Thru-The-Wall Installation
NOTE: Consult local building codes prior to installation,
or a qualified carpenter.
Select Wall Location
This air conditioner has a slide-out chassis, so it canbe installed
through an outside wall up to 12" thick. IMPORTANT: Side
louvers must never be blocked.
NOTE: All parts neede 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. Paces, and is not blocked to the area to be cooled.
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 inding
nails).
2. Cut or knock out a hole on each side of center stud.
3. Measure between inside edges ofeve_T other stud as shown
in FIG. 1.
Carefully measure and cut an opening with t he following
dimensions. See FIGS. 1 and 2.
WIDTH "X" = 26-3/4" (67.9cm) plus twice the thickness
of framing material used.
HEIGHT "Y" = 18-7/8" (47.9cm) plus twice the
thickness of fiaming material used.
FIG. 2
Y
UP TO
8-1/2"
4. Build a wooden sleeve with the INSIDE dimensions of
26-3/4" (67.9cm) in width and 18-7/8" (47.9cm) in height.
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 to spacers with front flush with
drywall.

NOTE: If wall thickness is 8-1/2" or more, add aluminum
flashing over bottom of frame opening to assure no water can
enter area between inner and outer wall.

Prepare and Install
Cabinet
I. Slide chassis from cabinet. Refer back to Step l 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 slope for water removal.
(See FIG. 1 below.)

Refer to Step 4 of Window Mounting for assembly of support
brackets. A wooden strip nailed to the outside wall should be
used in coniunction with sill support angle brackets.

5. Screw or nail cabinet wooden frame using shims if frame
is oversized, to eliminate distortion. Remember to maintain
proper slope as described in Step 3.

4. Secure bottom rail to wood frame with two large wood
screws 1"(2.5 cm) long using the tow holes in the bottom
of the channel resting on frame. (See FIG. 2 following)
6. Install chassis into cabinet by following all steps in Step
8 of Window Mounting. (continued)
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 ofwtx_d sleeve to the opening.
NOTE: See Step 7, Item 3 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 Tbau-the-
Wall Installation for a wall thickness _eater than 8-1/
2").
2. Secure cabinet in place using masom 7 nails, or the right
masom 7 anchor screws. (Another way to do this is to build
an in-between frame of 2x4's as shown in the Step 2 Prepare
Wall illustrations-but make it double framed on either
side, and install between n_soru 7 wall opening and cabinet.
Frame must be securely anchored to masom 7 wall
opening) This way gives very good louver clearance on
either side of cabinet.
3. Install a lintel to support masom 7 wall above cabinet.
Existing holes in cabinet can be used and/or additional
holes can be &illed to fasten cabinet at various positions.
Be sure that side louver clearance is in accordance with
Step 1 above.
4. Install exterior cabient support brackets as shown in
Step 2 of Tinu-the-Wall Installation. Caulk or flash if
nee&, to provide a wether-tight seal around top and
sides of cabinet.
5. To complete installation, apply wood trim molding
around room side projection of cabinet.
