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).

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).
