5. Connect Electrical Wiring
Run 120V 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 below, and connect the wires
as shown.
5. ASSEMBLY INSTRUCTIONS
1.
Mount Housing to Joist of I-Joist
Hold the housing so that it is in contact with the
bottom of the joist. Place the fan housing next
to the ceiling joist. Using wood screws, attach
the housing loosely to the ceiling joist through
the keyholes in the mounting tabs. Adjust the
housing to be flush with the finished ceiling. For
the grille to fit properly, the housing’s rim must
not extend beyond the finished ceiling surface.
When the housing is correctly adjusted, tighten
the screws in the slots.
2.
Mount With Hanger Bars
Insert the hanger bars into the slots in the
housing. Place the fan housing between the
joists, make sure the bottom of the housing is
even with the finished ceiling. Extend the hanger
bars to the joist. Use screws to secure the
hanger bars to the ceiling joists. Select a proper
hole and secure the hanger bars together using
flange screws.
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.
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. 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.
The ducting from this fan to the outside of the 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.
