The following incidents do not indicate a malfunctioning air conditioner and have explanations. The air conditioner can continue to
operate.
Case
Explanation
Operation does not start soon.
When “ON/OFF” button was pressed soon after
•
operation was stopped.
When the mode was reselected.
•
This is to protect the air conditioner.
•
You should wait for about 3 minutes.
Hot air does not
fl
ow out soon after the
start of HEAT operation.
The air conditioner is warming up. You should wait for 1 to 4 minutes.

a
fl
owing sound is heard.
The system is taking away the frost on the outdoor unit.
•
You should wait for about 4 to 12 minutes.
The outdoor unit emits water or steam.
In HEAT operation
The frost on the outdoor unit melts into water or steam when the air conditioner is in
•
defrost operation.
In COOL or DRY operation
Moisture in the air condenses into water on the cool surface of outdoor unit piping and
•
drips.
Mist comes out of the indoor unit.
This happens when the air in the room is cooled into mist by the cold air
fl
ow
during COOL operation.
This is because the air in the room is cooled by the heat exchanger and
becomes mist during defrost operation.
The indoor unit gives out odor.
This happens when smells of the room, furniture, or cigarettes are absorbed
into the unit and discharged with the air
fl
ow.
If this happens, it is recommended to have the indoor unit washed by a
technician. Consult the service shop where you purchased the air conditioner.
The outdoor fan rotates while the air
conditioner is not in operation.

•
While the air conditioner is not in operation
When the outdoor temperature is very high, the outdoor fan starts rotating for system
•
protection.
Operation stopped suddenly.

fl
uctuation.
It automatically resumes operation in about 3 minutes.
