After reading, keep this manual in a conve-
nient place so that you can refer to it whenever
necessary. If the equipment is transferred to a
new user, be sure also to hand over the man-
ual.
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 the
power to the air conditioner and contact your
local dealer.
Continued operation under such circumstances
may result in a failure, electric shocks or a fire.
Consult your local dealer about installation
work.
Doing the work yourself may result in water leak-
age, electric shocks or a fire.
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 a fire.
Do not place objects, including rods, your
fingers, etc., in the air inlet or outlet.
Injury may result due to contact with the air con-
ditioner’s highspeed fan blades.
Beware of a fire in case of refrigerant leak-
age.
If the air conditioner is not operating correctly,
i.e. not generating cool or warm air, refrigerant
leakage could be the cause. Consult your local
dealer for assistance. The refrigerant used for
the air conditioner is safe and normally does not
leak. However, if the refrigerant leaks and gets in
contact with a naked burner, heater or cooker, it
may generate hazardous compounds. Turn off
the air conditioner and call your local dealer.
Turn on the air conditioner after the qualified ser-
vice person makes sure to confirm that the leak-
age is repaired.
Consult your local dealer regarding what to
do in case of refrigerant leakage.
When the indoor unit is installed in a small room,
it is necessary to take proper measures 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
attachment of accessories and be sure to
use only accessories specified by the manu-
facturer.
If a defect results from your own workmanship, it
may result in water leakage, electric shocks or a
fire.
