Trouble Shooting
The following cases are not air conditioner troubles but have some reasons. You may just continue
using it.
These cases are not troubles.
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 flow out soon
after the start of heating
operation.
• The air conditioner is warming up. You should wait for 1 to 4
minutes.
(The system is designed to start discharging air only after it
has reached a certain temperature.)
The heating operation stops
suddenly and a flowing 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 mode
• The frost on the outdoor unit melts into water or steam
when the air conditioner is in defrost operation.
In COOL or DRY mode
• 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 flow during cooling 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 odour.
This happens when smells of the room, furniture, or
cigarettes are absorbed into the unit and discharged with the
air flow.
(If this happens, we recommend you to have the indoor unit
washed by a technician. Consult the service shop where you
bought the air conditioner.)
The outdoor fan rotates while
the air conditioner is not in
operation.
After operation is stopped:
• The outdoor fan continues rotating for another 60 seconds
for system protection.
While the air conditioner is not in operation:
• When the outdoor temperature is very high, the outdoor
fan starts rotating for system protection.
The operation stopped
suddenly.
(OPERATION lamp is on.)
For system protection, the air conditioner may stop operating
on a sudden large voltage fluctuation.
It automatically resumes operation in about 3 minutes.
