TROUBLESHOOTING
Normal Operation
Is it okay?
• Air conditioner has been restarted, but does not operate for 3 minutes.
• A sound like water flowing can be heard.
• It seems that fog is coming out from the air conditioner.
• The room has a peculiar odour.
• During Automatic Vertical Airflow setting, indoor fan stops occasionally.
• The outdoor unit emits water or steam.
• (For Heat Pump Model only) Operation stops for about 12 minutes during heating (The power indicator blinks).
• (For Heat Pump Model only) During heating operation, indoor fan may run at on and off conditions.
Abnormal Operation
Is it okay?
• The air conditioner does not operate.
• Air conditioner produces loud noise during operation.
• The air conditioner does not cool or warm effectively.
This is the answer
• This is to protect the air conditioner. Wait until the air conditioner begins to operate.
• This is the sound of refrigerant flowing inside the air conditioner.
• Condensation occurs when the airflow from the air conditioner cools the room.
• This may be a damp smell emitted by the wall, carpet, furniture or clothing in the room.
• This is to remove smell emitted by the surroundings.
• In COOL/DRY operation, moisture in the air condenses into water on the cool surface of outdoor unit piping that causes dripping.
• This is to melt the frost which has accumulated on the outdoor unit (defrosting operating). This will take no longer than about 12 minutes. Water drips from the outdoor unit. Wait until this operation ends. (the power indicator will light up). (Frost will accumulates on the outdoor unit when the outdoor temperature is low and humidity is high.)
• This is to prevent undesired cooling effect during heating operation.
Please check
• Has the circuit breaker been tripped?
• Has the power plug been removed from the wall outlet?
• Is the timer being used correctly?
• Is the installation work slanted?
• Is the front grille closed properly?
• Has the temperature been set incorrectly?
• Are the filters dirty?
• Are the intake or outlet vents of the outdoor unit obstructed?
• Are all windows and doors closed?
Call the Dealer Immediately
If the following conditions occur, turn off and unplug the main power supply, and then call the dealer immediately.
• Abnormal noise is heard during operation.
• Water or foreign material gets into the remote control by mistake.
• Water leak from the indoor unit.
• Switches or buttons do not operate properly.
• The circuit breaker switches off frequently.
• Power supply cord and plug become unusually warm.
