Step1 .Remove the air conditioner from it's packaging, remove fixing screws and slide the air conditioner out of it's housing (Refer to Installation Steps) Step2 .Prepare the hole in the wall so that the bottom of the housing is well supported, the top has minimum clearance and the air inlet louvers have clearance as shown below in options A and B (see below 6.4.3).
ensure the foam sealing strips on the housing remain in position. ※ Connect the air conditioner to the power and position excess cord length beneath the air conditioner base. ※Engage the chassis fixing brackets into the bottom housing rail and secure to the base with the screw provided.
brackets (See Fig.5) .Grasp the handle on the chassis and carefully slide the air conditioner out of the cabinet (See Fig. 6) . When need to drain off water, install the drain plug on the chassis board. Then fix the cabinet on the supporter (provide for yourself or contact the dealer)(see Fig.7).
9 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. Operation panel don't work.

Display keeps showing "Ed". Check whether the evaporator frosts. Check whether the indoor air inlet is blocked. Check whether the indoor ambient temperature is too low. Check whether the indoor dust filter is too dirty. Check whether there is too much water on the chassis. Check the wiring of pipe temperature sensor.

Compressor doesn't work. Check whether the indoor temperature is lower than 15¡ ã C or larger than 31¡ ã C . Check the power supply. Check whether the voltage is too high or too low. Check the wiring. Check whether the compressor is under overload protection. Check the relay of compressor in PCB works normally.

Cooling mode don't work or cooling not enough. Check the operation mode. Check the setting temperature. Check whether dust filter is too dirty. Start the unit with cooling mode, check whether the temperature of the compressor's discharge pipe is smaller than 90 ℃ , if no, recharge refrigerant. Replace the capillary.
