The Timer LED blinks indicating abnormality. Press the check button at remote control for 5 seconds, error code will be displayed.

Remote Control Display.

Air is not discharged immediately

Reason

At Cooling Soft Dry (auto Fan Speed)
Air will not be discharged for approximately 40 seconds. The unit is designed to prevent tobacco, cooking and body odors from being discharged together with the cool air. At Heating (POWER LED blinks) This is to prevent cold air from blowing out. Please wait.

Operation stops suddenly

At Cooling Soft Dry (auto Fan Speed) The indoor fan repeatedly stops for 80 seconds and operates for 20 seconds to check the indoor temperature. Whenever the temperature reaches the setting temperature, operation starts again. At Heating (POWER LED blinks) When the outdoor temperature is low and humidity is high, frost accumulates on the outdoor unit. The POWER LED blinks when the unit is melting the frost. (Please wait as defrosting may take up to 10 minutes.)
Press TIMER or button to identify the error code. Beep sound (4 times) will be heard for the correct error code shown. Turn off the power supply and remove the power supply plug. Inform the error code to an authorised dealer. Depending on which 3 characters are displayed, temporary operation may be possible. Characters allowing temporary operation H23 H27 H28 Possible temporary operations Cooling Heating Cooling Description of operation Emergency operation with limited functions. (The Timer LED continues to blink.)
Fog is blowing out from the unit There is a noise
This occurs when the airflow from the air conditioner cools the room. A passt sound is heard during defrosting or when the air conditioner operation has been stopped. This is caused by the refrigerant inside the air conditioner flowing in the opposite direction. The air conditioner will expand or contract due to changes in temperature, causing a cracking sound. The sound of water flowing is caused by the refrigerant flowing inside the unit. When defrosting, the frost melts and changes to water and steam.

G Temporary operation
