Page 17: Installation Details
7 Installation details 7.1 Installation instructions Location The air conditioner should be placed on a firm foundation to minimize noise and vibration. For safe and secure positioning, place the unit on a smooth, level floor strong enough to support the unit. The unit has casters to aid placement, but it should only be rolled on smooth, flat surfaces. - Page 18 Note: If the window opening is less than the mentioned minimum length of the window slider kit, cut that one with a hole in it short to fit for the window opening. Do never cut out the hole in window slider kit.

Page 28: Basic Test Procedure
8 Basic test procedure 8.1 Defective compressor Compressors are single phase, depending on the model unit. All compressor motors are permanent split capacitor type using only a running capacitor across the start and run terminal. All compressors are internally spring mounted and externally mounted on rubber isolators. 8.1.1 Compressor wiring test Remove compressor terminal box cover and disconnect wires from terminals. - Page 29 The reason for compressor inefficiency is normally due to broken or damaged suction and/or discharge valves, reducing the ability of the compressor to pump refrigerant gas. This condition can be checked as follows: 1. Install a piercing valve on the suction and discharge or liquid process tube. 2.

connected in series with the common motor terminal. Should the internal temperature and/or current draw become excessive; the contacts in the overload will open, turning off the compressor? The overload will automatically reset, but may require several hours before the heat is dissipated. 8.1.7 Checking the internal overload 1. - Page 31 8.2.3 Hermetic compressor replacement. The following procedure applies when replacing components in the sealed refrigeration circuit or repairing refrigerant leaks. (Include Compressor, condenser, evaporator, capillary tube, refrigerant leaks, etc.) 1. Recover the refrigerant from the system at the process tube located on the high side of the system by installing a line tap on the process tube.

Page 32: Fan Motor
1. Recover all refrigerant and oil from the system. 2. Remove compressor, capillary tube and filter drier from the system. 3. Flush evaporator condenser and all connecting tubing with dry nitrogen or equivalent, to remove all contamination from system. Inspect suction and discharge line for carbon deposits. Remove and clean if necessary. -
Page 33: Capacitor
1. Determine that capacitor is serviceable. 2. Disconnect fan motor wires from fan speed switch or system switch. 3. Apply "live" test cord probes on black wire and common terminal of capacitor. Motor should run at high speed. 4. Apply "live" test cord probes on red wire and common terminal of capacitor. Motor should run at low speed. -

and then gradually move back to infinity. 4. Reverse the leads of the probe and momentarily touch the capacitor terminals. The deflection of the pointer should be two times that of the first check if the capacitor is good. 5. Repeat steps 3 and 4 to check fan motor capacitor. NOTE: A shorted capacitor will indicate a low resistance and the pointer will move to the "0"... -
