ENGLISH

Check the following points before requesting repairs or service.... If the fault persists, please contact your dealer or
service center.

Case

Explanation

See page

The air conditioner does not
operate.

The room has a peculiar
odor.

It seems that condensation
is leaking from the air
conditioner.

Air conditioner does not
operate for about 3 minutes
when restarted.

Does not cool or heat
effectively.

The air conditioner
operation is noisy.

Remote control display is
faint, or no display at all.

Crack sound is heard.

• Have you made a mistake in timer operation?
• Has the fuse blown or has the circuit breaker

been tripped?

• Check that this is not a damp smell exuded by

the walls, carpet, furniture, or cloth items in the
room.

• Condensation occurs when the airflow from

the air conditioner cools the warm room air.

• This is the protector of the mechanism.
• Wait about three minutes and operation will

begin.

• Is the air filter dirty? See air filter cleaning

instructions.

• Has the temperature been set incorrectly?
• Are the indoor unit's air inlet or outlet vents

obstructed?

• For a noise that sounds like water flowing.

-This is the sound of freon flowing inside the

air conditioner unit.

• For a noise that sounds like the compressed

air releasing into atmosphere.

-This is the sound of the dehumidifying water

being processed inside the air conditioning
unit.

• Are the batteries depleted?
• Are the batteries inserted in the opposite (+)

and (-) directions?

• This sound is generated by the

expansion/constriction of the front panel, etc.
due to changes of temperature.
