18. Cut the large foam seal to fit the length of the
window. Insert the foam seal between the top of
the lower window sash and the window panes of
the upper window. See Fig. 9. Make sure there is
a firm fit to prevent air leakage between the win-
dows. This also prevents insects from entering
through the window.
19. Pull out the expanding side panels from the sides
of the cabinet. The panels should expand to cover
the entire width of the window. See Fig. 10. There
is a hole provided in the ends of each wing panel
which is used to secure the panels to the window.
With the wing panels expanded, mark the drilling
locations on the sides of the window frame
(through the holes in the panels).
20. Drill the holes marked in Step 12 with

21. Lift chassis and carefully slide it into the cabinet.
Be sure that it is firmly seated towards the rear of
the cabinet.

ing chassis. Damage to unit or personal injury could
