Masonry and Thick Wall Applications
1. Preparation of the wall opening — In new construc-
tion, the room cabinet/wall sleeve can be built into
the building wall as it progresses, or openings can
be left for later installation.
A lintel by others must be used to support any brick
or masonry work above the conditioner.
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. When using the flanged stamped
louver, the rear flange of the room cabinet/wall
sleeve will be flush with outside edge of the wall
opening. The center of gravity of the conditioner is
⁄ " from the rear face. For wall-mounted condi-

tioners, the center of gravity must be within the
load bearing portion of the wall; otherwise, sup-
port is required.
3. Level the room cabinet/wall sleeve side to side and
pitch down 1/4 bubble to outside. Securely fas-
ten the room cabinet/wall sleeve in the wall from
inside the cabinet through the sides and/or top on
the outdoor side of the weather seal. Make sure
the cabinet is not distorted. Never secure through
the bottom of the cabinet. For installations using
a subbase, level the room cabinet/wall sleeve with
leveling bolts provided with the subbase. Attach
the subbase to the room cabinet/wall sleeve per
instructions provided with the subbase.
4. After the room cabinet/wall sleeve is installed and
leveled side to side and pitched down 1/4 bubble
to the outside, secure it and the louver frame to the
wall with screws driven through the sides and top
of the room cabinet/wall sleeve outward through
the louver frame. Never secure the frame through
the bottom, as it may cause leaks. A
hole has been added to each side of the wall sleeve
as a provision for securing the sleeve in the wall
opening. Each hole is located 2" down from the
top and 2" in from the rear of the sleeve. (See Fig-
ures 12 and 13.)
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.
5. Caulk the outdoor joint between the room cabinet/
wall sleeve and the wall opening (or louver frame):
top, bottom and both sides. Do not permit caulking
to block the weep holes.
