Wipe off dirt with a soft, dry cloth (use a vacuum cleaner to
remove dust from the air Intake.) Use a cloth and water less
than 40°C to remove stubborn dirt (the cloth should be
well-wrung). Do not use the following cleansers as they
cause the paint to peel and lead to malfunctions: Benzene,
thinner, scouring powder, chemical-soaked cloths, etc.

* After long-term usage of room air conditioners, dust and dirt

will accumulate inside, lowering the performance. This may
cause the generation of odour or may impede the drainage of
the dehumidifying water.

* Besides regular cleaning of the air conditioner, a

separate annual check is also recommended (chargeable).
Please request your dealer to carry out these checks.

HOW TO CLEAN THE AIR FILTER

2. Vacuum the filter on the dusty side to remove light

dust.

3. Wash the filter, cleaner side up under gently flowing

water to wash out accumulated dust and lint.

the wash water.

Let the filter dry thoroughly before reinstalling it.
When reinstalling the filter, be sure the word “FRONT”
is facing you as you slide the filter back into place.
