    8 Installation details  8.1 Installation instructions  Location Your installation location should meet the following requirements: -Make sure that you install your unit on an even surface to minimize noise and vibration. -The unit must be installed near a grounded plug, and the Collection Tray Drain (found on the back of the unit) must be accessible.
  • Page 19 Type wall installation: Step 2: Install the Exhaust hose assembly to the unit Push the Exhaust hose into the airoutlet opening of the unit along the arrow direction. Step 3:Preparing the Adjustable Window Slider 1. Choose the window sliders according the size of your window. Sometimes, it needs to be cut short to meet the window size, please take extra care to cut it properly.
  • Page 20 2. Use bolts to fasten the window sliders once they are adjusted to the Proper length.
  • Page 21 Exhaust Hose Installation Note: Once the Exhaust Hose assembly and Adjustable Window Slider are prepared, choose from one of the following two installation methods. Type 1: Hung Window Installation or or Sliding Window Installation(For some models) 1. Cut the adhesive foam seal A and B strips to the proper lengths, and attach them to the window sash and frame as shown.
  • Page 22 2. Insert the window slider assembly into the window opening. 3. Cut the non-adhesive foam seal C strip to match the width (or height) of the window. Insert the seal between the glass and the window frame to prevent air and insects from getting into the room 4.

    NOTE: To ensure proper function, DO NOT overextend or bend the hose. Make sure that there is no obstacle around the air outlet of the exhaust hose (in the range of 500mm) in order to the exhaust system works properly. All the illustrations in this manual are for explanation purpose only. Your air conditioner may be slightly different.

  • Page 25: 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 26 9.1.3 Checking the compressor efficiency 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.

    the motor windings to sense the winding temperature and/or current draw. The overload is 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.
  • Page 28 9.2.3 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.

    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.

    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"...

    11 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...

  • Page 33: Error Codes And Solution

    Error codes and Solution  E1---Room temperature sensor error. E2---Evaporator temperature sensor error. Causation: a) Port of temperature sensor is loose. b) Temperature sensor is bad. c) Circuit component is bad. Solution: a) Check the connection between temperature sensor and adaptor is ok, if not, please make sure the port plugs into the adaptor hard.
