Maintenance and Service

When the air conditioner is not going to be used for a long time.

Operate the air conditioner on mode for 2 to
3 hours.

• This will dry out the internal mechanisms.

When air conditioner is not going to be
used for a long time.

When the air conditioner is to be used again.

Turn off the circuit breaker, and disconnect
the plug.

(Refer to page 22 for cleaning filters.)

Check that the air inlet and outlet of the
indoor/outdoor unit are not blocked.

Keep the room temperature
uniform.

Adjust the vertical and
horizontal airflow direction to
ensure a uniform temperature
in the room.

Ventilate the room

It seems that condensation
is leaking from the air
conditioner.

effectively.

The air conditioner
operation is noisy.

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

• 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.
