SCHEMATIC WIRING DIAGRAM
FINISH THE INSTALLATION
INSTALL THE DUCTWORK
NOTE:
The duct connector has a counter-balanced damper
flap. The flap will be “open” approx. 1” when duct connector
is attached to housing. This design permits insulation to be
in direct contact with fan/light housing per UL (Underwriters
Laboratories) standards. The slightest backdraft, however,
will close the damper flap, preventing air from entering unit
or finished space.
CONNECT THE WIRING
1. Connect 4” round
duct to damper/
duct connector
and extend duct
to outside through
a roof or wall cap.
Check damper to
make sure that it
opens freely. Tape
all duct connections to make them secure and air tight.
1. Wire unit as shown. Re-install wiring plate removed in
Step 2 under “PREPARE THE HOUSING”.
2. Run electrical cable as direct as possible to unit. Do not allow
cable to touch sides or top of unit after installation is complete.
