INSTALLATION INSTRUCTIONS

FOR "SC" MODELS

CASEMENT SASH WINDOW INSTALLATIONS.

These models will fit casement window openings as follows:

HEIGHT : 10-13/16" Minimum to 1 1-3/4" Maximum
WIDTH: 14-3/4" Minimum to 18-3/8" Maximum

STEP 1 Remove the unit from the shipping carton. Remove the tape holding the decorative front in place.

Remove the front and place it out of the way . Slide the unit out of the shell. As you slide the unit out,
you will notice a foam gasket between the chassis and the cabinet. Save the gasket for STEP 7.

STEP 2 Remove the glass, putty and window crank, if necessary . Measure the horizontal width dimension “W”

or window frame opening (Figure 1). If dimension “W” is 16" (405 mm) or less, no adjustment of the
side bracket is necessary. If the dimension is more than 16" (405 mm) – loosen the two (2) acorn nuts
and slide the side brackets out. (Add one inch (25 mm) to the measured “W” dimension for this
adjustment.) Tighten the acorn nuts. (Figure 2).

STEP 3 Remove the paper backing from the 36" (91 mm) strip of foam gasket (3/8" x 3/4"(10 mm x 19mm)) and attach

it to the back side of the top and side brackets (Figure 2). The edge of the gasket and brackets should be
flush. Press the gasket firmly in place.

STEP 4 Slide the outer shell into the window opening as far as the sill channel will permit. The back side of the sill

channel must be in contact with the front side of the window frame (Figure 3). Drill two (2) 9/64" (3.6mm)
diameter pilot holes in the lower part of the window frame.

NOTE: Use the first empty hole in the bottom side rails of the shell, just back of the steel sill channel as a

guide. Secure the shell to the window channel with two (2) hex-head self-tapping screws 1-1/8"
(29 mm) long in the pilot holes. Part # 906-022-02 (Figure 3).

STEP 5 Position the support brackets as shown in Figure 4. Attach to the shell with four (4) truss-head 10-24 machine

screws and four (4) flat nuts. Secure the bottom of the support brackets to the wall with two (2) wood screws.
Check the shell to allow for a 1/4" (6 mm) downward slope towards the outside. If used on other than wood
construction, screw the support brackets to a piece of 2" x 4" material.
