APWKE133 Window Kit

Product Information: Window Kit

The Window Kit is a product designed for installation in painted
enclosures to allow for visibility and access. It includes a
polycarbonate sheet, high strength double stick tape, and fasteners
for secure installation. The kit is suitable for any shape or size
cut out, as long as the opening is at least one inch less than the
sheet size on all sides.

Product Usage Instructions:

1. Using a square or ruler, determine the desired position for
   window installation. Mark the location for the cut out, ensuring it
   is at least one inch smaller than the polycarbonate sheet size on
   all sides.
2. Drill 9/64 inch diameter holes 1/4 inch from the edge of the
   opening in each corner and at least every four inches around the
   perimeter. Check gasket areas and installed equipment for possible
   interference.
3. Cut out the window opening, and file the edges as necessary to
   create a smooth and straight edge.
4. If installing in painted enclosures, touch-up the raw edge with
   the appropriate touch-up primer and paint.
5. Apply the high strength double stick tape around the inside of
   the cut-out, close to the edge. Ensure butt joints are horizontal
   and without gaps.
6. For smaller openings, additional tape can be applied to the
   outer perimeter or corners of the window material.
7. Carefully place the window in position, aligning it with the
   tape. Press it firmly against the tape to create a seal.
8. Using the predrilled holes in the cover of the door as pilot
   holes, drill through the plastic using a 9/64 inch diameter
   drill.
9. Secure the window with the provided fasteners, tightening them
   to a torque of 5 to 10 in-lbs.

Note: Once the window is stuck down, it cannot be
repositioned.

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:
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
