Window Installation Instructions
Preparing the Unit for Installation
Attach the Window Platform to the Window
1. Using the adjustment bolt and the hex flange nut, secure the platform support brace to the
window platform. Choose a slot for the adjustment bolt on both the platform and the
support brace that will create a 45° angle between the two pieces.
• Place the window platform assembly in the installation window to determine if the
platform sits properly and will provide the proper slope (3/16” (~3°) lower on the
outside).
• If the platform does not provide the proper slope, then move the adjustment bolt to
a different slot in the platform and support brace and test again.
2. Measure 8 11/16” from the window jamb and lightly draw a line in pencil.
NOTE: When choosing your window, make sure power supply cord is within 6 feet of a grounded
3-prong outlet. Do not use an extension cord.
NOTE:
• These instructions are for installation in a standard slider or casement window only.
• If installing the unit into a casement window, open the window to the maximum amount to allow
for clearance of the cabinet.
• If the window cannot open more than 15 ½” for the cabinet to clear the window, the entire
window can be removed. If this is necessary, contact a professional to ensure proper
installation.
Note: If you are planning to use a siding protection board (step 5) on the outside of the house,
hold down the window platform flat while testing.

3. Center the window platform on the newly drawn line with the inner (second) tab on the
bottom of the platform pressed against the inside edge of the window track. Mark two
holes on the window track or sill using the two holes on the window platform on either side
of the platform tab. Remove the window platform and then drill two 9/64” holes in either the
window track or sill in the two marked spots.
4. Apply the adhesive window sliding track sealing strip by first removing the protective
backing and then placing it to the room side of the window track. The center of the sealing
strip should coincide with the line draw in step 2. The two screw holes drilled in step 3
should be directly above the sealing strip on the inner track.
5. Securely attach a siding-protection board to the side of the house.
6. Place the window platform with the platform tab against the inside of the window track.
Fasten the window platform (allowing for some adjustment space) to the window track or
sill using the previously drilled holes and the appropriate length screws (items 9 through
11 in Parts Supplied).
7. Confirm that, when secured, the outside edge of the window platform is 5/16” (~4°) lower
than the inside. If this is not the case, adjust the window platform until it is in the correct
position and then secure it in place by tightening the screws.
