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
1 - Mounting Flange
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 10
"
of
clearance in the ceiling or wall, and will mount
through drywall up to 3/4
"
thick.
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 into the mounting channel on the housing. Center the mounting
channel in the slots on the housing, then from inside the housing tighten
the mounting channel nuts so the channel is securely in place. 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 into the mounting
channel on the housing. Center the mounting channel in the slots on the housing,
then from inside the housing tighten the mounting channel nuts so the channel is
securely in place. 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).

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).
1b. Internal Wire Compartment: Using a 7/16
"
socket, remove the two hex nuts
holding the blower assembly in place. Lift up on the assembly and slide it out
of the tabs on the housing
(Figure 6).
Remove the wire compartment cover
screw (or screws) and place the cover in a secure place
(Figure 7).
