® If you are planning to use a siding-protection
board (see Step 29) on the outside of your house, hold the board in
place when testing the assembly in the window.
_
Drill a 9/64" diameter
pilot hole in the window jamb an equal distance from each side of the jamb (FIG.22),
and 3/16" 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.
_Peel
off the protective
backing from the track seal, and stick the seal to the window sill on the outside of the
bottom jamb as shown (FIG.23).
_
Screw the platform
assembly
to the window jamb through the pilot hole you drilled in Step 25. Use a #8 x 314"
self-threading screw (FIG.24).

Adjust the platform assembly
so that the rear of the air conditioner will be 3/16" lower than the front (tilted about
2 ° to 4 ° downward to the outside). After proper installation, condensate should not drain from the overflow drain hole
during normal use, correct the slope otherwise.
• A projection below the base of the air conditioner will require the rear of the platform to be 7/16" lower than the
front to create the 3/16" slant from front to rear (FIG.25).
_
Securely attach a siding-protection
board to the side of the house where the platform assembly hit the house
as shown (FIG.26). The siding-protection
board should be long enough to span 2 wall studs.

7/16" lower than

_
Measure the height of the window opening from the top of the platform
assembly as shown (FIG.27). Subtract 20-5/8". Mark this measurement on the
plastic window panel, along the longer side.
_
Clamp the plastic window panel between a board and a work table, and
cut along the cutting line with a fine tooth saw. Remove any burrs with a file.
_
Fasten the side channels
to the sides of the unit using three screws
(Item 17) per channel. Make sure hook ends of channels face toward the back
of unit.
_
Slide the plastic window panel into the panel frame with the smooth
side to the room. Slide the panel frame assembly into the side channels of
the air conditioner cabinet. Make sure the plastic window panel is firmly
enclosed on all sides by the retainer grooves (FIG.28).
