Installation
Instructions
NOTE
Check that air conditioner is tilted back about 1-1/4” to 1-5/8”
(tilted about 3° to 4° downward to the outside). After proper
installation, condensate should not drain from the over ow drain
hole during normal use. Adjust the slope if otherwise. (Fig. 15).
NOTE
See Step 5, 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 2x4s as shown in the Step 2 of 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 method 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
ash if needed, to provide a weathertight seal around top and sides of cabinet.
5. To complete installation, apply wood trim molding around room side projection of cabinet.

Refer to Step 5 of Window Mounting for assembly of support
brackets. A wooden strip nailed to the outside wall should be used
in conjunction with sill support angle brackets.
5. Screw or nail cabinet wooden frame using shims if frame is
oversized, to minimize distortion. See Fig. 27. Remember to
maintain proper slop as described in Step 3.
6. Install chassis into slope cabinet by following all steps in Step 8
of Window Mounting.
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.
