Perfect Aire PAC15000 - Manual (Page 18)

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.
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 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.
