more, make certain that this operation manual
is handed to a new user when he takes over
the operation.
WARNING
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 dete-
riorated and/or your health may be ruined.
When the air conditioner is in abnormal con-
ditions (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 con-
ditioner.
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 mea-
sures so that the amount of any leaked refriger-
ant does 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 compo-
nent 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.
Do not use any fuse with improper capacity.
The use of a piece of wire and whatnot may
result in a failure 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 ser-
vice person confirms to finish repairing the por-
tion where the refrigerant leaks.
CAUTION
Do not use the air conditioner for other purposes.
Do not use the air conditioner for a special appli-
cation 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.
Check and make sure that foundation blocks
are not damaged after a long use.
If they are left in a damaged condition, the unit
may fall and result in injury.
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.
Otherwise, an electric shock and injury may result.
Do not operate the air conditioner with a wet hand.
An electric shock may result.
Do not place items that might be damaged by
water under the indoor unit.
Water may condensate and drip if the humidity
reaches 80% or if the drain exit gets clogged.
Do not place a burner or heater at a place directly
exposed to the wind from the air conditioner.
Incomplete combustion of the burner or heater
may result.
Do not allow a child to mount on the outdoor
unit or avoid placing any object on it.
Falling or tumbling may result in injury.
Do not expose animals and plants directly to
the wind from the air conditioner.
Adverse influence to animals and plants may result.
Do not wash the air conditioner with water.
Electric shock or fire may result.
Do not install the air conditioner at any place
where flammable gas may leak out.
If the gas leaks out and stays around the air con-
ditioner, a fire may break out.
Be sure to install an earth leakage breaker.
Unless it is installed, an electric shock or fire may result.
