After reading, keep this manual at a place where any
user can read at any time. Furthermore, make certain
that this operation manual is handed to a new user
when he takes over the operation.
Avoid exposure of your body directly to the cold air for
a long time, or avoid excessive exposure of your body
to the cold air.
Otherwise, your physical condition may be deteriorated
and/or your health may be ruined.
When the air conditioner is in abnormal conditions
(smell of something burning, etc), unplug the power
cord from the outlet, and contact the dealer where you
purchased the air conditioner.
Continued operation under such circumstances may result
in a failure, electric shock, and fire.
Ask your dealer for installation of the air conditioner.
Incomplete installation performed by yourself may result in
a failure, a water leakage, electric shock, and fire.
Ask your dealer for improvement, repair and
maintenance.
Incomplete improvement, repair, and maintenance may
result in a failure, a water leakage, electric shock, and fire.
Do not insert your finger, a stick, etc., into the air inlet,
outlet, and fan blades.
A fan in high-speed running may result in injury.
For refrigerant leakage, consult your dealer.
When the air conditioner is to be installed in a small room,
it is necessary to take proper measures so that the amount
of any leaked refrigerant dose not exceed the limiting
concentration even when it leaks. If the refrigerant leaks
exceeding the level of limiting concentration, an oxygen
deficiency accident may happen.
For installation of separately sold component parts,
ask a specialist.
Be sure to use the separately sold component parts
designated by our company.
Incomplete installation performed by yourself may result in
a failure, a water leakage, electric shock, and fire.
Ask your dealer to move and reinstall the air
conditioner.
Incomplete installation may result in a failure, a water
leakage, electric shock, and fire.
The refrigerant in the air conditioner is safe and
normally does not leak. If the refrigerant leaks inside
the room, the contact with a fire of a burner, a heater
or a cooker may result in a harmful gas.
Do not use the air conditioner until when a service person
confirms to finish repairing the portion where the
refrigerant leaks.
Do not use the air conditioner for other purposes.
Do not use the air conditioner for a special application
such as the storage of foods, animals and plants, precision
machines, and art objects as otherwise the deterioration of
quality may result.
Do not remove the air outlet of the outdoor unit.
The fan may get exposed and result in injury.
When the air conditioner is used in combination with
burners or heaters, perform sufficient ventilation.
Insufficient ventilation may result in an oxygen deficiency
accident.

Neither place a flammable spray bottle near the air
conditioner nor perform spraying.
Doing so may result in a fire.
To clean the air conditioner, stop operation, and
unplug the power cord from the outlet.
