Repeat steps D and E to install the second
F
support on the other side of the case.
Adjust the leveling bolts against the sill so that
G
the supports had a slight tilt to the outside. Use
a level; about 1/2 bubble will be the correct
slant to the outside. After leveling is done,
tighten the leveling bolt nut.
NOTE: Use a steel washer between the leveling
bolts and the sill if the sill is weak.
Extend the left and right accordion panels to
H
the vertical window sashes. Drill 1/8" pilot
holes and attach the top corners with 2 Type B
screws. Use an accordion panel clamp on each
lower corner to trap the panels. Drill 1/8" pilot
holes and attach the panel clamps with 2 Type
B screws.
NOTE: Seal any openings around the case or
accordion panels with sealer or foam gaskets.
