functions, then follow the symbol for the functions you desire. The unit can be controlled by the unit
control alone or with the remote.
COOL MODE
The desired cool setting is selected by rotating the knob to the right
to the desired position.
HIGH COOL has maximum cooling e ect and air ow.
LOW COOL has minimum cooling e ect and air ow.
FAN MODE
Rotate the knob to the left to select your choice of fan speeds for air
circulation.
NOTE: When selecting a fan speed, the compressor will not run.
THERMOSTAT
The thermostat is used to set the desired room temperature when

To set the desired room temperature, rotate the thermostat switch
to the desired setting. After the set temperature is achieved the
thermostat will automatically start and stop the compressor in
order to maintain the desired set temperature.
Rotate the thermostat selector clockwise for higher cool settings.
Higher cool settings will provide lower room temperature. Rotate
the thermostat selector counter clockwise for lower cool settings.
Lower cool settings will provide higher room temperature.

9 Install Chassis into Cabinet and Install Front to Unit
1. Lift air conditioner and carefully slide into cabinet leaving 6” protruding.
2. DO NOT press or apply pressure to controls or nned coils.
3. Be sure chassis is firmly seated towards rear of cabinet.
4. Installation of front is the reverse of removal outlined in Section 1.
1 Select Wall Location
The air conditioner has a slide-out chassis, so that it can be installed through an outside wall as
specified below:
Max. Wall thickness: 12” or 10”
IMPORTANT: Side louvers must never be blocked.
NOTE
Consult local building codes prior to Installation, or a qualified carpenter.
NOTE
All parts needed for Thru-The-Wall Installtion are provided, except a wood frame, shims, and 10 wood
screws (#10-1” long minimum).
Select a wall surface that:
1. Does not support major structural loads such as the frame construction at ends of windows, under
truss-bearing points, etc.
2. Does not have plumbing or wiring inside.
3. Is near existing electrical outlets, or where another outlet can be installed.
4. Faces, and is not cut o from the area to be cooled.
5. Allows unblocked air ow from rear sides and end (outside) of installed air conditioner.
B. Thru-the Wall Installation
3-3/8" MIN
(8.6 cm)
2 Prepare Wall
1. Prepare wall in frame construction (including brick and stucco
veneer). Working from inside the room, locate wall stud nearest
the center of area where air conditioner will be installed.
2. Cut or knock out a hole on each side of center stud.
3. Measure between inside edges of every other stud as shown
in Fig. 20.

See Fig. 20 and Fig. 21.
WIDTH X = inside model width plus twice the thickness of framing
material used.
HEIGHT Y = inside model height plus twice the thickness of framing
material used.
Inside Frame Height: 18-7/8” (47.9 cm) or 18” (45.7 cm)
Inside Frame Width: 26-3/4” (67.9 cm) or 23-7/8” (60.6 cm)
4. Build a wooden frame with the INSIDE dimensions of your model
listed above. (remember to measure twice). Frame depth should
be the same as wall thickness. Fill in the space from the opening
to the studs with wood spacers, as shown.
5. Nail frame to spacers with front ush to drywall.
NOTE
If wall thickness is 8-1/2” or more, add aluminum ashing over
bottom of frame opening to assure no water can enter area
between inner and outer wall.
3 Prepare and Install Cabinet
1. Slide chassis from cabinet. Refer back to Step one of Window
Mounting.
2. Place cabinet into opening with bottom rail resting rmly on
bottom board of wooden frame.
3. Position cabinet to achieve proper slope for water run off.
(See Fig. 24).
4. Secure bottom rail to wood frame with two large wood screws
1” (2.5 cm) long using the two holes in the bottom of the
channel resting on frame. (See Fig. 25).

Check that air conditioner is tilted back about 1-1/4” to 1-5/8”
(tilted about 3° to 4° downward to the outside). After proper
installation, condensate should not drain from the over ow drain
hole during normal use. Adjust the slope if otherwise. (Fig. 15).
NOTE
See Step 5, Item 3 of Window Mounting Instructions for
bottom rail seal location.
1. Cut or build a wall opening in the masonry wall similar to the frame construction (refer to Step 2 of
Thru-the-wall Installation for a wall thickness greater than 8-1/2”).
2. Secure cabinet in place using masonry nails, or the right masonry anchor screws. (Another way to
do this is to build an in-between frame of 2x4s as shown in the Step 2 of Prepare Wall illustrations,
but make it double framed on either side, and install between masonry wall opening and cabinet.
Frame must be securely anchored to masonry wall opening). This method gives very good louver
clearance on either side of cabinet.
3. Install a lintel to support masonry wall above cabinet. Existing holes in cabinet can be used and/
or additional holes can be drilled to fasten cabinet at various positions. Be sure that side louver
clearance is in accordance with Step 1 above.
4. Install exterior cabinet support brackets as shown in Step 2 of Thru-the-wall installation. Caulk or
ash if needed, to provide a weathertight seal around top and sides of cabinet.
5. To complete installation, apply wood trim molding around room side projection of cabinet.
1” Long Wood
Screw
Fig. 25
Refer to Step 5 of Window Mounting for assembly of support
brackets. A wooden strip nailed to the outside wall should be used
in conjunction with sill support angle brackets.
5. Screw or nail cabinet wooden frame using shims if frame is
oversized, to minimize distortion. See Fig. 27. Remember to
maintain proper slop as described in Step 3.
6. Install chassis into slope cabinet by following all steps in Step 8
of Window Mounting.
OPTIONAL: Caulking and installation of trim on interior wall may
be done. You can buy wood from your local lumber or hardware
supply. On the outside, caulk openings around top and sides of
cabinet, and all sides of wood sleeve to the opening.
