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°)

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.

C. HOW TO SECURE THE DRAIN PIPE

In humid weather, excess water may cause the BASE

PAN to overflow. To drain the water, remove the

DRAIN CAP and secure the DRAIN PIPE to the rear

hole of the BASE PAN. (Fig. 13)

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.
