Preparing Unit for Installation
Note: first install the louver frame following steps 1
and 2 as described in "Louver Frame Installation."
Remove the outer carton and inspect the conditioner
for damage. Report any damage found to the carrier.
Note: Save the outer carton for reuse to cover the
installed conditioner until ready for use.
Louver Frame Installation
When a louver frame is used, it must be installed
prior to, or at the same time, as the room cabinet/wall
sleeve, and it must be level and square (see Figure 8).
1. Apply caulking compound on the surfaces of the
louver frame's four flanges which will come in
contact with the wall. Add caulking as required for
weather tight seal.
2. Insert the sleeve of the louver frame into the wall
opening from the exterior of the building and apply
firm pressure so that the caulked frame flanges are
snug against the exterior of the building. Secure
the louver frame to the wall if desired.
3. Secure the louver frame to the wall through the
sides and top. Never secure the frame through the
bottom as it may cause leaks.
If the louver frame is to be installed in a panel wall,
it should be installed at the same time as the room cabi-
net/wall sleeve.

Cabinet/Wall Sleeve Extension for Thick Wall
Construction Types
The standard wall sleeve will accommodate a
maximum wall thickness of 10.25." 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 9. It is
important that spacing of the air splitters match exactly
those dimensions shown in figure 9.

Cabinet/Wall Sleeve Extension Installation
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. Do not permit caulking to block the
weep holes. 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 9. Outdoor drain kits must
be installed to the wall sleeve extension.
5. Continue wall sleeve installation according to
instructions on page 10-11.
