STEP 5.  Check the window sill and frame to be sure they are in 
good condition and functioning.
STEP 6.  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 58). 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 58).
STEP 7.  OUTSIDE SUPPORT MOUNTING – Refer to Figures 57 
and 58. 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 59 through 61). Tighten all screws.
Alternate support method A: If you have a deep window sill which 
prevents you from mounting the brackets as shown in Figure 61, 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 62). 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 63. 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 64). 
Make sure you include the depth of the window channel.
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 65 
on Page 35). Secure each panel with two (2) screws (Item 11). 
Refer to Figure 66 on Page 36.
