CLEANING AND CARE
CAUTION!
Cleaning the Intake Grille
1. Remove the intake grille.
1 Place your fingers at both lower ends of the grille
panel, and lift forward; if the intake grille seems to
catch partway through its movement, continue lifting
upward to remove.
2 Lift up the intake grille fully to remove.
2. Clean with water.
Remove dust with a vacuum cleaner; wipe the unit with
warm water, then dry with a clean, soft cloth.
3. Replace the intake grille.
1 Holding the intake grille horizontally, fasten the two
upper hooks on the unit.
2 Press the intake grille down at the lower sides to close.
Cleaning the Air Filter
1. Open the intake grille, and remove the air
filter.
Lift up the air filter’s handle, disconnect the two lower
tabs, and pull out.
2. Remove dust with a vacuum cleaner or by
washing.
After washing, allow to dry thoroughly in a shady place.
3. Replace the air filter and close the intake
grille.
1 Align the sides of the air filter with the panel, and push
in fully, making sure the two lower tabs are returned
properly to their openings in the panel.
2 Close the intake grille.
(In the illustration, the unit is shown without the intake grille
installed.)
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.
When using the optional Air Cleaning Filter
Install the optional air cleaning filter set as instructed (installation instructions are furnished with the air cleaning filter set).
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 100 °F, harsh abrasive cleansers, or volatile agents like
benzene or thinner.
Do not expose the unit body to liquid insecticides or hairsprays.
When shutting down the unit for one month or more, first allow the fan mode to operate continuously for about one-half
day to allow internal parts to dry thoroughly.
