Remove the capillary tube. 4. Re-install the components by referring to notes. TES Replacement of the refrigeration cycle.. When replacing the refrigeration cycle, be sure to Discharge the refrigerant system using a Freon TM recovery System. If there is no valve to attach the recovery system, install one (such as a WATCO A-) before venting the Freon TM. Leave the valve in place after servicing the system.. After discharging the unit completely, remove the desired component, and unbraze the pinch-off tubes. 3. Solder service valves into the pinch-off tube ports, leaving the valves open. 4. Solder the pinch-off tubes with Service valves. 5. Evacuate as follows. ) Connect the vacuum pump, as illustrated figure 6A. ) Start the vacuum pump, slowly open manifold valves A and B with two full turns counterclockwise and leave the valves open. The vacuum pump is now pulling through valves A and B up to valve C by means of the manifold and entire system. CAUTION If high vacuum equipment is used, just crack valves A and B for a few minutes, then open slowly with the two full turns counterclockwise. This will keep oil from foaming and being drawn into the vacuum pump. 3) Operate the vacuum pump vaccum for 0 to 30 minutes, until 600 microns of vaccum is obtained. Close valves A and B, and observe vacuum gauge for a few minutes. A rise in pressure would indicate a possible leak or moisture remaining in the system. With valves A and B closed, stop the vacuum pump. 4) Remove the hose from the vacuum pump and place it on the charging cylinder. See figure 6B. Open valve C. Discharge the line at the manifold connection. 5) The system is now ready for final charging. 6. Recharge as follows : ) Refrigeration cycle systems are charged from the High-side. If the total charge cannot be put in the High-side, the balance will be put in the suction line through the access valve which you installed as the system was opened. ) Connect the charging cylinder as shown in figure 6B. With valve C open, discharge the hose at the manifold connection. 3) Open valve A and allow the proper charge to enter the system. Valve B is still closed. 4) If more charge is required, the high-side will not take it. Close valve A. 5) With the unit running, open valve B and add the balance of the charge. a. Do not add the liquid refrigerant to the Lowside. b. Watch the Low-side gauge; allow pressure to rise to 30 lbs. c. Turn off valve B and allow pressure to drop. d. Repeat steps b. and c. until the balance of the charge is in the system. 6) When satisfied the unit is operating correctly, use the pinch-off tool with the unit still running and clamp on to the pinch-off tube. Using a tube cutter, cut the pinch-off tube about inches from the pinch-off tool. Use sil-fos solder and solder pinch-off tube closed. Turn off the unit, allow it to set for a while, and then test the leakage of the pinch-off connection.

No power Power supply cord Rotary switch Wire disconnected or connection loose Capacitor (Discharge capacitor before testing.) Will not rotate Revolves on overload. Fan Blower Loose clamper Worn bearings Voltage Wiring Rotary Check voltage at outlet. Correct if none. Check voltage to rotary switch. If none, check power supply cord. Replace cord if circuit is open. Check switch continuity. Refer to wiring diagram for terminal identification. Replace switch if defective. Connect wire. Refer to wiring diagram for terminal identification. Repair or replace loose terminal. Test capacitor. Replace if not within ±0% of manufacturer's rating. Replace if shorted, open, or damaged. Fan blade hitting shroud or blower wheel hitting scroll. Realign assembly. Units using slinger ring for condenser fan must have /4 to 5 /6 inch clearance to the base. If it hits the base, shim up the bottom of the fan motor with mounting screw(s). Check fan motor bearings; if motor shaft will not rotate, replace the motor. Check voltage. If not within limits, call an electrician. Test capacitor. Check bearings. Does the fan blade rotate freely? If not, replace fan motor. Pay attention to any change from high speed to low speed. If the speed does not change, replace the motor. If cracked, out of balance, or partially missing, replace it. If cracked, out of balance, or partially missing, replace it. Tighten it. If knocking sounds continue when running or loose, replace the motor. If the motor hums or noise appears to be internal while running, replace motor. Check voltage. If not within limits, call an electrician. Check the wire connections, if loose, repair or replace the terminal. If wires are off, refer to wiring diagram for identification, and replace. Check wire locations. If not per wiring diagram, correct. Check for continuity, refer to the wiring diagram for terminal identification. Replace the switch if circuit is open. 30

31 COMPLAINT CAUSE REMEDY Compressor will not run, but fan motor runs. Compressor cycles on overload. Compressor cycles on overload. Compressor cycles on overload. Insufficient cooling or heating Excessive noise Thermostat Capacitor (Discharge capacitor before servicing.) Compressor Overload Voltage Overload Fan motor Condenser air flow restriction Condenser fins (damaged) Capacitor Wiring Refrigerating system Air filter Exhaust damper door Unit undersized Blower or fan Copper tubing Check the position of knob If not at the coldest setting, advance the knob to this setting and restart unit. Check continuity of the thermostat. Replace thermostat if circuit is open. Check the capacitor. Replace if not within ±0% of manufacturers rating. Replace if shorted, open, or damaged. Check the compressor for open circuit or ground. If open or grounded, replace the compressor. Check the compressor overload, if externally mounted. Replace if open. (If the compressor temperature is high, remove the overload, cool it, and retest.) Check the voltage. If not within limits, call an electrician. Check overload, if externally mounted. Replace if open. (If the compressor temperature is high, remove the overload, cool, and retest.) If not running, determine the cause. Replace if required. Remove the cabinet. inspect the interior surface of the condenser; if restricted, clean carefully with a vacuum cleaner (do not damage fins) or brush. Clean the interior base before reassembling. If condenser fins are closed over a large area on the coil surface, head pressures will increase, causing the compressor to overload. Straighten the fins or replace the coil. Test capacitor. Check the terminals. If loose, repair or replace. Check the system for a restriction. If restricted, clean of replace. Close if open. Determine if the unit is properly sized for the area to be cooled. Check the set screw or clamp. If loose or missing, correct. If the blower or fan is hitting air guide, rearrange the air handling parts. Remove the cabinet carefully and rearrange tubing not to contact cabinet, compressor, shroud, and barrier. 3
