CARE AND MAINTENANCE
WARNING!
Never operate the air conditioner without the filters in place
Before cleaning the indoor unit, ensure the unit is turned off and all the power supply has been disconnected.
Do not touch the aluminum fins of heat exchanger built-in the indoor unit to avoid personal injury when you
maintain the unit
CAUTION
Only use a soft, dry cloth to wipe the unit clean. If the unit is especially dirty, you can use a cloth soaked in warm
water to wipe it clean.
Do not use chemicals or chemically treated cloths to clean the unit
Do not use benzene, paint thinner, polishing powder or other solvents to clean the unit. They can cause the
plastic surface to crack or deform.
Do not use water hotter than 104°F (40°C) to clean the front panel. This can cause the panel to deform or be-
come discolored.
Do not expose filter to direct sunlight when drying. This can shrink the filter.
CLEANING THE AIR FILTER
Note: The high density filters and 3M carbon filters come pre-installed.
To ensure the air intake is filtered properly and to assure that your air condi-
tioner runs efficiently, it is recommended to clean the washable high density
filters at least once every two weeks.
Lift the indoor unit panel up to an angle until it stops with a clicking
sound. (See Fig. 15.1)
Pull up the handle of the high density filters in direction of the arrow and
release from the filter holder. Then pull the filters out with gently sliding
it downward. (See Fig. 15.2 and 15.3)
