SECTION IV
SHELL (CABINET) PREPARATION:
It will be necessary to relocate the sill plate of the cabinet 2" back from its shipping position, and the shell guides 4" forward, to
the forward-most hole in the shell rail. Discard the chassis retainer wire disconnected in Section II, Step 3. The junction box
mounting leg from Section VI, Step 1, and the field-installed conduit will retain the chassis in the shell.
IF THIS INSTALLATION IS FOR A SASH WINDOW – With the wide flange and pilot holes of the sill plate forward, put the
screws/nuts in the rear holes of the sill plate and third shell hole from the front (the center of three square holes). Anchor the
side angles (Item #6) by engaging the tabs at each end of the sill plate with the bottom loops of the side angle. Engage the
tabs at each end of the top angle (Item #5) with the top loops of the side angle. Install two (2) screws (Item #7) to secure the
top angle tabs and the side angle to the rear-most holes in the side of the cabinet (See Figure B, below).
IF THIS INSTALLATION IS THROUGH A WALL – Turn the sill plate end to end so that the wide flange with pilot holes will
be over the wall header (towards the rear) and two inches from the front of the cabinet. Bend the tabs into the channel of the
sill plate, put the screws/nuts in the front holes of the sill plate and into the second shell hole from the front. Use one bolt on
each side to secure the sill plate to the cabinet. (See Figure C, below.)
