Troubleshooting

These cases are not troubles.
The following cases are not air conditioner troubles but have some reasons. You may just continue using it.

after operation was stopped.
•
When the mode was reselected.
Hot air does not fl ow out soon after
the start of HEAT operation.

and a fl owing sound is heard.
A sound is heard.
The outdoor unit emits water or

The indoor unit gives out odour.
30
•
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 fl ow of water
•
This sound is generated because the refrigerant in the air conditioner is fl owing.
•
This is a pumping sound of the water in the air conditioner and heard when the water is
pumped out from the air conditioner in cooling or drying operation.
•
The refrigerant fl ows 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 fl ow of the refrigerant in the air conditioner is
switched over.
Ticking sound
•
This sound is generated when the size of the air conditioner slightly expands or shrinks
as a result of temperature changes.
Clicking sound during operation or idle time
•
This sound is generated when the refrigerant control valves or the electrical parts
operate.
Clopping sound
•
This sound is heard from the inside of the air conditioner when the exhaust fan is
activated while the room doors are closed. Open the window or turn off the exhaust fan.
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.
This happens when the air in the room is cooled into mist by the cold airfl ow
during cooling operation.
This is because the air in the room is cooled by the heat exchanger and
becomes mist during defrost operation.
This happens when smells of the room, furniture, or cigarettes are absorbed
into the unit and discharged with the airfl ow.
(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.)
