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(not
included) (OUTERSILL) 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 (STO RM WINDO W FRAME) or wood strip
(O UTDO O RS) 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. Thiswill raise basepan angle .
4. If the distance between STO RM WINDO W FRAME and WO O D STRIP
MOUNTED ON TOPOF INNERSILLismore than 1 , two of wood
strip are not necessary.
