TROUBLE SHOOTING

Trouble Shooting
These cases are not troubles.
The following cases are not air conditioner troubles but have some reasons. You may just continue using it.
Case
Operation does not start soon.
• When ON/OFF button was pressed
soon after operation was stopped.
• When the mode was reselected.
Hot air does not flow out soon
after the start of heating
operation.
The heating operation stops
suddenly and a flowing sound
is heard.
A sound is heard.
The outdoor unit emits water or
steam.
Mist comes out of the indoor
unit.
The indoor unit gives out odour. ■ This happens when smells of the room, furniture, or cigarettes
• This is to protect the air conditioner.
You should wait for about 3 minutes.
• 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 system is taking away the frost on the outdoor unit.
You should wait for about 4 to 12 minutes.
■ A sound like a flow of water
• This sound is generated because the refrigerant in the air
conditioner is flowing.
• This is a pumping sound of the water in the air conditioner
and heard when the water is pumped out from the air con-
ditioner in cooling or drying operation.
• The refrigerant flows in the air conditioner even if the air conditioner
is not working when the indoor units in other rooms are in operation.
■ Blowing sound
• This sound is generated when the flow of the refrigerant in
the air conditioner is switched over.
■ Pinging sound
• This sound is generated when the size of the air conditioner
slightly expands or shrinks as a result of temperature changes.
■ Whistling sound
• This sound is generated when refrigerant flows during
defrosting operation.
■ 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.
■ 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.
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.)
