❏ Always use the remote control to adjust the up/down

airflow direction. Manually moving the vertical airflow direction louver by hand could damage the air conditioner.

❏ When the unit is shut off, the up/down airflow direction

louver will close the air outlet vent of the system.

To adjust left/right(Horizontal Airflow) direction Caution :

Ensure unit is turned off before adjusting the horizontal airflow direction control. Carefully open vertical louver to allow access to the horizontal airflow direction.

AIR FILTERS

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

PLASMA FILTER, DEODORIZER FILTER(OPTION)

The PLASMA filter behind the air filters should be checked and cleaned once every 3 months or more often if necessary.

❏

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.

CAUTION

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.

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 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, it is a good idea to open them and ventilate the room now and then.

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

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.
