2. SAFETY CONSIDERATIONS

We recommend that you read this instruction man­ual carefully before use to gain full advantage of the
function of the air conditioner, and to avoid malfunc­tion due to erroneous handling.
This air conditioner comes under the term

“appliances not accesible to the general public”.

• The precautions described below are WARN­ING and CAUTION. These are very important
precautions concerning safety. Be sure to
observe all of them without fail.

WARNING .. These are the matters with possi-

bilities leading to serious conse­quences such as death or serious
injury due to erroneous handling.

CAUTION ... These are the matters with possi-

bilities leading to injury or material
damage due to erroneous han­dling including probabilities lead­ing to serious consequences in
some cases.

• 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.

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 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 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 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.

CAUTION

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.

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 use any fuse with improper capacity.

The use of a piece of wire and whatnot may
result in a failure and fire.
