the screws through the duct flanges only. DO NOT insert the screws through the casing. Outdoor duct work must be insulated and waterproofed. NOTE: Be sure to note supply and return openings. Refer to Figure 3 for information concerning rear and bottom supply and return air duct openings. FILTERS Single phase units are shipped without a filter and is the responsibility of the installer to secure a filter in the return air ductwork or install a Filter/Frame Kit (FF04). A filter rack and phase units. high velocity filters are standard on three Filters must always be used and must be kept clean. When filters become dirt laden, insufficient air will be delivered by the blower, decreasing your units efficiency and increasing operating costs and wearandtear on the unit and controls. Filters should be checked monthly especially since this unit is used for both heating and cooling. CONDENSATE DRAIN A condensate trap is required to be installed in the condensate drain. The plumbing must conform to local codes. Use a sealing compound on male pipe threads. Install the condensate drain line ( 3 4 NPTF) to spill into an open drain.

035600400A004 Checking Supply Air To check the supply air after the initial balancing has been completed:.remove the two ¼ inch dot plugs in the duct panel..insert at least 8 inches of ¼ inch tubing into each of these holes for sufficient penetration into the airflowon both sides of the indoor coil. 3.Using an inclined manometer, determine the pressure drop across the dry evaporator coil. Since the moisture on an evaporator coil may vary greatly, measuring the pressure drop across a wet coil under field conditions would be inaccurate. To ensure a dry coil, the compressors should be deactivated while the test is being run. 4.Knowing the pressure drop across a dry coil, the actual through the unit can be determined from the curve in Coil Delta P vs. Supply Air figure. WARNING! Failure to properly adjust the total system air quantity can result in extensive system damage. After readings have been obtained, remove the tubes and reinstall the two ¼ inch plugs removed in Step. NOTE: Deenergize the compressors before taking any test measurements to ensure a dry indoor coil.

035600400A004 Antishort Cycle Timer This unit has an antishort cycle timer built in to the defrost control. This timer will not permit the compressor to start within five minutes after the completion of the last cycle or power interruption. To bypass the antishort cycle feature, short the TEST pins together for seconds. The following sequences of operation are based on using a standard singlestage heat pump thermostat. Cooling Operation WITH POWER TO UNIT AND THERMOSTAT IN COOLING MODE.. If the fan switch on the thermostat is in the ON position, the 4 volts at G will energize the K" relay on the fan control board, close the K" relay contacts, and energize the indoor blower motor. If the fan switch on the thermostat is in the AUTO position, the blower will operate only when there is a call for cooling by the thermostat.. On a call for cooling, the thermostat will send 4 volts to Y and O on the fan control board. After the antishort cycle period is complete,the 4 volt signal will energize contactor M", and the reversing valve solenoid. Power will be supplied to the compressor and outdoor fan motor, and the reversing valve will switch to the cooling position. If the fan switch on the thermostat is on the AUTO" position, the fan control will energize the indoor blower. 3. When the demand for cooling has been satisfied, the 4 volt Y signal is removed and the M" contactor will be deenergized. If the fan switch on the thermostat is in the ON" position, the indoor blower will continue to run. If the fan switch is in the AUTO position, the K" relay will open and deenergize the indoor blower motor after a 60 second delay, Heating Operation WITH POWER TO UNIT AND THERMOSTAT IN HEATING MODE. SEQUENCE OF OPERATION. If the fan switch on the thermostat is in the ON position, the 4 volts at G will energize the K" relay on the fan control board, close the K" relay contacts, and energize the indoor blower motor. If the fan switch on the thermostat is in the AUTO position, the blower will operate only when there is a call for heating by the thermostat.. On a call for heating, the thermostat will send 4 volts to Y on the fan control board. After the antishort cycle period is complete, the 4 volts signal will energize contactor coil M" and power will be supplied to the compressor and outdoor fan motor. The reversing valve will remain in the heating position. If the fan switch on the thermostat is in the AUTO" position, the fan control will energize the indoor blower. 3. For units equipped with supplementary electric heat, if the heat pump cannot meet the demand, the thermostat W will send 4 volts to W" on the fan control board. This signal will also be sent through the defrost control terminals W" and W/66" and back to the fan control W". This 4 volt signal will energize all stages of electric heat. 4. When the heating demand is satisfied, the electric heat will be deenergized when the 4 volt W signal is removed, and the M" contactor will be deenergized when the 4 volt Y" signal is removed. If the fan switch on the thermostat is in the ON position, the indoor blower will continue to run. If the fan switch is in the AUTO position, the K" relay will open and deenergize the indoor blower motor after the appropriate time delay. Please refer to Tables 7 and 8 for more information. Defrost Operation The minimum time between defrosts can be field selected at 30, 60 or 90 minutes. The default time is 90 minutes if the jumper is not installed. Defrost will initiate when the defrost sensor, located on the outdoor coil, senses a temperature below 3 and when the time since the last defrost is greater than the selected time on the defrost control. The defrost cycle terminates when either the defrost sensor reaches 55 or the unit has been in defrost mode for 0 minutes. If the room thermostat opens during defrost, the unit will resume operation in defrost when the thermostat recloses. During the defrost mode, the defrost control will provide a 4 volt signal from terminal W/66" to the fan control terminal W". This signal will energize electric heat stage, if the unit is so equipped. For trouble shooting purposes, the defrost cycle can be manually initiated by shorting the TEST pins together for 5 seconds. Defrost will terminate normally during the TEST mode. Heat Pump Safety Switch Operation If the unit is equipped with the field installed upgrade safety package, the refrigeration system will be protected against high or low refrigerant pressure and low indoor coil temperature. If any of these three safety switches opens, the unit will be shut off for the 5 minute antishort cycle time. Once this has expired, a six hour elapsed run timer begins. If a second opening of a safety switch occurs during this six hour period, the compressor will be locked out. Resetting the lockout function is accomplished by;. Removing power from the control's thermostat st stage (Y) input for a time not to exceed 5 seconds (ONOFFON).. Removing power from R for more than seconds. 3. Shorting the TEST pins together for more than seconds. Electric Heat Limit Switch Operation The limit switch responds to over temperature conditions in the air duct. Opening of the device results in dropping power to the relays. The control logic will also respond by turning off the relays. After four limit cycle trips the unit goes into a hour soft lockout period. If during this period the control sees another limit cycle, the unit will go into a hard lockout condition. Once in a hard lockout state, the fan is locked on and the heaters are disabled. Only a power cycle will clear the state. During the soft lockout period, the fan responds to thermostat input but the heaters are enabled. This is to sense a failed heater relay. The limit cycle count is reset at the start of a heat request. If the limit remains open for period of 80 seconds or more, the control is immediately put into a hard lockout condition. Only a power cycle will clear this state. SECURE OWNER'S APPROVAL: When the system is functioning properly, secure the owner's approval. Show him the location of all disconnect switches and the thermostat. Teach him how to start and stop the unit and how to adjust temperature settings within the limitations of the system.
