Page 21: Installation Details
8 Installation details 8.1 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 22 Window Installation Kit(Optional) Step 1: Preparing the Exhaust Hose assembly Press the exhaust hose into the window slider adaptor (into wall window slider adaptor for wall installation) and unit adaptor, clamp automatically by elastic buckles of the adaptors. Step 2: Install the Exhaust hose assembly to the unit Insert unit adaptor of the Exhaust hose assembly into the lower groove of the air outlet of the unit while the hook of the adaptor is aligned with the hole seat of the air outlet and slide down the Exhaust hose assembly along the arrow direction for installation.
- Page 23 Note: Once the Exhaust Hose assembly and Adjustable Window Slider are prepared, choose from one of the following three installation methods. Type 1: Hung Window Installation(optional)
- Page 24 Type 2: Sliding Window Installation(optional)
- Page 25 Type 3: Wall Installation(optional) -Cut a 125mm (4.9inch) hole into the wall for the Wall Exhaust Adaptor B. -Secure the Wall Exhaust Adaptor B to the wall using the four Anchors and Screws provided in the kit. -Connect the Exhaust Hose Assembly(with Wall Exhaust Adaptor A) to the Wall Exhaust Adaptor B. Note: To ensure proper function, DO NOT overextend or bend the hose.
- Page 26 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). For the models without 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.

-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. - Page 28 Cleaning Wash the air filter by immersing it gently in warm water (about 40℃/104℉) with a neutral detergent. Rinse the filter and dry it in a shady place. Mounting Install the upper air filter after cleaning and install the lower filter by using the screw. NOTE: The grill and the air filer are connected and can’t be separated.

Page 29: Basic Test Procedure
9 Basic test procedure 9.1 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. 9.1.1 Compressor wiring test Remove compressor terminal box cover and disconnect wires from terminals. - Page 30 Terminal "R" and "S" - no continuity - Open winding - replace compressor. 9.1.2 Ground test Use an ohmmeter to set on its highest scale. Touch one lead to the compressor body (clean point of contact as a good connection is a must) and the other probe in turn to each compressor terminal (see Figure 2.) If a reading is obtained, the compressor is grounded and must be replaced.

1. High amperage. 2. Low refrigerant charge. 3. Frequent recycling. 4. Dirty condenser. 9.1.5 Terminal overload – Test (compressor external type) 1. Remove overload. 2. Allow time for overload to reset before attempting to test. 3. Apply ohmmeter probes to terminals on overload wires. There should be continuity through the overload. - Page 32 8. Accurate refrigerant charge measuring device such as: a. Balance Scales - 1/2 oz. accuracy b. Charging Board - 1/2 oz. accuracy 9. High Pressure Gauge - (0 - 400 lbs.) 10. Low Pressure Gauge - (30 - 150 lbs.) 11.

NOTE: This process can be speeded up by use of heat lamps, or by breaking the vacuum with refrigerant or dry nitrogen at 5,000 microns. Pressure system to 5 PSIG and leave in system a minimum of 10 minutes.

as possible to the nameplate charge. 2. The correct method for charging the rotary is to introduce liquid refrigerant into the high side of the system with the unit off. Then start compressor and enter the balance of the charge, gas only, into the low side. - Page 35 Capacitor test: 1. Remove capacitor from unit. 2. Check for visual damage such as bulges, cracks, or leaks 3. For dual rated, apply an ohmmeter lead to common (C) terminal and the other probe to the compressor (HERM) terminal. A satisfactory capacitor will cause a deflection on the pointer, and then gradually move back to infinity.
