Installing in a sliding window
1. Attach support brece to platform as shown.
Use the adjustment bolt and hex flange nut to
complete the assembly. Choose the slot and
adjustment bott hole locations that will create a
45’ angle between the platform and the
support brace. Try the assembly in the window
to determine if the platform will rest properly
and allow the proper slope (?&inch lower on
outside). Without the proper slope, water could
drip into your home and cause water damage.
NOTE: lf you are planning to use a siding-
protection board (see Step 5) on the outside of
your house, hold the board in place when
testing the assembly in the window.

2. Men~re and lightly mark e line 8VAnches
from the right window jamb.
NOTE: lf any sash stop protrudes more than
1 inch from the side window jambs, the
8W4nch measurement must be increased
accordingly. Screen and storm window frames
may also require adjustments to the measure-
ment.
3. Center the platform ueembfy on the line
with the inside platform tab pressed against
the inside edge of the window track. Using the
holes in the platform as a guide, mark and drill
two !&-inch diameter holes. Drill holes in
either track or stool.
Proper Dammge Hazard
Be sure the wood stool or window track is
securely attached to the building construc-
tion. Use longer screws into the sub-
framing ff necessary.
Failure to follow the above precaution could
result in damage to the window or air
conditioner.
4. Peel off the protecthro backing from the
track seal. Apply seal to the room side of the
window track. The center of the seal strip
should coincide with the line marked in Step 2.
The two screw holes drilled in Step 3 should
be directly above the seal strip in the inner
track
5. Securely attach a riding-protection board
to the side of the house.
OR
To avoid permanent siding damage, attach the
siding-protection board to the base of the
support brace as shown.

moved.
Failure to follow the above precautions could
result in electrical shock or personal injury.
NOTE: If you turn your air conditioner off or if
the compressor turns off when lowering the
Thermostat Control, wait at least 3 minutes
before turning it back on. Doing this keeps the
air conditioner from blowing a fuse or tripping a
circuit breaker.
17

Using the exhaust vent control
The Exhaust Vent Control draws stale or smoky
air from the room or circulates existing rmrn air.
To exhauot room air:

NOTE: For maximum performance, the Exhaust
Vent Control must be in the CLOSED position
when cooling or room air circulation is desired.
Cooling at low outside temperatures
When the outside temperature drops below 70°F
and the air conditioner is cooling, frost may form
on the coils behind the air intake panel. This will
block the airflow into the room.
To defrost the coik:
l Set the Fan Control to the FAN ONLY setting
and allow unit to run until frost is gone.
To prevent frost build-up:
1. Set the Fan Control to desired COOL setting.
2. Set Thermostat Control to the middle setting.
3. Make sure all louvers are open.
18

Adjusting the air direction louvers
The air direction louvers control the airflow
direction. Your air conditioner can direct the
airflow in 4 directions - up, down, left or right.
To direct airflow up or down:
l Tilt the louvers up or down with the tabs located
at the outside edges of the louvers.
To direct airflow left or right:
l Turn thumb wheel to the left or right for desired
airflow.
NOTE: The tabs and thumb wheels can be
adjusted separately for a variety of airflow
combinations.
