How to Install
Window Requirements
All supporting parts should be secured to
firm wood, masonry, or metal.
1. This unit is designed for installation in standard double
hung windows with actual opening widths of 22" to 36".
The upper and lower sash must open sufficiently to allow
a clear vertical opening of 13" from the bottom of the
sash to the window stool.
2. If storm window presents interference, fasten a 2" wide
wood strip to the inner window sill across the full width of
the sill. The wood strip should be thick enough to raise
the height of the window sill so that the unit can be
installed without interference by the storm window
frame. See Figure. 4. Top of wood strip should be
approximately 3/4" higher than the storm window frame
(STORM WINDOW FRAME) or wood strip (OUT-
DOORS) to help condensation to drain properly to the
outside.
3. Install a second wood strip (approximately 6" long by 11/2"
wide and same thickness as first strip) in the center of the
outer sill flush against the back off the inner sill. This will
raise the L bracket as shown Figure. 4.
4. If the distance between STORM WINDOW FRAME and
WOOD STRIP MOUNTED ON TOP OF INNER SILL is
more than 1", two of wood strip are not necessary.
