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 L bracket 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

/4 inch distance between the

inner sill or the top of the first wood strip and the outer sill.

Stuff the sash seal between the glass and the
window to prevent air and insects from getting into
the room, as shown in Fig. 12.

b. Fasten the L bracket using a screw (TYPE A), as

showninFig.12.

6. a. Remove the screws that secure the cabinet and
base pan in the right side.

Fasten the support bracket (TYPE G) using a
removed screw. Attach the support bracket (TYPE G)
in the inner window sill with a screw (TYPE B), as
shown Fig. 13.

7. Window installation of room air conditioner is now

completed. See ELECTRICAL DATA for attaching
power cord to electrical outlet.

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. 14) Press the drain pipe
into the hole by pushing down and away from the fins
to avoid injury.

REMOVAL FROM WINDOW

Turn the air conditioner off, disconnect the power cord, remove the Support Bracket, 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. 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.

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 relay 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

■ The air conditioner is
unplugged.

■ Thefuseisblown/circuit
breaker is tripped.

■ Power failure.

■ Airflow is restricted.

■ TEMP Control set to a

higher number.

■ 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.

• 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.

• Set the TEMP Control to a lower number.

• Clean the filter at least every 2 weeks.

See the operating instructions section.

• When the air conditioner is first turned on
youneedtoallowtimefortheroomtocooldown.

• Check for open furnace floor registers
and cold air returns.

• Set the air conditioner's vent to the closed position.
