C.4 Window Installation (Continued)
STEP 4. Check the window sill and frame to be sure they are in good
condition and functioning.
STEP 5. CABINET MOUNTING – Raise the lower window
1
/4″ more than the
height of the cabinet. Carefully slide the cabinet through the opening
until the lower sill plate channel rests behind the window sill and the top
angle rests against the window (see Figure C.4.5). Center the cabinet
within the opening. Drill three (3)
5
/32″ diameter pilot holes into window
sill using the holes in the cabinet sill plate as a guide. Install three (3)
#12 x 2″ long screws (Item 4) (see Figure C.4.5).
STEP 6. OUTSIDE SUPPORT MOUNTING – Refer to Figures C.4.6 and
C.4.7 Assemble the support brackets (Item 1) to the bottom
of the cabinet with four (4) 10-24 1″ long screws (Item 2) and
four 10-24 flat nuts (Item 3). Adjust the support brackets, using
a combination of the elongated holes of the bracket and different
hole locations in the cabinet, to bring the bottom support bracket
pads in contact with the wall. A 1″ x 4″ or 2″ x 4″ SPACER SHOULD
BE USED BETWEEN THE WALL AND SUPPORT THE BRACKETS
WHEN INSTALLED ON ALUMINUM OR VINYL SIDING. Drill
5
/32″
diameter pilot holes and secure the brackets to the wall with two
(2) 12A x 2″ long screws (Item 4).
NOTE: DO NOT LEVEL the cabinet from front-to-back. Make sure there
is approximately a
3
/8″ to
1
/2″ slope (
1
/8 to
1
/4 bubble on level)
toward the outside of the house.
Adjust the support brackets to provide an inside-to-outside slope for excess
condensation drainage (refer to Standard Window Installation, Figures C.4.6
through C.4.8). Tighten all screws.
Figure C.4.3
Alternate support method A: If you have a deep window sill which prevents you
from mounting the brackets as shown in Figure C.4.8, try the following: Using the
elongated holes and different hole locations in the cabinet, set the placement of
the bracket to support the unit’s weight (Figure C.4.9). Tighten all screws.
Alternate support method B: If the window ledge gap is narrow, try the following.
Bend the bracket end tab at. Cut the bracket in two (2) places as shown in
Figure C.4.10. Bend the short piece so it will be vertical when installed. Adjust the
placement as required. Tighten all screws.
STEP 8. Measure and cut the wingboard panels (t with about
1
/8″ clearance)
from the supplied Masonite (Item 8) to t the space between the
window side channels and cabinet (Figure C.4.11). Make sure you
include the depth of the window channel.
NOTE: A good method to cut the wingboard panel is to score both sides with a
utility knife and then snap it.
NOTICE
For YOUR security and safety, YOU must
provide a means of preventing the upper
part of the window from opening.

STEP 9. To assemble the wingboard panels, push on the “J” type speed nuts
(Item 9) and spring steel clips (Item 10) (see Figure C.4.12). Secure
each panel with two (2) screws (Item 11). (see Figure C.4.13)
NOTE: THe spring steel clips will engage with the runners of the window jam.
