Care and maintenance of the air conditioner

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

Indoor Unit

Grille, Case, and Remote Control

☐ 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 Filter

AIR FILTERS

The air filters behind the front grill should be checked and cleaned once every 2 weeks 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.

Benzene Copper Gasoline

1 Pull down the grille bottom, After lifting up the filter tab a bit and take the filter out slowly (Notice: Clean the filter after being stopped the product)
2 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.
3 After washing with water, dry well in the shade.
4 Re-install the air filter.

Outdoor Unit

The heat exchanger coils and panel vents of the outdoor unit should be checked regularly. If clogged with dirt or soot, the heat exchanger and panel vents may be professionally steam cleaned.

NOTE:

Dirty or clogged coils will reduce the operating efficiency of the system and cause higher operating costs.

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

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

Operate the air conditioner on Air circulation mode (Refer to page 14) for 2 to 3 hours.

• This will dry out the internal mechanisms.

Turn off the circuit breaker, and disconnect the plug.

CAUTION

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.

Remove the batteries from the remote control.

When the air conditioner is to be used again.

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.

Operation Tips

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.

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.	Have you made a mistake in timer operation?	13
	Has the fuse blown or has the circuit breaker been tripped?	-
The room has a peculiar odor.	Check that this is not a damp smell exuded by the walls, carpet, furniture, or cloth items in the room.	-
It seems that condensation is leaking from the air conditioner.	Condensation occurs when the airflow from the air conditioner cools the warm room air.	-
Air conditioner does not operate for about 3 minutes when restarted.	This is the protector of the mechanism.Wait about three minutes and operation will begin.	-
Does not cool or heat effectively.	Is the air filter dirty? See air filter cleaning instructions.	16
	Has the temperature been set incorrectly?	6,9
	Are the indoor unit's air inlet or outlet vents obstructed?	-
The air conditioner operation is noisy.	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.	-
Remote control display is faint, or no display at all.	Are the batteries depleted?Are the batteries inserted in the opposite (+) and (-) directions?	4
Crack sound is heard.	This sound is generated by the expansion/constriction of the front panel, etc. due to changes of temperature.	-
