Troubleshooting

Check the points described below before requesting repair.

Symptom

Cause

It is not a malfunction.

Outdoor unit

• White, misty, cold air or water comes

out

• The fan of the outdoor unit is automatically

stopped and defrosting is performed.

• Sometimes the noise of air 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 draining.

• 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.

• Discharged air smells unusual.

• Various smells from the walls, carpet, clothes,

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

• The unit does not run.

•  Has a blackout occurred?
•  Has the circuit breaker blown?
•  Has the protective device been activated?

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

Check again.

The room does not cool down.

• Is the air intake or discharge of the outdoor unit

clogged?

• Is a door or window open?
• Is the air

lter clogged with dust?

• Is the air volume set to “LOW”? Or is the

operation mode set to “FAN”?

• Is the setup temperature appropriate?

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.

) is displayed on the remote

controller LCD, inform the dealer of its content as well.

If any of the following occur, stop running the unit immediately, turn off the circuit breaker, and contact the dealer
where you purchased the product.

•  The switch does not work properly.
•  The circuit breaker often blows out.
•  You unintentionally put a foreign object or water inside.
•  The unit cannot be run even after the cause of the protective device activation is removed.
•  Other unusual conditions are found.

NOTE

For environmental conservation, it is strongly recommended that the indoor and outdoor units of the air conditioner
in use be cleaned and maintained regularly to ensure ef

cient operation of the air conditioner.

When the air conditioner is operated for a long time, periodic maintenance (once a year) is recommended.
Furthermore, regularly check the outdoor unit for rust and scratches, and remove them or apply rustproof
treatment, if necessary.
As a general rule, when an indoor unit is operated for 8 hours or more daily, clean the indoor unit and outdoor unit
at least once every 3 months. Ask a professional for this cleaning / maintenance work.
Such maintenance can extend the life of the product though it involves the owner’s expense.
Failure to clean the indoor and outdoor units regularly will result in poor performance, freezing, water leakage, and
even compressor failure.
