ASSEMBLY INSTRUCTIONS
3. ATTACH DAMPER/DUCT CONNECTOR
Snap the damper/duct connector onto the fan housing. The connector
must be flush with the top of the housing, and the damper flap should
fall closed.
Insulated flexible duct is recommended for the quietest possible installation.
If rigid duct is used, a short (1-3 feet) section of insulated flexible duct will
ensure quiet operation
4. 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.
