CLEANING AND CARE

CAUTION
● 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.
Cleaning the Air 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 fi lter from the intake grille.
3. Clean the air fi lters.
Remove the dust from the air fi lters by vacuuming or wash-
ing them. After washing, allow the air fi lters to dry thor-
oughly in an area protected from sunlight.
● Dust can be cleaned from the air fi lter either with a vacuum
cleaner, or by washing the fi lter in a solution of mild deter-
gent and warm water. If you wash the fi lter, be sure to allow
it to dry thoroughly in a shady place before reinstalling.
● If dirt is allowed to accumulate on the air fi lter, air fl ow will
be reduced, lowering operating effi ciency and increasing
noise.
● After turning the power on, press the fi lter reset button on
the indoor unit to turn off the fi lter indicator lamp.
