Two of the most common ways to
connect ductwork to the unit.
The unit will operate most quietly and efficiently when located
where the shortest possible duct run and minimum number of
elbows will be needed.
Plan to supply the unit with proper line voltage and appropriate
power cable.
1. Install mounting brackets.
Slide the adjustable mounting brackets into the bracket channels
on the housing.
Bend the tabs on the cardboard protector and insert protector
into opening in housing.
NOTE: The cardboard protector shields the inside of the housing
from drywall spray and construction dust. Do not remove it until
after construction is completed.
1/8" GAP
2. Mark mounting location.
Position unit between joists and extend mounting brackets.
IMPORTANT: Position brackets so there will be an 1/8” gap
between bottom of housing and ceiling material. Mark the top
of keyhole slot on all four mounting brackets.

3. Pound in nails.
Remove unit temporarily, and pound nails partially into joists at
all four marked locations.
4. Hang and secure housing.
Hang unit from nails. Check to make sure that there will be a 1/
8” gap between bottom of housing and ceiling material. Pound
nails tight. For wide joist centers: A #8 x 3/8 self-tapping screw
can be used to join extended brackets together and create a
rigid mount. To ensure a noise-free mount, crimp the bracket
channels tightly around mounting brackets.
6. Choose power cable direction.
Remove wiring plate. When re-attached, the wiring plate allows
the power cable to enter unit horizontally or vertically.
7. Connect wiring.
