Symptom Cause
Cold white mist or water comes
out. Occasionally there is a
shushing sound.
●
The fan of the outdoor unit have stopped automatically and defrosting is
being performed.
●
The solenoid valve makes this sound when defrosting starts or finishes.
There is an occasional sound
like running water
● When the operation has started, during running, or immediately after
running has stopped, a sound like water flowing may be heard, and the
operation sound may become louder for 2 or 3 minutes immediately after
the operation has started. This is the sound of the refrigerant circulating or
the humidifier draining.
There is a hissing sound
● This sound is generated when the heat exchanger, etc. expands and con-
tracts slightly due to a change in temperature.
The expelled air smells
● Various smells such as that of the wall, carpet, clothes, cigarettes, or cos-
metics adhere to the air conditioner.
The preparation indicator is lit
●
Cooling cannot be performed because another indoor unit is performing
heating.
(Standard type only)
● Is the outdoor temperature out of the operation temperature range?
The running mode lock
indicator is lit
● This is lit when there is an attempt to start an operation which has not
been set by the air conditioner administrator.
The pre heat indicator is lit
●
The fan has been stopped to prevent the expelling of cool air.
●
The outdoor unit is performing defrosting.
Sound, white vapour, or cool
air is coming out from a non-
operating indoor unit
● Refrigerant is being circulated temporarily to prevent the accumlation of
oil or refrigerant in indoor units on stand by. This can cause sounds, white
vapour (when in heating mode) or cool air (when in cooling mode) to
come out of unused indoor units.
The air conditioner makes a clicking
noise when it is turned on

is turned on.
