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.

● 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.

● Before cleaning the air conditioner, be sure to turn it off and disconnect the power supply cord.

● Be sure the intake grille is installed securely.

● When removing and replacing the air filters, be sure not to touch the heat exchanger, as personal

injury may result.

● Dust can be cleaned from the air filter either with a vacuum

cleaner, or by washing the filter in a solution of mild de-

tergent and warm water. If you wash the filter, be sure to

allow it to dry thoroughly in a shady place before rein-

stalling.

● If dirt is allowed to accumulate on the air filter, air flow

will be reduced, lowering operating efficiency and increas-

ing noise.

● During periods of normal use, the air filters should be

cleaned every two weeks.
