Shuru

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.

Water flowing sound is heard.

This is caused by heat expansion or contraction of plastics.Cracking sound is heard.

It smells. 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 always

exists, white fog sometimes blows out of air outlet during operation.

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

During operation, white fog comes

out of indoor unit.

Unit does

not start

Wait for

three

minutes

It is switched into the FAN mode

during cooling.

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. (During this time air conditioner operates in fan

mode.)

The air conditioner can not be

restarted soon after it stops.

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 it is excessively cooled during dehumidifying, the blower automatically repeats

reducing and lowering the fan speed.

Isn't the AUTO mode selected?

In the case of AUTO mode, operation mode is changed automatically 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).
