❏ Turn the system off before cleaning. To

clean, wipe with a soft, dry cloth. Do not
use bleach or abrasives.

NOTE:

Supply power must be disconnected before
cleaning the indoor unit.

AIR FILTERS

The air filters behind the front grille should be
checked and cleaned once every 2 weeks or
more often if neccessary.

❏

Never use any of the followings:

• Water hotter than 40°C
Could cause deformation and/or
discoloration.

• Volatile substances
Could damage the surfaces of the air
conditioner.

Lift the front access panel and pull the filter tab
slightly forward to remove the filter.

Clean the filter with a vacuum or warm, soapy
water.

• If dirt is conspicuous, wash with a
solution of detergent in lukewarm water.

• If hot water (40°C or more) is used, it
may be deformed.

After washing with water, dry well in the
shade.

Re-install the air filter.

Outdoor Unit

The heat exchanger coils and panel vents of the

clogged with dirt or soot, the heat exchanger
and panel vents may be professionally steam
cleaned.

NOTE:

Dirty or clogged coils will reduce the

When the air conditioner is to be used again.

Turn off the circuit breaker, and disconnect

Remove the batteries from the remote
control.

Whentheairconditionerisnotgoingtobeusedforalongtime.

Turn off the circuit breaker when the air conditioner
is not going to be used for a long time.

Dirt may collect and may cause a fire.

Clean the air filter and install it in the indoor
unit.
(Refer to page 13 for cleaning filters.)

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

Do not overcool the room.

This is not good for the health
and wastes electricity.

Make sure that the doors
and windows are shut tight.

Avoid opening doors and
windows as much as possible
to keep the cool air in the room.

Keep blinds or curtains
closed.

Do not let direct sunshine enter
the room when the air
conditioner is in operation.

Clean the air filter regularly.

Blockages in the air filter
reduce the airflow and lower
cooling and dehumidifying
effects. Clean at least once
every two weeks.

Keep the room temperature
uniform.

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

Ventilate the room
occasionally.

Since windows are kept closed,
it is a good idea to open them
and ventilate the room now and
then.

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.
