1. SAFETY PRECAUTIONS
To gain full advantage of the air conditioner’s func-
tions and to avoid malfunction due to mishandling,
please read this operation 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 odour, etc.) turn off the
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 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.
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 used for the air condi-
tioner is safe and normally does not leak.
However, if the refrigerant leaks and gets in con-
tact with a naked burner, heater or cooker, it may
generate hazardous compounds. Turn off the air
conditioner and call the dealer. Make sure to turn
on the air conditioner after the qualified service
person confirms that the leakage is repaired.
Consult your local dealer regarding what to do
in case of refrigerant leakage.
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 refrigerant
does not exceed the concentration limit in the
event of a leakage. Otherwise, this may lead to an
accident due to oxygen depletion.
Contact professional personnel about attach-
ment of accessories and be sure to use only
accessories specified by the manufacturer.
If a defect results from your own workmanship, it
may result in water leaks, electric shock or fire.
Consult your local dealer regarding relocation
and reinstallation of the air conditioner.
Improper installation work may result in leakage,
electric shocks or fire hazards.
