sound is heard.

Shuru

 

Cracking sound is heard.

It smells.

During operation, white fog comes out of indoor unit.

It is switched into the FAN mode during cooling.

The air conditioner can not be restarted soon after it stops.

Unit does not start

Air does not blow or the fan speed can not be changed during dehumidifying

During operation, operation mode has changed over automatically.

Water or steam generates from the outdoor unit during heating.

When the air conditioner is started, when the compressor starts or stops during operation or when the air conditioner is stopped, it sometimes sounds "shuru shuru" or "gobo gobo". It is the flowing sound of the refrigerant, and it is not a trouble.

This is caused by heat expansion or contraction of plastics.

Air which blows out from the indoor unit sometimes smells. The smell results from residents of tobacco smoke or cosmetics stuck inside of unit.

When the air conditioner is used at restaurant etc. where dense edible oil fume is always exists, white fog sometimes blows out of air outlet during operation.

In this case consult sales dealer for cleaning the heat exchanger.

To prevent frost from being accumulated on the indoor unit heat exchanger, it is sometimes automatically switched to the FAN mode but it will soon return to the cooling mode.

Even if the operation switch is turned on, cooling, dehumidifying or heating is not operable for three minutes after the conditioner is stopped. Because the protecting circuit is activated.

minutes

 

When it is excessively cooled during dehumidifying, the blower automatically repeats reducing and lowering the fan speed.

In the case of AUTO mode, operation mode is changed automati- cally from cooling to heating or vise-versa according to the room temperature.

This results when frost accumulated on the outdoor unit is removed (during defrosting operation).
