Before cleaning the air conditioner, be sure to turn it off and disconnect the power supply cord.
Be sure the intake grille (Fig. 1 8) is installed securely.
When removing and replacing the air filters, be sure not to touch the heat exchanger, as personal
injury may result.
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 grille seems to catch
partway through its movement, continue lifting up-
ward to remove.
2 Pull past the intermediate catch and open the Intake
Grille wide so that it become horizontal.
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 Pull the knobs all the way.
2 Hold the grille horizontal and set the left and right
mounting shafts into the bearings at the top of the
panel.
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 shaded 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 holes in the panel.
2 Close the intake grille.
(For purposes of example, the illustration shows the unit
without 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.
