(i.e. the higher number the greater cooling)
. FOR NORMAL COOLING
1_Turn the Operation Knob to the High Cool from the Low Coo] setting,
2. Set the Thermostat control to the desired temperature mark _ (the mido_int is a good starting position). If

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_(40°C) water.
Be sure to shake off all the water before
replacing the filter.
Do not:force
open or open to

• 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
Liquid Wax for Appliances_
To ensure continued peak efficiency, the _ndenser
coils(outside of unit) should be checked
periodically and cleaned if clogged with soot or
dirt from the atmosphere.
Fig. 2
• HOW TO REMOVE THE FRONT GRILLE
1. Remove the thermostat knob and the operation
knob by pulling.
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. 3)

Preparing the unit for Installation
NOTE: All supporting pars should be s_ured to firm 'wood, masonry, or metal.
1+This unit is designed for installation in standard double hung windows with actual opening widths
of 22" to 36L The upper and lower sash must open sufficiently to allow a ciear vertical opening of
14" from the bottom of the saslh to the window stool.(Fig. 4-2)
2Jr a storm window presents interference, fasten a 2" wide wood strip (OUTER SILL) to inner window
sill across the full width of the sit!. 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. 4-2. Top of wood strip should be approximately 314"higher than the storm window frame
(STORM WINDOW FRAME) or wood strip (OUTDOORS) to help condensation drain properly to
the outside.
3. Install a s_ond wood strip (approximately 6" long 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 "L" bracket as
shown Fig. 4-2.
4. If the distance between the STORM WINDOW FRAME and WOOD STRIP MOUNTED ON TOP
OF iNNER SiLL is more than 1", two of w_d strips are not necessary.
WOOD STRIP MOUNTED 1" MAX.

Troubleshooting Tips
Save time and money! Review the cha_ below first and
you may not need to carl for service.
Normal Operating
*You may hear a pinging noise caused by water being picked up and thrown against the condenser
on rainy days or when the humidity is high. This design feature helps remove moisture and improve
efficiency.
,You may hear the thermostat click when the compressor cycles on and off.
, Water will collect in the base pan during high humidity or on rainy days. The water may overflow
and drip from the outdoor side of the unit
, The fan may run even when the compressor does not.
