Safety Precautions
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.
When the air conditioner is to be used again.
Operate the air conditioner on Air circulation
mode (Refer to page 14) for 2 to 3 hours.
Clean the air filter and install it in the indoor
unit.
(Refer to page 16 for cleaning filters.)
Operating Instructions
• This will dry out the internal mechanisms.
Turn off the circuit breaker, and disconnect
the plug.
Check that the air inlet and outlet of the
indoor/outdoor unit are not blocked.
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.
Troubleshooting Tips
Care and Maintenance
Remove the batteries from the remote
control.
Operation Tips
Do not overcool the room.
Keep blinds or curtains
closed.
Keep the room temperature
uniform.
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.
Adjust the vertical and
horizontal airflow direction to
ensure a uniform temperature
in the room.
Make sure that the doors
and windows are shut tight.
Clean the air filter regularly.
Ventilate the room
occasionally.
Avoid opening doors and
windows as much as possible
to keep the cool air in the room.
Blockages in the air filter
reduce the airflow and lower
cooling and dehumidifying
effects. Clean at least once
every two weeks.
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...
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?
• Has the fuse blown or has the circuit breaker
been tripped?
13
-
-
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.
• Has the temperature been set incorrectly?
• Are the indoor unit's air inlet or outlet vents
obstructed?
16
7, 10
-
-
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.

NOTE
WATER RESISTANT: The outdoor side of this appliance is WATER RESISTANT.
The indoor side is not water resistant and should not be exposed to excess water.
19
Troubleshooting Tips
• 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.
Care and Maintenance
• Check that this is not a damp smell exuded by
the walls, carpet, furniture, or cloth items in the
room.
Operating Instructions
The room has a peculiar
odor.
The air conditioner
operation is noisy.
