Hard Foam Shims (For Some Installations)
To determine whether you need to install the hard foam shims, place the panel assembly in the bottom sash
channel and slide it until it sits tightly against the exterior side of the channel. Close the sash until it holds the
panel assembly in place. Align the vent hose with the panel opening. If the inside window frame interferes
with the proper alignment of the vent hose, follow the instructions below to install the hard foam shims.
Otherwise, continue to step 3.
Panel
Outdoor
To install hard foam shims:
extension panel B or C to minimize gaps. Then attach the hard-foam shim(s) G along the bottom side of the
window panel assembly to allow the vent hose to clear the window frame. (See image in step 3.)

Attaching Foam Weather Seals
Attach the foam weather seals D to the top and bottom sides of the panel assembly. Attach the short foam
weather seals F to the right and left sides of the panel assembly.
(Attaching the foam weather seals to the panel assembly rather than the window sash and frame makes for
easier cleanup when removing the panel assembly.)
• NOTE:
Take care not to block drain holes in the exterior sill. If necessary, cut slots in the foam seal to allow
any moisture to drain out the window sill drains.
