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
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 side 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 side 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).

1b. Internal Wire Compartment: Remove the screw holding the venturi
in place. Lift the venturi up and at an angle to slide it out of the
housing (Figure 6). Remove the wire compartment cover screw
and place the cover in a secure place (Figure 7).
NOTE: If the fan motor plug is
connected to the fan housing
receptacle, unplug so the
venturi can be completely
removed.
2. Run wiring from an approved wall switch carrying the appropriate
rating. One neutral (white), one ground (green or bare copper), and
one hot (black lead connected to the switch). Secure the electrical
wires to the housing with an approved electrical connector. Make
sure you leave enough wiring in the box to make the connection
to the fan’s receptacle.
3. From where you have chosen to access the fan’s junction box,
connect the White wire from the house to the White wire from the
fan’s receptacle. Connect the Black wire from the wall switch to
the Black wire from the fan’s receptacle. Connect the ground wire
from the house to the Green wire from the fan’s receptacle (Figure
8). Use approved methods for all connections.
NOTE: The fan’s receptacle wires might need to be pulled outside
compartment for connection. Only pull the three loose wires outside of
compartment. Additional wires will be present.
4. Carefully tuck wire back inside wire compartment and replace wire
compartment cover securing with the screw that was removed earlier.
SECTION 6
Completing the Installation
1. If the fan’s blower assembly was removed during the wiring
process, reinstall the blower by reversing the directions in
Step
1b
in Section 5 Wiring .
2. Plug the fan’s quick connect motor cord into the receptacle. This
cord will only fit one way into the receptacle (Figure 9).
3. Install the grill by squeezing the two ends of the springs together
and installing them up into the slots on the fan’s housing. Push the
grill up into position (Figure 10).
4. Restore power and test your installation.
SECTION 7
Use and Care
CAUTION: MAKE SURE POWER IS SWITCHED OFF AT SERVICE
PANEL BEFORE SERVICING THE UNIT.
1. Cleaning the Grill: Remove grill and use a mild detergent, such as
dishwashing liquid, and dry with a soft cloth. NEVER USE ANY
ABRASIVE PADS OR SCOURING POWDERS. Completely dry grill
before reinstalling. Refer to instructions in Section 6
Finishing the
Installation
