Wall Sleeve Installation – Medium Thick Wall Construction
A heavy-gauge, corrosion-resistant wall sleeve is provided for each unit. The wall sleeve is either shipped in a separate carton or
shipped in a multi-pack of 15 on a skid.
The standard wall sleeve is designed to be easily installed in a
variety of wall constructions.
Note: The center of gravity is 10
edge of the wall sleeve. The center of gravity must
be within the load-bearing surface of the wall or other
support must be employed.
Support can be from a factory-supplied subbase or
from other field-supplied materials. (265V always
requires a subbase.) It may also be floor mounted
for 208/230V.
!
WARNING
Failure to provide proper support can result in property
damage and severe personal injury.
Leave enough space for the cord to exit from under the front
panel if required. The wall sleeve is not intended to replace
the lintel. Install as follows:
1.
Clean the opening of all debris that may interfere with
installation.
2.
If the unit is to be supplied with a subbase, refer to page
8 for installation procedure. Install subbase and wall sleeve
at the same time. (Subbase is required for 265V but is
optional for 208/230V.) A minimum of 4
must project into the room when using a subbase.

3.
If the optional drain kit is to be employed (heat pumps
only), refer to page 7 before proceeding.
4.
Place a thin pad of mastic on bottom of the opening and
slide in the wall sleeve. Be sure to recess the wall sleeve
enough to accommodate outside louvers. This recess is
3/8˝ for stamped louvers and 1
vers. Louver should be flush to exterior surface when
complete.
Note: Wall sleeve must be flush with the exterior wall,
if using the outdoor drain kit (see page 7).
5.
Level wall sleeve left to right, pitch it 1/4" bubble to the
outdoors and secure in wall with fasteners (as shown in
Figure C, page 12). A 5/16˝ hole is provided on each side,
2˝ down from the top and 2˝ in from the rear. Additional
holes may be required to firmly secure the wall sleeve.
Do not drill holes in the bottom of the wall sleeve as it
may cause leakage.
Where a subbase is used, secure the wall sleeve to the
subbase with clips provided (see subbase installation,
page 8).
6.
Caulk the wall sleeve to the wall opening on both inside
and outside perimeter. Be careful not to plug the weep
holes. Caulking should be a resilient, non-hardening type,
such as silicone.
