Figure 2-35.
Refer to Install Support Bracket for assembly of
support brackets. A wooden strip nailed to the
outside wall should be used in conjunction with sill
support angle brackets. (See Figure 2-34)
5. Screw or nail cabinet wooden frame, using shims if
frame is oversized to eliminate distortion. Remember
to maintain proper slope of air conditioner.
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.
Masonry Construction
1. Cut or build a wall opening in the masonry wall
similar to the frame construction (refer to Thru-the-
Wall Installation for a wall thickness greater than
8-½ inches).
2. Secure cabinet in place using masonry nails, or the
correct masonry anchor screws. (Another way to
do this is to build an in-between frame of 2X4’s as
shown in 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 linted 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.
