Troubleshooting measures are classifi ed into the following two types on a remedial basis.

•

Not malfunction

The following conditions do not indicate a problem with the system.

•

Check

Please check again before calling a repair person.

•

The air conditioner does not operate.
(OPERATION lamp is off.)

Is a breaker off or a fuse blown?

•

Is there a power failure?

•

Are batteries set in the remote controller?

•

Is the timer setting correct?

•

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. (The system is designed to start
discharging air only after it has reached a certain
temperature.)

Operation stopped suddenly.
(OPERATION lamp is on.)

For system protection, the air conditioner may stop

•

operating on a sudden large voltage fl uctuation. It
automatically resumes operation in about 3 minutes.

Operation stopped suddenly.
(OPERATION lamp flashes.)

Are the air filters clean?

•

Clean the air filters.
Is there anything to block the air inlet or the outlet of the

•

indoor and the outdoor units?
Turn the breaker off and take all obstacles away. Then

•

turn it on again and try operating the air conditioner with
the remote controller. If the lamp still flashes, call the
service shop where you purchased the air conditioner.

Mist comes out of the indoor unit.

This happens when the air in the room is cooled into

•

mist by the cold airflow during COOL operation.
This is because the air in the room is cooled by the heat

•

exchanger and becomes mist during defrosting
operation.
