CAUTION

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

Operation Tips

Operate the air conditioner on Air circulation mode (Refer to page 14) 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.

Remove the batteries from the remote control.

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 16 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, itisagoodideatoopenthem and ventilate the room now and then.

Before you call for service...

Troubleshooting Tips! Save time and money!

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.
