• Wipe with a soft dry cloth.

At the end of the season

Operate the air conditioner at the following
settings for 2 to 3 hours.

• Type of operation : Cooling.

• Temperature setting : 30°C.

This will dry out the internal mechanisms.
Remove the batteries from the Remote Control.

Turn off the circuit breaker.

Turn off the circuit breaker when the air conditioner
isnotgoingtobeusedforalongtime.

Dirt may collect and may cause a fire.

Clean the air filters, re-insert, then operate
the air conditioner.

Be sure that nothing obstructs the air outlet
and intake vents.

At the start of the season

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

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

Never use any of the followings.

Cleaning of the air cleaner.

• Re-insert the air cleaner to the original position.

CAUTION: Before performing any maintenance, turn off the main power to the system.

During the season

Do not overcool the room.

This is not good for your 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.

Safety PrecautionsOperating InstructionsCare and MaintenanceTroubleshooting Tips

Before you call for service...

Check the following points before requesting repairs or service.... If the fault persists, please

contact your dealer or service center.

Troubleshooting Tips! Save time and money!

Case Explanation See page

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 controller 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?

• Is the power Switch at Off?

• Is the unit at the starting of Heating Operation?

If yes, Hot-start is activating.

• Is the unit in the Deicing?
If yes, wait for finishing the Deicing.

• 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 Protection device of the air conditioner .

• Wait about three minutes and operation will begin.

• If the airflow begins before its temperature become

warm, it will cause an undesired cooling effect. In
order to prevent this, the airflow will not begin until
it is sufficiently warm.

• Is the air filter dirty? See air filter cleaning
instructions.

• The room may have been very hot when the room
air conditioner was first turned on. Allow time for it
to cool down.

• 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?
