This unit is designed for installation in standard double hung windows with actual opening widths of22" 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 a storm window presents interference, fasten a 2" wide wood strip to the inner window sill acrossthe full width of the sill. The wood strip should be thick enough to raise the height of the window sillso that the unit can be installed without interference by the storm window frame.See Fig. 5-2. The top of the wood strip should be approximately 3/4" higher than the storm windowframe (STORM WINDOW FRAME) or wood strip (OUTDOORS) to help condensation to drainproperly to the outside.3. Install a second wood strip (approximately 6" long by 11/2" wide and same thickness as first strip) inthe center of the outer sill flush against the back off the inner sill. This will raise the L bracket asshown in Fig. 5-2.4. The thickness of the second wood strip may not be the same as the first wood strip.The thickness of the second wood strip must be defined to keep the 3/4 inch distance between theinner sill or the top of the first wood strip and the outer sill.Window RequirementsInstallationFig. 5-1 Fig. 5-2
