Installation of Wall Sleeve
Considerations
The wall sleeve is a standard size 16" high, 42"
wide and 13
3
/
4
" deep. Slide channels are factory
welded into the sleeve to facilitate easy installation
and removal of the chassis. Each wall sleeve is
predrilled to match the mounting screws of the chassis.
Knockouts are provided for the optional external drain
kit used with the heat pump models.
All necessary fasteners are supplied to assemble the
chassis and the louver to the wall sleeve.
Wall Sleeve Extension for Thick Wall
Construction Types
The standard wall sleeve will accommodate a
maximum wall thickness described in table 1. For
thicker walls, wall sleeve extensions are required and
are available from your local representative. When
it is supplied by the representative, it is treated for
maximum corrosion resistance and matched to exact
size of the standard wall/sleeve. Be sure to provide
air splitters to prevent recirculation of condenser air.
Air splitters should be placed in the wall sleeve as
shown in figure 12. It is important that spacing of the
air splitters match exactly those dimensions shown in
figure 12.
Installation of Wall Sleeve Extension
Wall sleeve extensions are shipped in a separate
carton and tagged to match the proper unit. Be sure to
check tagging of the extension against that of the unit.
Install the wall sleeve extension as follows:
1. Position the extension with standard wall
sleeve so proper alignment with drain and
mounting holes is achieved.
2. Place a bead of caulk around the perimeter of the
wall sleeve and another bead around the mating
side of the wall sleeve extension so that the joint is
watertight. Be sure to use a resilient caulking such
as silicone.
3. Assemble the wall sleeve extension to the wall
sleeve. Clean out weep holes to assure proper
drainage.

4. Attach indoor drain kit (if used) according to the
instructions on page 10. Outdoor drain kits must
be installed after wall sleeve is in place.
5. Continue wall sleeve installation according to
instruction #4 on page 12.
Installation of Louver Frame for Thin Wall
Construction Types
Louver frames should be used for panel wall and
thin wall applications to assure positive anchoring to
the wall. Recess the wall sleeve so that the louver is
flush with the outside of the building. Place louver
frame around wall sleeve as shown in figure 13. Secure
angles at side and top of walls.
CAUTION
DO NOT drill holes in the bottom of the wall sleeve as it
will cause leaks.
