Question

The air conditioner cannot be operated for about 3 minutes when restarted.

Cracking sound is heard.

The room smells strange.

Answer (not a malfunction)

This protects the air conditioner according to instruc- tions from the microprocessor. Please wait.

This sound is generated by the expansion/contraction of the front panel, etc. due to change in temperature.

The air conditioner sucks in an odor adhering to the wall, carpet, furniture, cloth, etc. and blows it out with the air.

Even if the above items are checked, when the air conditioner does not recover from the trouble, stop using the air conditioner and consult your dealer.

If the air conditioner had operated be- fore the power failure, as this model is equipped with an auto restart func- tion, the air conditioner should start operating again. (Refer to Description of “AUTO RESTART FUNCTION” on page 7.)

1Does the air conditioner start operating again?

The fan stops during the DRY operation.

In DRY operation, the unit operates using the same refrigerant circuit as in COOL operation. DRY opera- tion time has to be reduced in order to lower humidity without much room temperature decreasing. So the compressor sometimes stops, and at the same time the indoor fan stops. This prevents water condensed on the heat exchanger from evaporating again.

In the following cases, stop using the air conditioner and consult your dealer.

The remote control signal may
