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)
2 - Mounting Brackets
1 - Mounting Flange
4 - 10-32 Nuts
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 straight­blade screw driver (Figure 1).

Centers: Install two - 2x4 headers (not included) between the joists
(Figure 4). Install the mounting brackets through the top set of slots

on the fan housing and secure in place with the four included #10­32 nuts as shown. Position the fan housing between the headers
and secure the mounting brackets with screws or nails (not included)
to the header. Adjust the height of the housing so that it is flush
with the finished ceiling by loosening the mounting bracket nuts
and sliding the housing up or down on the bracket. Fully tighten all
four nuts to secure the housing in place (Figure 5).

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

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 housing (Figure 10).
Use approved methods for all connections.

3. Install the ceiling mounting flange to cover any gaps which exist
between the housing and the finished ceiling. Line up the slots in
the ceiling mounting flange with the screws on the inside of the
