INSTALLATION
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.

2. Mark mounting location.
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.
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.
Use a roof cap or wall cap that has a built-in damper to reduce backdrafts.
Plan to supply the unit with proper line voltage and appropriate
power cable.
