Window Kit
These window kits are intended for indoor applications at temperatures between 55° F and 125° F. For more severe applications, Hoffman’s metal framed PWK window kits are required. See Bulletin A80.
INSTALLATION INSTRUCTIONS:
-
Using a square or a ruler for a guide, locate position desired for window installation. Any shape or size cut out is permissible, providing the opening is at least one inch less than the sheet size on all sides. For example, a 5×6 inch opening requires a sheet size of 6×7 inches; see figure 1. Drill 9/64 inch diameter holes 1/4” from edge of opening in each corner and at least every four inches around the perimeter. Note: Check gasket areas and installed equipment for possible interference.
-
Cut out window opening. File edges of cut−out as required to produce a smooth and straight edge as this cut edge will be visible.
-
When the kit is installed in painted enclosures, touch−up raw edge with proper touch−up primer and paint. See Hoffman bulletin A80 for spray paints.
-
Apply the high strength double stick tape around the inside of the cut−out. Install it very close to the edge of the window cut−out as shown in figure 1. Butt joints must be horizontal and without any gaps as shown in figure 2. For smaller openings, more tape can be applied to the outer perimeter or corners of the window material as in figure 3.
-
Carefully place the window in position using the outer edge of the tape as a location guide. When the window is properly positioned, push it firmly against the tape. The tape will change color slightly when the seal is made. Do not expect to reposition
the window once it has been stuck down. -
Using the predrilled holes in the cover of the door as pilot holes, drill through the plastic with a 9/64 inch diameter drill. Secure with the fasteners provided to a torque of 5 to 10 in−lbs.
