9. Compressor 1. Remove the cabinet. (Refer to section 2) 2. Discharge the refrigerant system using FreonTM Recovery System. If there is no valve to attach the recovery system, install one (such as a watco a-1) before venting the FreonTM . Leave the valve in place after servicing the system. 3. Disconnect the 3 leads from the compressor. 4. After purging the unit completely, unbraze the suction and discharge tubes at the compressor connections. 5. Remove the 3 nuts and the 3 washers which fasten the compressor. (See Fig. 26) 6. Remove the compressor. 7. Re-instill the components by referring to the removal procedure, above. Electrical parts Figure 23 Figure 24 Figure 25 Figure 26 Disassembly 10. CAPACITOR 1. Remove the control box. (Refer to section 3) 2. Remove the screw and knobs which fasten the display panel. 3. Disconnect the 2 leads from the rocker switch and remove the panel. 4. Remove a screw and unfold the control box. (See Fig. 27) 5. Remove the screw and the clamp which fastens the capacitor. (See Fig. 27) 6. Disconnect all the leads of capacitor terminals. 7. Re-install the components by referring to the removal procedure, above. 11. POWER CORD 1. Remove the control box. (Refer to section 3) 2. Unfold the control box. (Refer to section 10) 3. Disconnect the grounding screw from the control box. 4. Disconnect 2 receptacles. 5. Remove a screw which fastens the clip cord. 6. Pull the power cord. (See Fig. 28) 7. Re-install the component by referring to the removal procedure, above. (Use only one ground-marked hole for ground connection.) 8. If the supply cord of this appliance is damaged, it must be replaced by the special cord. (The special cord means the cord which has the same specification marked on the supply cord fitted to the unit.) Figure 27 Figure 28 12. THERMISTOR 1. Remove the control box. (Refer to section 3) 2. Unfold the control box. (Refer to section 10) 3. Disconnect the thermistor terminals from main P.W.B assembly. 4. Remove the thermistor. 5. Re-install the components by referring to the removal procedure above. (See Figure 30) Figure 29 17 Room Air Conditioner Disassembly 13. SYNCHRONOUS MOTOR 1. Remove the control box. (Refer to section 3) 2. Unfold the control box. (Refer to section 10) 3. Remove the crankshaft. 4. Disconnect all the leads of the synchronous motor. 5. Remove the 2 screws which fasten the synchronous motor. (See Fig. 30) 6. Re-install the components by referring to the removal procedure, above. Figure 30 Service Manual 18 19 Room Air Conditioner Disassembly Refrigeration cycle CAUTION: Discharge the refrigerant system using FreonTM Recovery System.If there is no valve to attach the recovery system, install one (such as a WATCO A-1) before venting the FreonTM. Leave the valve in place after servicing the system. 16. CONDENSER 1. Remove the cabinet. (Refer to section 2) 2. Remove the brace and the shroud cover. (Refer to section 4) 3. Remove 2 screws which fasten the side cover.(See Fig. 31) 4. Remove the 5 or 6 screws which fasten the condenser. 5. After discharging the refrigerant completely, unbraze the interconnecting tube at the condenser connections. 6. Remove the condenser. 7. Re-install the components by referring to notes. (See Fig. 31) 17. EVAPORATOR 1. Remove the cabinet. (Refer to section 2) 2. Remove the top cover and the brace. (Refer to section 4) 3. Discharge the refrigerant completely. 4. Remove the 3 screws which fasten the evaporator at the left side and the top side. 5. Move the evaporator sideward carefully and then unbraze the interconnecting tube at the evaporator connectors. 6. Remove the evaporator. 7. Re-install the components by referring to notes. (See Fig. 32) 18. CAPILLARY TUBE 1. Remove the cabinet. (Refer to section 2) 2. Remove the brace. (Refer to section 4) 3. After discharging the refrigerant completely, unbraze the interconnecting tube at the capillary tube. 4. Remove the capillary tube. 5. Re-install the components by referring to notes. Figure 31 Figure 32 NOTICE -Replacement of the refrigeration cycle. 1. When replacing the refrigeration cycle, be sure to discharge the refrigerant system using a FreonTM recovery System. If there is no valve to attach the recovery system, install one (such as a WATCO A-1) before venting the FreonTM. Leave the valve in place after servicing the system. 2. After discharging the unit completely, remove the desired component, and unbrace 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. 1) Connect the vacuum pump, as illustrated Fig. 35A. 2) Start the vacuum pump, slowly open manifold valves A and B with two full turns counterclock wise and leave the valves closed. The vacuum pump is now pulling through valves A and B up to valve C by means of themanifold and entire system. CAUTION: If high vacuum equip ment is used, just crack valves A and B for a few minutes, then open...
