1.Cut or build a wall opening in the masonry wall similar to the frame construction (refer to the THRU-THE- WALL installation for a wall thickness greater than 8 1/2”)..

2.Secure the cabinet in place using masonry nails, or masonry anchor screws. Or, build a frame using the instructions found in the THRU-THE-WALL installation section.

3.Make sure the masonry above the cabinet is supported well. Use the existing holes in the cabinet or additional drilled holes to fasten the cabinet at various positions.

Make sure that the side louvers are clear of any ob- structions.

4.Install the exterior cabinet support brackets according to the SUPPORT BRACKET INSTALLATION instruc- tions in the THRU-THE-WALL installation section.

Caulk or flash with aluminum if needed. This will pro- vide a tight seal around the top and sides of the cabi- net.

5.For a more aesthetically pleasing installation, apply wood trim molding around the sides of the cabinet with- out obstructing the side louvers.

6.Install the chassis into the cabinet by following the steps described in the WINDOW MOUNTING section.

OPTIONAL: Caulking and installation of the trim on the interior wall may be done if desired. Caulk the openings around the top and sides of the cabinet and all sides of the wood sleeve to the opening.

NOTE: See the WINDOW MOUNTING instructions for the bottom rail seal location.
