Installing the Unit in a Casement Window
NOTE: Open window to maximum amount allowed for
clearance of the cabinet. Crank handle should
be removed to allow platform to be fastened to
the jamb. If window cannot open far enough
(more than 15 1/2-inches) for cabinet to clear
the window, remove 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.
1. Attach support brace to platform. Use adjustment bolt
and hex flange nut to complete assembly. Choose
the slot and adjustment bolt hole locations that will
create a 45
°
angle between the platform and support
brace. Try assembly in window to determine if
platform will rest properly, and allow proper sloping
(3/16-inch lower on outside).

NOTE: If planning to use siding-protection on the
outside of the house, hold the board in place
when testing assembly in the window.
2. Drill a 9/64-inch diameter pilot hole in window jamb
equal distance from each side of 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 window jamb to miss this slot.
