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.
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.

Slide the adjustable mounting brackets into the bracket channels
on the housing.

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.
