1. Contact an installation specialist for installation.

2. Use a dedicated circuit.

1. Being exposed to direct airflow for an extended period of time could be hazardous to your health.

Do not expose occupants, pets, or plants to direct airflow for extended periods of time.

2. Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves or

other heating devices.

3. Do not use this air conditioner for non-specified special purposes (e.g. preserving precision

devices, food, pets, plants, and art objects). Such usage could damage the items.

1. Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling

sharp metal edges.

2. Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation,

leading to possible electric shock.

CAUTION

CAUTION

Operation Tips

Operate the air conditioner on Air
circulation mode 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 used again.

Turn off the circuit breaker.

Remove the batteries from the remote
controller.

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 13 for cleaning filters.)

Check that the air inlet and outlet of the
indoor/outdoor unit are not blocked.

Check that the ground wire is
connected correctly. It may be
connected to the indoor unit side.

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
reduces the airflow and lowers
the cooling and dehumidifying
effects. Clean at least once in
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.

Maintenance and Service

Before you call for service...

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

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 controller 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.
