Bottom Cover Installation
Slide the top
fl
ange of the bottom cover into slots
located at the bottom corners of the window frame.
IMPORTANT
When the bottom cover is used instead of a fret, a
space is required in front of the barrier screen to
allow the window to move and relieve during a
hard start. It is therefore very important to ensure
that an area of 3/4 inch (19 mm) in front of the
barrier screen is kept clear at all times.
IMPORTANT
The fret retainer brackets are designed to maintain
a space in front of the screen to allow the window
to move and relieve during a hard start. It is very
important to ensure this area in front of the barrier
screen is kept clear at all times.
