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 is always exists, white fog sometimes blows out of air outlet during
operation. In this case consult sales dealer for cleaning the heat exchanger.

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).
