PREPARE
WINDOW
FOR
INSTALLATION
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 14" from the bottom of the sash to the window stool.
2. If storm window presents interference, fasten a 2" wide wood
strip (OUTER SILL) 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 (STORM WINDOW FRAME) or wood
strip (OUTDOORS) to help condensation to drain properly to the
outside.
3. Install a second wood strip (approximately 6" long by 3/2" 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 basepan angle.
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.
