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.
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-
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 2x4’
s 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 cabient support brackets as shown in
Step 2 of Thru-the-Wall Installation. Caulk or flash if
neede, 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.
