4. Peel off protective backing
from track seal. Apply
seal to room side of window track. Center of seal strip
should coincide with the line marked in Step 2. The
two screw holes drilled in Step 3 should be directly
above seal strip in the inner track.
5. Securely attach a siding-protection board
to
side of house.
NOTE:
Siding-protection board should be long
enough to span 2 wall studs.
6. Place platform assembly,
with platform tab
against inside of window track, and attach it to
window jamb. Use appropriate length screws (Items
9-11 in Preparing For Installation).
7. Adjust platform assembly
so that outside edge is
3/16-inch lower than inside edge, as shown right.
This ensures proper water drainage from the air
conditioner.
8. Level platform assembly from side-to-side.
Also, make sure window track is level. Use leveling
shims as necessary to ensure unit is level from side-
to-side.
9. Measure height of window opening
from top of
platform assembly as shown right. Subtract 20-5/8
inches. Mark this measurement on plastic window
panel, along the longer side. (continued)
