Indoor Unit

Prior to Operation

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.

3. When cleaning the unit, first make sure that the power and breaker are turned off. The fan rotates

at a very high speed during operation. There is a possibility of injury if the unit’s power is
accidentally triggered on while cleaning inner parts of the unit.

For repair and maintenance, contact your authorized service dealer.

cooling and dehumidifying
effects. Clean at least once
every two weeks.

Ventilate the room

occasionally.

Since windows are kept
closed, it is a good idea to
open them and ventilate the
room now and then.

CAUTION

CAUTION

Operation Tips

Helpful information

The air filters and your electiric bill.
If the air filters become clogged with dust, the
cooling capacity will drop, and 6% of the electricity
used to operate the air conditioner will be wasted.

When it 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 for 2 to 3 hours.

• This will dry out the internal parts.

Turn off the circuit breaker.

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.

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.

Keep blinds or curtains

closed.

Do not let direct sunshine
enter the room when the air
conditioner is in operation.

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

• 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.

The air conditioner

does not operate.

The room has a

peculiar odor. 

It seems that

condensation is

leaking from the air

conditioner.

• 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

• 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.

• This sound is generated

by the expansion/
constriction of the front
panel, etc. due to
changes of
temperature.

• Cleaning the filter,

press the Timer button
and 

button of wired

remote controller at
the same time for 3
sec.

• Are the batteries
