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. Remove the wire compartment cover by loosening the two screws holding the
cover in place
(Figure 1).
3. 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” on center joists using the provided
mounting rails.
3. Select the most convenient electrical knockout
and remove using a straight-blade screw driver
(Figure 2).
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 3).
SECTION 3
Existing Construction
1. Set housing in position between the joist and trace an outline onto the ceiling
material
(Figure 4)
. 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 3).

SECTION 4
Ducting
CAUTION:
ALL DUCTING MUST COMPLY WITH LOCAL AND NATIONAL
BUILDING CODES.
1. Remove any tape that might be holding the damper in place during shipping and
connect the ducting to the fan’s duct collar
(Figure 5).
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.
Wiring Fan/Heat Bulb(s) Independently:
Run wiring from an approved wall switch
carrying the appropriate rating. One neutral (white), one ground (green or bare
copper), and two hot (black and blue). 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.
1b. From where you have access to inside the fan’s junction box, connect the white
wire from the house to the white wire from the fan. Connect one hot (black) wire
from the house to the black wire from the fan (this is the fan control). Connect the
second hot (blue) wire from the house to the blue wire from the fan (this is the heat
bulb control). Connect the ground wire from the house to the green wire from the
fan
(Figure 6).
Use approved methods for all connections.
NOTE:
On model AK927 connect the Hot (Blue) wire from the house to the two Blue
wires from the unit.
