About the Controls on the Air Conditioner
TURN THE AIR CONDITIONER OFF AND REMOVE THE PLUG FROM THE POWER OUTLET.
• TO CLEAN FILTER
The air filter will become dirty as it removes
dust from the inside air.
It should be washed at least every 2 weeks.
If the air filter remains full of dust, the air
flow will decrease and the cooling capacity
will be reduced, possibly damaging the unit.
1. Pull the inlet grille forward and pull out the
air filter. (Fig. 1)
2. Wash the air filter in warm 104°F(40°C) water.
Be sure to shake off all the water before
replacing the filter.
• CLEANING THE AIR CONDITIONER
The front grille and inlet grille may be wiped with a
cloth dampened in a mild detergent solution. (Fig. 2)
The cabinet may be washed with mild soap or
detergent and lukewarm water, then polished with
a liquid wax used for appliances.
To ensure continued peak efficiency, the condenser
coils (outside of unit) should be checked
periodically and cleaned if clogged with soot or
dirt from the atmosphere.
• HOW TO REMOVE THE FRONT GRILLE
1. Pull the inlet grille forward.
2. Remove the screw securing the front grille. (Fig. 3)
3. Push the grille up from the bottom and pull
the top of the grille away from the case as
the top tabs lift out of their slots. (Fig. 4)
Do not force open
or open too
far (about 56°)

1. This unit is designed for installation in standard double hung windows with actual opening widths of
22 to 36. The upper and lower sash must open sufficiently to allow a clear vertical opening of 13
from the bottom of the sash to the window stool.
2.If a storm window presents interference, fasten a 2 wide wood strip to the inner window sill across
the full width of the sill. The wood strip should be thick enough to raise the height of the window sill
so that the unit can be installed without interference by the storm window frame. 
See Fig. 5-2. The top of the wood strip should be approximately 
3/4 higher than the storm window
frame (STORM WINDOW FRAME) or wood strip (OUTDOORS) to help condensation to drain
properly to the outside.
3. Install a second wood strip (approximately 18 long by 1
1/2 wide and same thickness as first strip)
in the center of the outer sill flush against the back off the inner sill. This will raise the Lbracket as
shown in Fig. 5-2. 
4. The thickness of the second wood strip may not be the same as the first wood strip. 
The thickness of the second wood strip must be defined to keep the 
3/4inch distance between the
inner sill or the top of the first wood strip and the outer sill.
