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.
About the Controls on the Air Conditioner
• 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.

Additional controls and important information.
Air Direction
• ADJUSTING THE AIR DIRECTION USING THE HORIZONTAL AIR-DEFLECTOR CONTROL
Using the control tabs, the air flow can be directed
to the left, right, straight ahead, or any combination
of these directions.
Care and Maintenance
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.
About the Controls on the Air Conditioner
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.
Do not force open
or open too
far (about 56°)
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)

Window Requirements
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 1
the center of the outer sill flush against the back off the inner sill. This will raise the L bracket 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.

Troubleshooting Tips save time and money!
Review the chart below first and you may not need to call for service.
Normal Operation
• 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.
Abnormal Operation
Problem Possible Causes What To Do
Air conditioner
does not start
Air conditioner
does not cool as it
should
Air conditioner
freezing up
■
The air conditioner is
unplugged.
■
The fuse is blown/circuit
breaker is tripped.
■
Power failure.
■
Airflow is restricted.
■
The THERMOSTAT may
not be set high enough.
■
The air filter is dirty.
■
The room may have been
hot.
■
Cold air is escaping.
■
Cooling coils have iced up.
■
Ice blocks the air flow and
stops the air conditioner
from cooling the room.
• Make sure the air conditioner plug is pushed
completely into the outlet.
• Check the house fuse/circuit breaker box and
replace the fuse or reset the breaker.
• If power failure occurs, turn the mode control to Off.
When power is restored, wait 3 minutes to restart the
air conditioner to prevent tripping of the compressor
overload.
• Make sure there are no curtains, blinds, or furniture
blocking the front of the air conditioner.
• Turn the knob to a higher number. The highest
setting provides maximum cooling.
• Clean the filter at least every 2 weeks.
See the care and Maintenance section.
• When the air conditioner is first turned on, you need
to allow time for the room to cool down.
• Check for open furnace floor registers and cold air
returns.
• See Air Conditioner Freezing Up below.
• Set the mode control at High Fan or High Cool with
thermostat at 1 or 2.
