Installation Instructions
Installing Unit in a Sliding Window:
NOTE:
If you are planning to use a siding-protection board (see Step 8) on the
outside of your house, hold board in place when testing assembly in window.
NOTE:
If any sash stop protrudes more than 1″ from the side window jambs, the
8-11/16″ measurement must be increased accordingly (FIG.7). Screen and
storm window frames may also require adjustments to the measurement.
For vinyl-clad windows, you need to install the support bracket on the
window track before you install the platform. Follow the instructions below to
do that.
1. Place the support bracket on the window sill as shown (FIG.8C). Using the
holes in the support bracket as a guide, mark and drill two 1/8" diameter holes.
2. Follow Step 7 to applly the track seal on the room side of window track.
3. After applly the track seal, use two 3/8" screw (item 17) to fixing the support
bracket. Make sure the support bracket is level form side to side.
Proceed to Step 9 after you finish fixing the support bracket.
