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. Use caution when rolling on carpet surfaces. Do not attempt to roll the unit over objects.
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.

Exhaust hose installation The exhaust hose and adaptor must be installed or removed in accordance with the usage mode. Cool, Heat(heat pump type) or Auto mode Install Fan, dehumidify or heat(electrical heat type) mode Remove 1. Install the window Exhaust adaptor B onto the exhaust hose as shown in Fig.
previous pages for window kit installation. 2. Insert the hook of the Exhaust hose into the hole seat of the air outlet and slide down the Exhaust hose along the arrow direction for installation (See Fig.14) The exhaust hose can be installed into the wall (Not applicable to the units without adaptor A, expansion plugs and wooden screws of Accessories). 1. Prepare a hole in the wall.
Note: Cover the hole using the adaptor cap when not in use. The duct can be compressed or extended moderately according to the installation requirement, but it is desirable to keep the duct length to a minimum. IMPORTANT: DO NOT OVER BEND THE DUCT (SEE Fig.16) Water drainage -During dehumidifying modes, remove the drain plug from the back of the unit, install the drain connector(5/8〞universal female mender) with 3 /4〞hose(locally purchased).
drain connector, just attach the drain hose to the hole. Place the open end of the hose directly over the drain area in your basement floor. Please refer to Fig.17&18. -During heating pump mode, remove the lower drain plug from the back of the unit, install the drain connector (5/8 〞 universal female mender) with 3/4 〞 hose(locally purchased). For the models without drain connector, just attach the drain hose to the hole.
-When the water level of the bottom tray reaches a predetermined level, the unit beeps 8 times, the digital display area shows "P1". At this time the air conditioning/dehumidification process will immediately stop. However, the fan motor will continue to operate (this is normal). Carefully move the unit to a drain location. Remove the bottom drain plug and let the water drain away (see above Fig.20). Restart the machine until the "P1" symbol disappears. If the error repeats, call for service.
3. Unit idle for a long time ※Remove the rubber plug at the back of the unit and attach a hose to drain outlet. Place the open end of the hose directly over the drain area in your basement floor (See below Fig.23). ※Remove the plug from the bottom drain outlet, all the water in the bottom tray would drain out (See below Fig.23) ※Keep the appliance running on FAN mode for half a day in a warm room to dry the appliance inside and prevent mold forming.
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.
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. Attach gauges to the high and low sides of the system. 3. Start the system and run a “cooling or heating performance test.” If test shows: A. Below normal high side pressure. B. Above normal low side pressure. C.
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. No power to unit, remove the leads from the compressor terminals. 2. Using an ohmmeter, test continuity between terminals C-S and C-R.
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. Apply gauge from process tube to EPA approved gauges from process tube to EPA approved recovery system.
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. 4. Reassemble the system, including new drier strainer and capillary tube. 5. Proceed with processing as outlined under hermetic component replacement. 8.2.
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. 5. Apply "live" test cord probes on each of the remaining wires from the speed switch or system switch to test intermediate speeds. 8.
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" end of the scale and remain there as long as the probes are connected.
10 Troubleshooting In general, possible trouble is classified in three kinds. One is called Starting Failure which is caused from an electrical defect, another is ineffective Air Conditioning caused by a defect in the refrigeration circuit and improper application, and the other is called the Structure Damage. TROUBLES POSSIBLE CAUSES SUGGEST REMEDIES P1 appears in the display window Drain the water in the bottom tray. Room temperature is lower than the set temperature.
