of the window into the opening, then tilt the top into position.
B. Ensure the window is resting against the interior surface of the blind stops and the sill
adapter meets the original sill.
Note: The height of the window frame can be
increased by as much as 3/8" by applying the
head expander (included) to the window
frame. If more than 3/8" height adjustment
is required, install a continuous shim at
the sill.
