Installing the Unit in a Casement Window
1. Attach support brace to platform as shown. Use
the adjustment bolt and hex flange nut to complete
the assembly. Choose the slot and adjustment bolt
hole locations that will create a 45 degree angle
between the platform and the support brace. Try the
assembly in the window to determine if the platform
will rest properly, and allow the proper slope (3/16-
inch lower on outside). (See Figure 2-50)
2. Drill a 9/64-inch diameter pilot hole in the window
jamb an equal distance from each side of the jamb,
and 3/16-inch up from the window sill. If the hole
coincides with the window lever slot in the jamb
bottom, an additional hole will have to be drilled
through the platform edge and the window jamb to
miss this slot.
3. Peel off the protective backing from the track seal,
and stick the seal to the window sill on the outside
of the bottom jamb. (See Figure 2-51)
4. Screw the platform assembly to the window jamb
through the pilot hole you drilled in Step 2. Use
a #8 x 3/4-inch self-threading screw.
(See Figure 2-52)
5. Adjust the platform assembly so that the rear of
the air conditioner will be 3/16-inch lower than the
front. This ensures proper water drainage from the
air conditioner. (See Figure 2-53)
Open the window the maximum amount to allow for
clearance of the cabinet. The crank handle should
be removed to allow the platform to be fastened to
the jamb. If the window cannot open far enough
(more than 15-1/2 inches) for the cabinet to clear the
window, remove the window entirely by drilling out the
rivets. Bolts can serve as the pivots in the future.
To avoid crank handle and window clearance problems,
the unit can be installed in a stationary sash section.
However, the horizontal mullion and the 2 glass panels
must be removed before installation.
NOTE
If you are planning to use a siding protection board on
the outside of house, hold board in place when testing
assembly in window.

Figure 2-53.
A projection below the base of the air conditioner will
require the rear of the platform to be 7/16-inch lower
than the front to create the 3/16-inch slant from front
to rear.
