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.

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).
