STEP 3: FOAM SEAL ON WINDOW FRAME
•
Affix the foam seal (with adhesive z) to the bottom of the window sash.
STEP 4: MOUNT THE UNIT IN THE WINDOW FRAME
1. With the help of another person, center the unit on
the windowsill. The lower rail should be completely
flush with the windowsill. Gently lower the window
until it holds the upper rail in place. The chassis is
configured to allow for a natural pitch towards the
outside of about 3-5°.
2. Extend the window fillers to the right and left edge
of the window.
