Important information regarding the refrigerant 
used

This product contains fluorinated greenhouse gases 
covered by the Kyoto Protocol.

(1)

 GWP = global warming potential

Periodical inspections for refrigerant leaks may be 
required depending on European or local legisla-
tion.
Please contact your local dealer for more informa-
tion.

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 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 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. 
Do not longer use the air conditioner until a qual-
ified service person confirms that the leakage 
has been repaired.
