ENGLISH
Prior to Operation
Preparing for Operation
1. Contact an installation specialist for installation.
2. Use a dedicated circuit.
Usage
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.
Cleaning and Maintenance
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,

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 unitʼs power is
accidentally triggered on while cleaning inner parts of the unit.

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 at the
following settings for 2 to 3 hours.
• Type of operation: Fan operation mode.
• This will dry out the internal mechanisms.
Turn off the breaker.
Clean the air filter and install it in the
indoor unit.
Check that the air inlet and outlet of the
indoor/outdoor unit are not blocked.
CAUTION
Turn off the 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 ground wire is
connected correctly. It may be connect
to the indoor unit side.
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.
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.

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
restart.
• 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.
Does not cool or heat
effectively.
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
unit.
• For a noise that
sounds like the

-This is the sound of
the dehumidifying
water being
processed inside the
air conditioning unit.
• Have you made a
mistake in timer
operation?
• Has the fuse blown
or has the circuit
breaker been
tripped?
• This sound is generated
by the expansion/
constriction of the front
panel, etc. due to
changes of temperature.
Remote control
