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 - Duct Adapter Panel
1 - Side Panel (attached)
1 - Damper Assembly (attached)
2 - Mounting Brackets
1 - Hardware bag
7 - Screws
4 - 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,
the radius of each elbow be as large as possible for the installation, and that insulated
hard ducting be used. This fan will require at least 12" of clearance in the ceiling or wall,
and will mount through drywall up to ½" thick. The fan mounts between 24" on center
joists using the provided mounting brackets.
3.
No additional vibration deadening materials are needed for this fan.
SECTION 2
Determine Discharge
1.
Determine if you will require the unit to exhaust vertically/horizontally or at a right angle
and install the included duct adapter panel accordingly, using the included screws
(Figure 1).
NOTE:
In the right angle configuration the air will enter the unit and flow out the side at a 90°
angle. In the horizontal/vertical discharge configuration, the air will enter the unit and flow
directly out the other side.
2.
Once the duct adapter panel is installed, using the same procedure as in Step 1, install
the side panel onto the open end of the housing (this will be dependent on how you
have chosen to exhaust the unit).
SECTION 3
Mounting to a Joist
1.
If the mounting brackets are not already in place, install both brackets through the top
set of slots on the fan housing and secure in place with the four included nuts as shown.
Center the fan housing between the joists and secure the mounting brackets with screws
(not included) to the joist. Adjust the height of the housing so that it will be flush with the
finished ceiling by loosening the mounting bracket nuts and sliding the housing up or
down on the bracket. Full tighten all four nuts to secure the housing in place
(Figure 2).

SECTION 4
Hanging Installation
1.
If the mounting brackets are not already in place, install both brackets through the top
set of slots on the fan housing and secure in place with the four included nuts as shown.
Lift unit up onto the threaded rods and secure in place using appropriate hardware (not
included)
(Figure 3).
SECTION 5
Ducting
CAUTION:
ALL DUCTING MUST COMPLY WITH LOCAL AND
NATIONAL BUILDING CODES.
NOTE:
To ensure quiet operation, at least 8 feet of insulated flexible duct or insulated duct board
needs to be installed between the exhaust or supply grille(s) and the fan.
1.
Before installing the ducting, make sure the fan’s 2 pin and 3 pin quick connect motor
cords are plugged into the corresponding receptacle located on the interior wire
compartment cover. These cords will only fit one way into the receptacles
(Figure 4)
.
2.
Connect the ducting to the fan’s duct collar
(Figure 5).
Seal ducting to housing with
appropriately rated tape. Use screws (rectangular duct) or suitable clamps (round duct)
to secure in place. Do not allow screws to interfere with operation of damper. Always
duct the fan to the outside through a wall or roof cap. It is recommended that low
restriction termination fittings be used.
SECTION 6
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.
1.
Remove the wire compartment cover screw and place cover in a secure place
(Figure 6).
