Installing Unit in a Casement Window

5. Adjust the platform assembly properly.
(Fig. 5)
Adjust the platform assembly so that the rear
of the air conditioner will be 5/16 inches lower
than the front. This ensures proper water drainage
from the air conditioner.
NOTE: A projection below the base of the air
conditioner will require the rear platform to be 7/16
inches lower than the front to create the 5/16 inch
slant from front to rear.
6. Securely attach a sliding-protection board.
(Fig. 6)
Attach the board to the side of the house where
the platform assembly hit the house. The siding-protection
board should be long enough to span 2 wall studs.
7. Measure the height of the window opening.
(Fig. 7)
Measure from the top of the platform assembly.
Subtract 20 5/8 inches. Mark this measurement
on the plastic window panel, along the longer side.
8. Clamp the plastic window panel.
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.
9. Fasten the side channels to the side of the unit.
Using three screws (Item #17, Pg. 10) per channel
fasten the side channels to the side of the unit. Make
sure hook ends of channels face toward the back of unit.
10. Slide the plastic window panel into panel frame.
(Fig. 8)
Slide the plastic window panel in with the smooth side
to the outside. 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.
11. Cut side channel seal. (Fig. 9)
Cut the channel seal into 2 equal lengths. Remove the
protective backing and apply it to the rear side of the
cabinet side channels, starting just below the panel frame
assembly. Pinch off excess length so the seal is even with
the bottom of the cabinet side channel.
