TROUBLESHOOTING  
I Normal Operation  
Is it okay?  
I Call the Dealer Immediately  
If the following conditions occur, turn off and unplug the  
main power supply, and then call the dealer immediately.  
This is the answer  
This is to protect the air conditioner. Wait until the air  
conditioner begins to operate.  
Air conditioner has been restarted, but does not  
operate for 3 minutes.  
Abnormal noise is heard during operation.  
This is the sound of refrigerant flowing inside the air  
conditioner.  
A sound like water flowing can be heard.  
Water or foreign material gets into the remote  
control by mistake.  
Condensation occurs when the airflow from the air  
conditioner cools the room.  
It seems that fog is coming out from the air  
conditioner.  
Water leak from the indoor unit.  
This may be a damp smell emitted by the wall,  
carpet, furniture or clothing in the room.  
The room has a peculiar odour.  
Switches or buttons do not operate properly.  
The circuit breaker switches off frequently.  
In COOL/DRY operation, moisture in the air  
condenses into water on the cool surface of outdoor  
unit piping that causes dripping.  
The outdoor unit emits water or steam.  
This is to remove the smell emitted by the  
surroundings.  
During Automatic Airflow Volume setting,  
indoor fan stops occasionally.  
Power supply cord and plug become unusually  
warm.  
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.)  
(For Heat Pump Model only)  
Operation stops for about 12 minutes during  
heating (The power indicator blinks).  
This is to prevent undesired cooling effect during  
heating operation.  
(For Heat Pump Model only)  
During heating operation, indoor fan may  
run at on and off conditions.  
I Abnormal Operation  
Is it okay?  
The air conditioner does not operate.  
Please check  
Has the circuit breaker been tripped?  
Has the power plug been removed from the wall  
outlet?  
Is the timer being used correctly?  
Air conditioner produces loud noise during  
operation.  
Is the installation work slanted?  
The air conditioner does not cool or warm  
effectively.  
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?  
Remote control / display doesnt work  
Batteries empty?  
Batteries correctly inserted (+) and ()?
