Cause
It is not a failure.
Outdoor

• White, misty, cold air or water
comes out
• The fan of the outdoor unit is automatically stopped
and defrosting is performed.

leaking is heard.
• The solenoid valve works when defrosting starts or
stops.
• A noise is heard when the
power is turned on.
• The outdoor unit is preparing for running.
Indoor
unit
• Sometimes a swishing is
heard.
• When the unit starts running, during operation, or
immediately after the unit stops running, a sound
such as water
owing may be heard, or the operation
sound may become louder for a couple of minutes
immediately after the unit starts running. This is the
sound of the refrigerant
owing or the dehumidi
er

• A clacking sound is heard.
• This is a sound generated when the heat exchanger
or other part expands and contracts slightly due to
temperature change.

cigarette, cosmetics or other things adhere to the air
conditioner.

even after the unit operation is
stopped.
• The fan keeps running to self clean the heat
exchanger during drying.
• The unit does not run.

(The operation indicator and on the remote controller
are blinking.)
Check again.

clogged?

If there is something unusual even after checking the above, stop running the unit, turn off the circuit
breaker, and inform the dealer where you purchased the product of the product number and symptom. Do
not attempt to repair the unit by yourself as doing so is dangerous. If the check indicator (e.g. , ,

dealer where you purchased the product.
