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 man-
ual carefully before use.
• This air conditioner is classified under “appli-
ances not accessible to the general public”.
• The precautions described herein are clas-
sified as WARNING and CAUTION. They
both contain important information regard-
ing safety. Be sure to observe all precau-
tions without fail.

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
• Consult your local dealer about installation
work.
Doing the work yourself may result in water
leakage, electric shocks or fire hazards.
• Consult your local dealer regarding modifi-
cation, repair and maintenance of the air
conditioner.
Improper workmanship may result in water
leakage, electric shocks or fire hazards.
• 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.
Do not longer use the air conditioner until a
qualified service person confirms that the leak-
age has been repaired.
• Consult your local dealer regarding reloca-
tion and reinstallation of the air conditioner.
Improper installation work may result in leak-
age, electric shocks or fire hazards.
