READ BEFORE OPERATION

Safety precaution

To gain full advantage of the air conditioner’s functions 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 classified as WARNING and CAUTION. They both contain important

information regarding safety. Be sure to observe all precautions without fail. 

 

After reading, keep this manual in a convenient 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 manual. 

WARNING

Failure to follow these instructions properly may result in 
personal 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 circumstances.

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 hazards.

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 modification, 

repair and maintenance of the air conditioner.

Improper workmanship may result in water leakage, 

electric shocks or fire hazards.

Do not place objects, including rods, your fingers, 

etc., in the air inlet or outlet.

Injury may result due to contact with the air 

conditioner’s high speed 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 qualified 

service person confirms that the leakage has been 
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 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 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.

Read the precautions thoroughly to avoid misuse of the equipment.

There are two kinds of safety precaution and tips listed in the following.
