SECTION 4
Ducting
CAUTION: ALL DUCTING MUST COMPLY WITH LOCAL
AND NATIONAL BUILDING CODES.
1. Connect the ducting to the fan’s duct collar (Figure 4). Secure
in place using tape or screw clamp. Always duct the fan to
the outside through a wall or roof cap.
SECTION 5
Wiring
CAUTION: MAKE SURE POWER IS SWITCHED OFF AT
SERVICE PANEL BEFORE STARTING INSTALLATION.
CAUTION: ALL ELECTRICAL CONNECTIONS MUST BE
MADE IN ACCORDANCE WITH LOCAL CODES, ORDINANCES,
OR NATIONAL ELECTRICAL CODE. IF YOU ARE UNFAMILIAR
WITH METHODS OF INSTALLING ELECTRICAL WIRING, SECURE
THE SERVICES OF A QUALIFIED ELECTRICIAN.
NOTE: This unit includes a side access panel for wiring that does
not require the removal of the fan’s blower assembly. If you
choose to wire the unit from the inside, you will need to remove
the blower assembly and internal wiring compartment. Both
methods are equally effective.
1a. External Wire Compartment: Remove the wire compartment
cover screw and place cover in a secure place (Figure 5).
INSTALLATION INSTRUCTIONS
CAUTION:
MAKE SURE POWER IS SWITCHED OFF AT
SERVICE PANEL BEFORE STARTING INSTALLATION.
SECTION 1
Preparing the Exhaust Fan
1. Unpack fan from the carton and confirm that all pieces are
present. In addition to the exhaust fan you should have:
1 - Grill
1 - Damper Assembly (attached)
4 - Mounting Rails
2 - 13 Watt Fluorescent Bulbs
1 - Instruction/Safety Sheet
2. Choose the location for your fan. To ensure the best air and
sound performance, it is recommended that the length of
ducting and the number of elbows be kept to a minimum, and
that insulated hard ducting be used. Larger duct sizes will
reduce noise and airflow restrictions. This fan will require at
least 8" of clearance in the ceiling or wall, and will mount
through drywall up to 3/4" thick. The
fan mounts between 16" or 24" on
center joists using the 4 provided
mounting rails.
3. Select the most convenient
electrical knockout and remove
using a straight-blade screw driver
(Figure 1).
SECTION 2
New Construction
1. Install the rails on the housing and position the housing next
to the joist. Line up housing so that it will be flush with the
finished ceiling. Secure the ends of the rails with screws or
nails (not included) to the joists and slide the housing into
the final position (Figure 2).
SECTION 3
Existing Construction
1. Set housing in position between the joist and trace an outline
onto the ceiling material (Figure 3). Set housing aside and
cut opening, being careful not to cut or damage any electrical
or other hidden utilities. Install the rails on the housing and
position the housing in the previously cut hole so that it is
flush with the finished ceiling. Secure the ends of the rails
to the joists (Figure 2).
