Maintenance
WARNING
• Only a qualified person is allowed to per-
form maintenance other than basic 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 sol-
vents such as paint thinner.
The use of organic solvents may cause crack
damage to the product, electric shocks, or fire.
• Contact professional personnel about
attachment of accessories and be sure to
use only accessories specified by the man-
ufacturer.
If a defect results from your own workmanship, it
may result in water leaks, electric shock or fire.
CAUTION
• Before cleaning, be sure to stop unit opera-
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 plas-
tic parts, water leakage and other damage as
well as electric shocks.
• Watch your steps when cleaning or inspect-
ing the air filter.
High-place work is required, to which utmost
attention must be paid.
If the scaffold is unstable, you may fall or topple
down, thus causing injury.
Maintenance and inspection
• Clean the drain pan periodically. The drain
pipes clogged with dust will cause water leak-
age.
• 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 technolo-
gies, request a Daikin dealer to clean them.
Daily maintenance:
