Panel and Thin Wall Application
1. Install the subbase as described in the subbase installa-
tion section.
2. Install the louver frame as described in the louver frame
installation section.
3. Position the room cabinet/wall sleeve in the louver frame
opening and on the subbase. The rear face of the cabinet
should be recessed from the outside edge of the louver
frame by the depth of the louver to be installed (Figure 7).
4. Remove the rectangular knockout in the base pan of the
wall sleeve.
5. Adjust the subbase leveling bolts so the room cabinet/
wall sleeve is level or tilted a maximum of
1
⁄
8
" (3mm)
downward to the outside. Secure the room cabinet/wall
sleeve to the subbase with the two long screws retained
from the subbase assembly (see Figure 4). Holes,
5
⁄
32
" in
diameter, have been added to each side of the room
cabinet/wall sleeve as a provision for securing the sleeve
in the wall opening. Each hole is located 2" (51mm) down
from the top and 2" (51mm) in from the rear of the sleeve.
These holes or other non-perforated locations in the sides
and/or top of the sleeve may be used to fasten the sleeve
to the wall from the inside. Never secure the room
cabinet/wall sleeve to the wall through the bottom.
6. Caulk the outdoor joint between the conditioner and wall
opening or louver frame around the top, bottom, and both
sides. Do not permit caulking to block weep holes.
Masonry and Thick Wall Application
Preparation of Wall Opening — In new construction, the
room cabinet/wall sleeve can be built into the building wall as
construction progresses, or openings can be left for later
installation. A lintel must be used to support any brick or
masonry work above the conditioner.
1. For installations with an optional subbase, install the
subbase as described in the subbase installation sec-
tion.
2. Set the room cabinet/wall sleeve in soft mortar and
position it in the wall opening. The rear face of the
conditioner should be recessed from the outside edge of
the wall opening by the depth of the louver to be installed
(see Figure 8). The center of gravity of the conditioner is
9
1
⁄
2
" (241mm) from the rear face. For wall mounted
conditioners, the center of gravity must be within the
load bearing portion of the wall; otherwise some method
of support is required.
3a. Installations without a subbase. Level or pitch the
room cabinet/wall sleeve a maximum of
1
⁄
8
" (3mm) down-
ward to the outside. Holes,
5
⁄
32
" in diameter, have been
added to each side of the room cabinet/wall sleeve as a
provision for securing the sleeve in the wall opening.
Each hole is located 2" (51mm) down from the top and
2" (51mm) in from the rear of the sleeve. These holes or
other non-perforated locations in the sides and/or top of
the sleeve may be used to fasten the sleeve to the wall
from the inside. Never secure the room cabinet/wall
sleeve to the wall through the bottom.
3b. Installations with an optional subbase. Adjust the
subbase leveling bolts such that the room cabinet/wall
sleeve is level or tilted a maximum of
1
⁄
8
" (3mm) down-
ward to the outside. Secure the room cabinet/wall sleeve
to the subbase with the two long screws retained from
the subbase assembly (see Figure 4). Holes,
5
⁄
32
" in
diameter, have been added to each side of the room
cabinet/wall sleeve as a provision for securing the sleeve
in the wall opening. Each hole is located 2" (51mm) down
from the top and 2" (51mm) in from the rear of the sleeve.
These holes or other non-perforated locations in the
sides and/or top of the sleeve may be used to fasten the
sleeve to the wall from the inside. Never secure the room
cabinet/wall sleeve to the wall through the bottom.
4. Caulk outdoor joint between conditioner and wall opening
around the top, bottom and both sides. Do not permit
caulking to block weep holes.
