Be sure only to use accessories made by Daikin which are
specifically designed for use with the equipment and have them
installed by a professional.

Safety considerations

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.

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

If the warning is not observed, it may cause serious casualties.

CAUTION

If the caution is not observed, it may cause injury or damage to the
equipment.

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

 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.

 Do not attempt to install or repair the air conditioner yourself.

Improper workmanship may result in water leakage, electric
shocks or fire hazards. Please contact your local dealer or
qualified personnel for installation and maintenance work.

 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 highspeed fan blades.

 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.
