About the Controls on the Air Conditioner
The controls will look like one of the following:
Controls
Off - Turns air conditioner off.
High Fan - High speed fan operation without cooling.
Low Fan - Low speed fan operation without cooling.
High Cool - Cooling with high speed fan operation.
Low Cool - Cooling with low speed fan operation.
This automatically controls the temperature of the indoor air.
Turn the knob so that arrow points to the larger marks for
greater cooling.
Point the arrow to the smaller marks for more moderate
cooling.
(i.e. the higher the number, the greater the cooling)
• FOR NORMAL COOLING
1. Turn the operation switch to the High Cool or the Low Cool setting.
2. Set the thermostat control to the desired temperature mark (the mid-point is a good
starting position). If the room temperature is not satisfactory after a reasonable time,
adjust the control to a cooler or warmer setting, as appropriate.
• FOR MAXIMUM COOLING
1. Turn the operation switch to the High Cool setting.
2. Set the thermostat control to the largest temperature mark.
• FOR QUIETER OPERATION
1. Turn the operation switch to the Low Cool setting.
2. Set the thermostat control as needed.
• CAUTION
When the air conditioner has performed its cooling operation and is turned off or set to the fan
position, wait at least 3 minutes before resetting to the cooling operation again.

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
Liquid Wax 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. 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. 4)
Do not force open
or open too
far (about 56°)

NOTE: All supporting parts should be secured 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 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 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. Top of 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 6" long by 11/2" 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 Fig. 5-2.
4. If the distance between STORM WINDOW FRAME and WOOD STRIP MOUNTED ON TOP OF
INNER SILL is more than 1", two of wood strips are not necessary.

DRAIN CAP and secure the DRAIN PIPE to the rear
hole of the BASE PAN. (Fig. 13)
REMOVAL FROM WINDOW
Turn the air conditioner off, disconnect the power cord, remove the "L" bracket and the screws installed
through the top and bottom of the guide panels, and save for reinstallation later. Close the guide panels.
Keeping a firm grip on the air conditioner, raise the sash, and carefully tilt the air conditioner backward,
draining any condensate water. Lift the air conditioner from the window and remove the sash seal from
between the windows.
USE OF EXTENSION CORDS
Because of potential safety hazards, we strongly discourage the use of an extension cord. However, if you wish to
use an extension cord, use a CSA certified/UL-listed 3-wire (grounding) extension cord, rated 15A, 125V.
