C) INSTALLATION USING A MOUNTING BRACKET
1
SEARCHING FOR SPACE BETWEEN CEILING JOISTS
Use an electronic stud/joist locator to determine the exact location of the ceiling joists. Oth-
erwise, drill a small hole in the ceiling and poke a bent coat hanger through the hole to feel
where the joists are located.
N.B. If joists are less than 8 inch height, add furring strips to achieve the installation height
requirement.
2
CUT-OUT SHAPE
Note – This step is easier to complete with the help of a co-worker.
Using the mounting bracket as a template, take a pencil to trace the shape of the cut-out.
• Side C of the mounting bracket must be facing the ductwork (see step 5).
• Trace along the inner edges of the template to achieve the proper cut-out dimensions.
• Pencil-in the position of the 9 pre-drilled screw holes.

CUT ALONG CUT-OUT LINES
Cut inside the lines which were traced.

CLEANING OF THE INSTALLATION ZONE
Before installing the mounting bracket, prepare the surface by dusting off any excess debris
from the ceiling opening.
