mode (Refer to page 15) for 2 to 3 hours.

• This will dry out the internal parts.

Turn off the circuit breaker.

2

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.

a long time.

CAUTION

Operation Tips

Do not overcool the room.

This is not good for the health and wastes electricity.

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

nCheck that the air inlet and outlet of the

indoor/outdoor unit are not blocked.

Helpful information

The air filters and your electiric bill. If the air filters become clogged with dust, the cooling capacity will drop, and 6% of the electricity used to operate the air conditioner will be wasted.

Keep blinds or curtains

closed.

When the air conditioner is to

be used again.

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.

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.

Ventilate the room

occasionally.

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

Troubleshooting Tips

Before you call for service...

Troubleshooting Tips! Save time and money!

Check the following points before requesting repairs or service.... If the malfunction persist, please contact your

dealer.

Case Explanation See page

The air conditioner does not operate.

The room has a peculiar odor.

It seems that condensate is leaking from the air Conditioner.

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

Does not cool or heat effectively.

The air conditioner operation is noisy.

Crack sound is heard.

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

l

Have you made a mistake in timer operation?

l

On first starting, the indoor unit operates in

fifteen seconds.

l

Has the fuse blown or has the circuit breaker

been tripped?

l

Check power supply for single/reverse phase, voltage imbalance.

l

Check that this is not a damp smell exuded by

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

l

Condensation occurs when the airflow from the

air conditioner cools the warm room air.

l

This is the protector of the mechanism.

l

Wait about three minutes and operation will

begin.

l

Is the air filter dirty? See air filter cleaning

instructions.

l

The room may have been very hot when the

room air conditioner was first turned on. Allow time for it to cool down.

l

Has the setting temperature been set

incorrectly?

l

Are the indoor unit's air inlet or outlet vents

obstructed?

l

For a noise that sounds like water flowing.

-This is the sound of freon flowing inside the air conditioner unit.

l

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.

l

This sound is generated by the

expansion/contraction of the inlet grille, etc. due to changes of temperature.

l

Has the circuit breaker been tripped?
