ASSEMBLY INSTRUCTIONS
3. INSTALL ROUND DUCTWORK
Connect the round ductwork (not included) to the damper / duct
connector, and run the ductwork to a roof or wall cap (not included).
Using tape (not included), secure all the ductwork connections so
that they are air tight.
The ducting from this fan to the outside of building has a strong
effect on the air flow, noise and energy use of the fan. Use the
shortest, straightest duct routing possible for best performance, and
avoid installing the fan with smaller ducts than recommended.
Insulation around the ducts can reduce energy loss and inhibit mold
growth. Fans installed with existing ducts may not achieve their rated
air flow.
CONNECT ELECTRICAL WIRING
Run 120 V AC house wiring to the location of the fan. Use only UL- approved connectors (not included) to attach the house
wiring to the wiring plate. Refer to the wiring diagram, and connect the wires as shown.
** If the wall mounted speed controller is not used, do not wire BLU(+) and WHT(-). Cap them off individually.
INSTALL GRILLE
Install ceiling material to complete the ceiling construction.
Then, cut around the fan housing.
To attach the grille assembly to the fan housing. Pinch the grille
springs on the sides of the grille assembly, and position the grille
into the housing with the grille springs in the appropriate slots.
Push the grille assembly towards the ceiling to secure.
