INSTALLATION
2. Mount hous-
ing.
Secure hous-
ing to ceiling
structure with (4)
mounting screws.
Make sure bottom
of housing will be
flush with finished
ceiling material.

brackets.
Slide the (4)
mounting brack-
ets into the chan-
nels on each end
of the housing.
3. Attach
damper
/ duct
connector
to housing.
Snap damper /
duct connector
onto housing.
Make sure con-
nector is flush
with top of hous-
ing and damper
flap falls closed.
4. Install 6-
inch round
ductwork.
Connect 6-inch
round ductwork
to damper / duct
connector. Run
ductwork to a
roof cap or wall
cap. Tape all
ductwork con-
nections to make
them secure and air tight.
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.
