WARNING
• Only a qualified person is allowed to perform mainte-
nance outside of daily maintenance.
• Before touching any of connection wirings, be sure to
turn off all power supply switches.
• Do not use flammable materials (for example, hairspray
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.
• Never put your fingers or rods in the air inlet, air outlet,
or horizontal blade.
The fan is rotating at high speed, so you would get injured.
• Contact your dealer 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.
CAUTION
• Before cleaning, be sure to stop unit operation, 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.
• Use appropriate equipment at the time of air filter clean-
ing or inspection.
Work at higher elevation requires a ladder or scaffolding. If
these are unstable you may fall, thus causing injury.
NOTE
• Do not remove the air filter except for cleaning. Operat-
ing the unit without an air filter may result in failure.
• Do not attach substances (such as paper towels) other
than the specified air filter to the air inlet.
The performance may drop and cause freeze-up/water
leakage.
