NOTE: If the wall thickness is 8½" (21.59 cm) or more, add
aluminum flashing over the bottom of the frame opening to
assure water is unable to enter the area between the inner
and outer wall.

Prepare and Install the Cabinet
1.
Remove chassis
Slide the chassis from the cabinet. See the "Prepare Air
Conditioner for Installation" section for more details.
2.
Place and position cabinet
Gap size 5/16"
to 3/8"
Place the cabinet into the opening with the bottom channel
resting firmly on the bottom rail of the wood frame. Position
the cabinet so it is properly tilted for water removal.
3.
Secure bottom channel to frame
Secure the bottom channel to the wood frame with two large
1" (2.5 cm) wood screws.
Caulk as
needed
4.
Place and position cabinet
Assemble brackets. See "Install Support Brackets" in the
"Window Installation" section. Nail a wooden strip to the
outside wall to be used in conjunction with the angled sill
support brackets.
5.
Secure cabinet and install chassis
Screw or nail the cabinet to the wooden frame using shims if
the frame is oversized to eliminate possible noise. Remember
to maintain proper slope for water elimination.
Reinstall the chassis into the cabinet. See the "Install the Chassis
into the Cabinet" section.
Masonry Construction
1. Cut or build a wall opening in the masonry wall similar to the
frame contruction. See the "Wall Installation Instructions –
240 V Models" section for a wall thickness greater than 8½"
(21.59 cm).
2. Secure the cabinet in place using masonry nails or masonry
anchor screws. Or build a frame using the instructions found
in the "Wall Installation Instructions – 240 V Models" 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 obstructions.
4. Install the exterior cabinet support brackets according to
"Prepare and Install the Cabinet" in the "Wall Installation
Instructions – 240 V Models" section. Caulk or flash with
aluminum if needed. This will provide a tight seal around
the top and sides of the cabinet.
5. For a more aesthetically pleasing installation, apply wood trim
molding around the sides of the cabinet without obstructing
the side louvers.
