5. Complete the electrical work in the subbase and the
junction box.
6. Rough-in the condensate drain (if used) to the left front
side of the subbase. A connection may be made between
this field supplied drain and the condensate drain which
will be installed later at the underside of the wall sleeve.
7. The subbase cavity should be fitted with a piece of 6"
(152mm) fiberglass batting to prevent condensation on
the wall sleeve basepan.
Subbase Installation:
1. The subbase provides a 1
3
⁄
16
" (30mm) inset on the sides of
the conditioner. Locate the subbase on the floor and align
its center line with the center line of the wall opening (see
Figure 5).
2. Determine the depth of the side extension pieces desired
and break at the proper score line. Insert the extension
pieces into the front assembly and secure with two short
screws on each side (see Figure 4).
3. Secure the assembly to the floor.
4. Insert the two leveling bolts into the subbase, one on each
end. Retain the two long screws to secure the wall sleeve
after it is installed.
Optional Louver Frame Installation
Whenever a louver frame is used, it must be installed prior to,
or at the same time as, the room cabinet/wall sleeve. It must
be level and square (see Figure 6).
1. Apply a bead of good caulking compound around the four
inner surfaces of the louver frame vertical flange (see
Figure 7).
2. Insert the sleeve of the louver frame into the wall opening
from the exterior of building and apply firm pressure so the
caulked louver frame vertical flanges are snug against the
exterior building surface.
3. Secure the louver frame to the wall through the sides and
top of the sleeve. Never secure the louver frame through
the bottom. Note: The louver frame may also be secured
from inside the room cabinet/wall sleeve by screws driven
through the sides and top of the louver frame sleeve.
Pre-Installation Conditioner Preparation
1. Remove the outer carton of the room cabinet/wall sleeve/
chassis package and inspect the conditioner for shipping
damage. Report any damage to the carrier.
2. Save the large inner cardboard liner which can be reused
to cover the installed conditioner until its ready for use. It
is scored, and can be easily folded to the proper depth for
the particular room cabinet exposure into the room.

3. Remove the front panel and filter. Refer to page 7 for
details.
4. Remove the retaining clips at the bottom rear of the
chassis which hold the chassis in place during shipment.
5. Remove the chassis by pulling evenly at the positions
indicated as “Hand Holds” only. Caution: Do not pull on
the evaporator fan housings or control box.
6. Check the nameplate data on the chassis to ensure that
the correct jobsite distribution has been made with re-
spect to the heating and cooling capacities. Corner rooms
normally require larger capacities.
