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 classi-
fied 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 conve-
nient place so that you can refer to it when-
ever necessary. 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 odour, 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 haz-
ards.
Consult your local dealer about installation
work.
Doing the work yourself may result in water leak-
age, electric shocks or fire hazards.
Consult your local dealer regarding modifi-
cation, repair and maintenance of the air con-
ditioner.
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 con-
ditioner’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
leakage 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.
