CLEANING AND CARE

Grille Hook

Air Filter

CAUTION!

Cleaning the Air Filter

When the filter lamp flashes, remove and
clean the filter.

1. Push the intake grille’s hooks inward to-

wards the center of the unit to open the
intake grille.

2. Pull out the filter from the intake grille.

Before cleaning the unit, be sure to stop the unit and disconnect the power supply.

Turn off the electrical breaker.

A fan operates at high speed inside the unit, and personal injury could result.

Be careful not to drop the intake grille.

When used for extended periods, the unit may accumulate dirt inside, reducing its performance. We recommend that the
unit be inspected regularly, in addition to your own cleaning and care. For more information, consult authorized service
personnel.

When cleaning the unit’s body, do not use water hotter than 40 °C, harsh abrasive cleansers, or volatile agents like
benzene or thinner.

Do not expose the unit body to liquid insecticides or hairsprays.

If the unit will not be operated for a period of one month or more, be sure to allow the inner parts of the unit to dry
thoroughly, in advance, by operating the unit in fan mode for half a day.

3. Clean the air filters.

Remove the dust from the air filters by vacuuming or
washing them. After washing, allow the air filters to dry
thoroughly in an area protected from sunlight.

4. Re-attach the air filters to the intake grille.

1

Replace the air filter into its holder.

2

Make sure that the air filter makes contact with the
filter stopper when it is replaced into its holder.

5. Close the intake grille and push the intake

grille’s hooks outward.

Dust can be cleaned from the air filter either with a
vacuum cleaner, or by washing the filter in a solution of
mild detergent and warm water. If you wash the filter, be
sure to allow it to dry thoroughly in a shady place before
reinstalling.

If dirt is allowed to accumulate on the air filter, air flow
will be reduced, lowering operating efficiency and in-
creasing noise.

After turning the power on, press the filter button on the
remote control to turn off the filter lamp. (Refer to the
operation manual packed with remote control unit for
details.)
