1. Wire unit following diagram above. Run electrical cable as
direct as possible to unit. Do not allow cable to touch sides
or top of unit after installation is complete.
ATTACH THE GRILLE
INSTALL THE DUCTWORK
FLUSH
NOTE: The duct connec-
tor 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.
1. Snap the damper/duct connector onto housing. Make sure
that tabs on the connector lock into slots in housing. Top of
damper/duct connector should be flush with top of housing.
2. 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. Slide light reflector into front of grille opening. Plug light
into WHITE receptacle. Place grille / reflector combination
over protruding screw, and fasten in place using acorn nut
provided. HAND TIGHTEN acorn nut 1/4 turn after it is
snug.
2. Install light bulb (100 watt maximum - not included). Insert
one tab on light lens into a slot in the grille / reflector combination. Squeeze other tab slightly and snap into remaining
slot.
