Installation Clearance Proper clearance enhances the cooling efficiency of the unit and prevents heat radiation of the condenser. 1. If a 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. 2. See Figure. B. The top of the wood strip should be approximately 3/4" higher than 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 11/2" wide and same thickness as first strip) in the center of the sill flush against the back off the inner sill. This will raise the L bracket as shown Figure. B. 4. If the distance between Storm Window Frame and Wood Strip Mounted on Top of Inner Sill is more than 1", two of wood strips are not necessary.
