INSTALLATION INSTRUCTIONS
6. Install chassis into cabinet by following all
steps in Step 8 of Window Mounting.
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.
3.
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.
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.)
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.
C.Masonry Construction
5. Screw or nail cabinet wooden frame using
shims if frame is oversized to eliminate
distortion. See Fig.8.Remember to maintain
proper slope as described in Step 3.

OPTIONAL:
Caulking and installation of trim on

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.
