Lower
the
window
firmly
behind

Leveling
the cabinet
is not required
in
a normal

since the proper
slope is
designed
into
the
product.
However,
be sure
you
have
approximately
a one-half
bubble
(5/8")
downward
tilt
to
the
outside
for
proper
water
drainage.
If necessary,
reposition
or shim
cabinet
to provide
the proper
tilt
or
side-to-side
leveling.
Now,
tighten
all
four
filler
board
screws.
Be sure cabinet
bottom
flange
is against
rear of window
sill for proper
seal.
Finally,
make
two
l/8"
pilot
holes
into
the window
sill, using the holes in the cabinet
as a guide
(see Figure
22).
Use two
wood
screws
to secure
the bottom
of the cabinet
to
the window
sill.
(CAUTION:
BE SURE
CABINET
DOES
NOT
FALL
OUT
OF WINDOW.)
