tion. Please contact your local dealer for more infor-
mation.

1. SAFETY PRECAUTIONS

To gain full advantage of the air conditioner’s func-
tions and to avoid malfunction due to mishandling, 
we recommend that you read this instruction manual 
carefully before use.
This air conditioner is classified under “appliances 
not accessible to the general public”.

The precautions described herein are classified 
as WARNING and CAUTION. They both contain 
important information regarding safety. Be sure 
to observe all precautions without fail.

WARNING

....... Failure to follow these instruc-

tions properly may result in per-
sonal injury or loss of life.

CAUTION

........ Failure to observe these 

instructions properly may result 
in property damage or personal 
injury, which may be serious 
depending on the circum-
stances.

After reading, keep this manual in a convenient 
place so that you can refer to it whenever neces-
sary. If the equipment is transferred to a new 
user, be sure also to hand over the manual. 

WARNING

Be aware that prolonged, direct exposure to 
cool or warm air from the air conditioner, or to 
air that is too cool or too warm can be harmful 
to your physical condition and health.

When the air conditioner is malfunctioning 
(giving off a burning odor, etc.) turn off power 
to the unit and contact your local dealer.

Continued operation under such circumstances may 
result in a failure, electric shocks or fire hazards.

Consult your local dealer about installation work.

Doing the work yourself may result in water leak-
age, electric shocks or fire hazards.

Ask your dealer to install in a machine room 
that has no water drops by raining.
This unit is for indoor use.

Incomplete installation performed by yourself may 
result in a water leakage, electric shock, and fire.

Consult your local dealer regarding modifica-
tion, repair and maintenance of the air condi-
tioner.

Improper workmanship may result in water leak-
age, electric shocks or fire hazards.

Do not place objects, including rods, your fin-
gers, etc., in the air inlet or outlet.

Injury may result due to contact with the air condi-
tioner’s highspeed fan blades.

Never touch the air outlet or the horizontal 
blades while the swing flap is in operation.

Fingers may become caught or the unit may break 
down.

Beware of fire in case of refrigerant leakage.

If the air conditioner is not operating correctly, i.e. 
not generating cool or warm air, refrigerant leak-
age could be the cause. Consult your dealer for 
assistance. 
The refrigerant within the air conditioner is safe 
and normally does not leak. However, in the event 
of a leakage, contact with a naked burner, heater 
or cooker may result in generation of noxious gas. 
Do not longer use the air conditioner until a quali-
fied service person confirms that the leakage has 
been repaired.
