Cleaning the Air Filter:
The air filter prevents dust and other particles from entering the indoor unit. Dust buildup can reduce the
efficiency of the unit. For optimum efficiency, clean the air filter every two weeks. If you live in a dusty area, it
may be necessary to clean the filter more frequently. In the event the air filter is heavily clogged and cannot
be cleaned, it is recommended to replace it with a new one.
Directions to Access, Remove, & Clean the Air Filter
1. The air filter of the cassette is located inside the air
intake grille of the unit. In order to gain access to the
filter, you will have to lower the air intake grille using
the remote control.
2. With the unit in stand-by mode, press and hold the
MODE & DOWN buttons simultaneously for 3 seconds.
This will allow you to enter the panel setting mode.
The remote control should display F2.
3. Then, press the DOWN button on the remote control.
The air intake grille will automatically start lowering.
Wait until it stops before attempting to remove the
air filter (Refer to Fig. 3,1).
4. Remove the filter from the air intake grille by following
these steps (Refer to Fig. 3.2):
a. Hold the upper edge of the filter with both hands
and gently lift upward until the upper edge is free
from the air intake grille lowering cables.
b. Lift the filter and move it forward slightly until the
filter screen is separated from all four lowering
cables.
c. Move the filter to the right until it is separated from
the air grille. Then it can be taken out for cleaning.
5. The air filter can be cleaned by using a vacuum cleaner
or rinsing it with water (Refer to Fig. 3.3).
a. If using a vacuum cleaner, ensure the air intake
side of the filter is face up, as that is the side that
will trap the dust and debris.
b. If rinsing the filter with water, ensure the air intake
side of the filter is facing down and the water runs
on the back side. This will effectively rinse the dust
and debris from the filter.
6. Reinstall the filter by reversing step 4.
7. Press the UP button on the remote control to raise the
air intake grille back into place.
NOTE: In households that have pets or other animals, it will be necessary to periodically wipe down
the air intake grille on the unit to remove any animal hair that could block or restrict airflow.
CAUTION
DO NOT expose the filter to direct sunlight when allowing it to dry. This could cause the
filter to shrink.
DO NOT attempt to dry out the filter with fire or any other heat source.
DO NOT touch the metal parts of the unit when removing the filter. The sharp edges could
cut you.

NOTE: For filters that have collected excessive
amounts of dust, it may be necessary to use a soft
brush and neutral detergent to gently brush it
away. Once clean, allow to dry in a cool place.
