Installation Instructions
For A-Kit 22"
Please read ALL instructions before installing. Two
people are recommended to install this product. If
a new electrical outlet is required, have the outlet
installed by a qualified electrician before installing
unit. See #5 in Preliminary Instructions following.
Preliminary Instructions
Do the following before starting to install unit.
See illustrations below.
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 a window
opening of 30" (711 mm) minimum to 42"
(1067 mm) maximum width. Open sash to a
minimum of 19" (483 mm). (FIG. 1)
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 - you will need
1/2" (13 mm) clearance below window stool.
If storm window frame does not allow the
clearance required, correct by adding a piece
of wood as shown in FIG. 2, or by removing
storm window while room air conditioner is
being installed. (continued)

provide proper service and safe positive
grounding. 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.

Thru-The-Wall Installation
NOTE: Consult local building codes prior to
installation, or a qualified carpenter.
Location
This air conditioner has a slide-out chassis, so it
can be installed through an outside wall up to
7" (178 mm) thick. IMPORTANT: Side louvers
must never be blocked.
NOTE: All parts needed for Thru-The-WaU
Installation are provided, except a wood frame,
shims, and 10 wood screws (#10-1" long minimum
(25 mm)). 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, and is not blocked to the area to be
cooled.
5. allows unblocked airflow from rear sides and
end (outside) of installed air conditioner.
pare 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 or knock 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. See FIGS. 1 and 2.
WIDTH "X" = 24-1/4" plus twice the
thickness of framing material used.
HEIGHT "Y" = 15-1/4" plus twice the
thickness of framing material used.

4. Build a wooden sleeve with the INSIDE
dimensions of 24-1/4" in width and 15-1/4" 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 with front flush with
drywall.

NOTE: If wall thickness is 7" (178 mm) or more,
add aluminum flashing over bottom of frame

between inner and outer wall.

Refer to Step 4 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.
FIG. 2
1. Slide chassis 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 slope for
water removal. (See FIG. 1 below.)

.
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. 2 following.)
6. Install chassis into cabinet by following all
steps in Step 8 of Window Mounting.

OPTIONAL:Caulkingandinstallationof trim on
interior wall maybe done.Youcanbuywood
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.
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 Thru-the-WaU Installation for a wall
thickness greater than 8-1/2").
.
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 2x4's (51 mm x 102 mm) as shown in the
Step 2 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 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 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 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.
