READ BEFORE INSTALLING UNIT
To avoid risk of personal injury, property damage, or product damage due to the weight of this device and sharp
edges that may be exposed:
Air conditioners covered in this manual pose an excessive weight hazard. Two or more people are needed to
move and install the unit. To prevent injury or strain, use proper lifting and carrying techniques when moving unit.
Carefully inspect location where air conditioner will be installed. Be sure it will support the weight of the unit over
an extended period of time.
Handle air conditioner with care. Wear protective gloves whenever lifting or carrying the unit. AVOID the sharp
metal fins of front and rear coils.
Make sure air conditioner does not fall during installation.
If a new electrical outlet is required, have the outlet installed by a qualified electrician before installing unit.
NOTE: DO NOT USE ANY SCREWS OTHER THAN THOSE SPECIFIED HERE.
Preliminary instructions: window sash seal
Do the following before starting to install unit. See illustrations below.
Check dimensions of your unit to determine model type:
Heavy duty Medium
Capacity: 22,000~28,500 BTU 15,000~18,500 BTU
Unit Height: 18-5/8" 17-5/8"

Min. Window Width: 31" 26-1/2"
Max. Window Width: 42" 40-1/2"
1. Check window opening size: the mounting parts
furnished with this air conditioner are made to install in
a wooden sill double=hung window. The standard parts
are for window dimensions listed above. Open sash to
a minimum of 19" (483mm). (FIG.l)
2. Check condition of window: all wood parts of window
must be in good shape and able to firmly hold the needed
screws. If not, make repairs before installing unit.
3. Check your storm windows: If your storm window
frame does not allow the clearance required, correct by
adding a piece of wood as shown (FIG.2), or by removing
storm window while room air conditioner is being installed.

4. Check for anything that could block airflow
Check area outside of window for things such as shrubs, trees, or awnings. Inside, be sure furniture, drapes, or blinds
will not stop proper air flow.
5. Check the available electrical service
Power supply must be the same as that shown on the unit serial
nameplate. (See Use & Care Guide for serial plate location.) Power
cord is 48" long. Be sure you have an outlet near.
All models have a 3-prong service plug to provide proper service and
safe positive grouding. Do not change plug in any way. Do not use an
adapter plug. If your present wall outlet does not match your plug, call
a qualified electrician to make the needed change.
6. Carefully unpack air conditioner
Remove all packing material. Protect floor or other stable flat surface
with covering to prevent scratches from unit. With the aid of an
assistant, remove unit from styrofoam base and rest on protected
surface. Move and install unit with the aid of an assistant. Save
packing and shipping box for future unit storage.

Thru=The-Wall installation
® Consult local building codes prior to installation, or a qualified carpenter.
Select Wall Location
This air conditioner slides out from its cabinet, so that it can be installed through an outside wall as explained
below.
Heavy duty Medium
Max wall thickness 10" 8"
o
@
iMPORTANT: Side louvers must never be blocked.
All parts needed for Thru=The=Wall Installation 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, and 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 to the area to be cooled, and it is not blocked.
5. Allows unblocked airflow from rear sides and end (outside) of installed air conditioner.
Prepare Wall
1. Prepare wall in frame construction (including brick and stucco veneer). Working from inside the room, find wall stud
nearest the center of area where air conditioner will be installed (by sounding wall, or by magnetically finding nails).
2. Cut out a hole on each side of center stud.
3. Measure between inside edges of every other stud as shown in FIG.1. Carefully measure and cut an opening with
the following dimensions depending on your model. See FIG.1 and FIG.2.
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.

Prepare and Install Cabinet
1. Slide air conditioner from cabinet; refer back to Step 1 of Window Mounting.
2. Place cabinet into opening with bottom rail resting firmly on bottom board of wooden frame.
3. Position cabinet to achieve proper downward tilt for water removal. Unit must tilt back 5/16" to 3/8" for proper water
drainage. (See FIG.5 below.)
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.6 following)

Refer to Step 5 of Window Mounting for assembly of support brackets. Nail a wooden strip to the outside wall for the
angle sill bracket to rest upon. See Fig. 7.
5. Screw or nail cabinet to wooden frame using shims as needed to eliminate cabinet distortion. See Fig. 8. Remember
to maintain proper tilt as described in Step 3.

6. Install air conditioner into cabinet by following all steps in Step 9 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 opendings around top and sides of cabinet, and all sides of wood sleeve to the
opening.
® See Step 5, Item 4 of Window Mounting Instructions for bottom rail seal location.
Masonry Construction
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 secure cabinet is
to build a frame in the masonry wall such as the one shown in Fig. 3 of Step 2 Prepare Wall. Securely anchor frame to
masonry wall. This way 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 additions holes
can be drilled to fasten cabinet at various positions. Be sure that side louver clearance is in accordance with Step 1
Select Wall Location.
4. Install exterior cabinet support brackets as shown in Step 3 of Thru-the-Wall Installation. Caulk or flash if needed, to
provide a weather-tight seal around top and sides of cabinet.
5. To complete installation, apply wood trim molding around room side projection of cabinet.
