WARNING
• Only a qualified person is allowed to perform
maintenance without daily maintenance.
• Before touching any of connection wirings, be
sure to turn off all power supply switches.
• Do not use flammable materials (e.g., hair-
spray or insecticide) near the product.
Do not clean the product with organic solvents
such as paint thinner.
The use of organic solvents may cause crack
damage to the product, electric shocks, or fire.
• Contact professional personnel about attach-
ment 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.

tion, turn the breaker off or remove the power
cord.
Otherwise, an electric shock and injury may result.
• Do not wash the air conditioner with water, as
this may result in electric shocks or fire.
• Consult your dealer regarding cleaning the
inside of the air conditioner.
Improper cleaning may cause breakage of plastic
parts, water leakage and other damage as well as
electric shocks.

ing or inspection.
High-place work is required, to which utmost
attention must be paid.

Maintenance and inspection
• Clean the drain pan periodically. The drain pipes
clogged with dust will cause water leakage.
• For cleaning, consult with your Daikin dealer.
(Before each season when cooling or heating is
required, clean the air conditioner.)
• If the area around the indoor unit is very dusty, use
a dust-proof cover (local procurement).
Cleaning the inside of the indoor unit
• It is necessary to clean the inside of the indoor unit
periodically.
Since the cleaning requires special technologies,
request a Daikin dealer to clean them.
