INSTALLATION INSTRUCTIONS
CAUTION:
SERVICE PANEL BEFORE STARTING INSTALLATION.
SECTION 1
Preparing the Fan
1. Unpack fan from the carton and confirm that all pieces are present. In addition to the
fan you should have:
2 - Collar Assembly (attached)
2 - Mounting Brackets (attached)
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. The fan mounts using the provided mounting brackets or can be surface
mounted to a wall or ceiling.
NOTE: The fan must be installed into a location that can be easily accessed once installed.
3. No additional vibration deadening materials are needed for this fan.
SECTION 2
Mounting the Fan
1. Confirm the fan is positioned so the air flow is in the correct direction.
Surface Mounting: Locate at least one stud or joist. Place the fan in position so that the
2a.
mounting bracket is centered on the stud or joist and make the location for the four (4)
holes. Remove the fan and install properly rated wall/ceiling anchors for the holes that
do not go directly into a joist or stud. Position fan in place and secure with screws (not
included) (Figure 1).

2b. Mounting to a Joist: Install two - 2 x 4 headers (not included) between the joists.
Position the fan housing on top of the headers and secure the mounting brackets with
screws (not included) to the header (Figure 2).

SECTION 3
Ducting
NOTE: 6" OR LARGER RIGID DUCT IS RECOMMENDED FOR BEST PERFORMANCE.
CAUTION:
NATIONAL BUILDING CODES.
NOTE: The ducting from this fan to the outside of the building has a strong effect on the air
flow, noise and energy use of the fan. Use the shortest, straightest duct routing possible
for best performance, and avoid installing the fan with smaller ducts than recommended.
Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed
with existing ducts may not achieve their rated air flow.
WARNING:
WITH ALL LOCAL AND NATIONAL CODES AND IS LOCATED AT LEAST 6 FEET
AWAY FROM SOURCES OF CONTAMINATION SUCH AS BUT NOT LIMITED TO: DRYER,
FURNACE OR CENTRAL VACUUM EXHAUSTS, GAS APPLIANCES SUCH AS BBQ GRILLS,
GARBAGE BINS OR OTHER EXHAUST PORTS.
NOTE: To ensure quiet operation of in-line and remote fans, each fan shall be installed using
sound attenuation techniques appropriate for the installation. For bathroom and general
ventilation applications, at least 8 feet of insulated flexible duct shall be installed between the
exhaust or supply grille(s) and the fan.
1. Connect the ducting to the fan's duct collar (Figure 4). Seal ducting to housing with
appropriately rated tape. Use screws or suitable clamps to secure in place. Make sure
the fresh air intake is connected to a properly installed intake port that is a suitable
weather hood with insect screen to protect air intake. It is recommended that low
restriction termination fittings be used.
Figure 4
2. Ensure duct joints and exterior penetrations are sealed with caulk or other similar material
to create an air-tight path to minimize building heat loss or gain and to reduce the potential
for condensation. Place/wrap insulation around duct and/or fan in order to minimize
possible condensation buildup within the duct, as well as building heat loss or gain.
NOTE: At the base of the duct adapter, there is a small diameter test port hole covered with
a plastic cap. Make sure the test port is not covered up with the ducting so that it can be
accessed for pitot tube testing. To access the port, remove the port cover and insert tube.
SECTION 4
Wiring
CAUTION:
SERVICE PANEL BEFORE STARTING INSTALLATION.
CAUTION:
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.
Remove the wire compartment cover screw and place cover in a secure place (Figure 5).
