GENERAL SAFETY INFORMATION

When using electrical appliances, basic precautions should

always be followed to reduce the risk of fire, electric shock and

injury to person, including the following:

WARNING:

OF FIRE, ELECTRIC SHOCK AND INJURY TO
PERSON, OBSERVE THE FOLLOWING:

a) Use this unit only in the manner intended by the manufacturer. If you have

questions, contact the manufacturer.

b) Before servicing or cleaning the unit, switch power off at service

panel and lock the service disconnecting means to prevent power
from being switched on accidentally. When the service disconnecting
means cannot be locked, securely fasten a prominent warning
device, such as a tag, to the service panel.

WARNING: TO REDUCE THE RISK

OF FIRE, ELECTRIC SHOCK AND INJURY TO
PERSON, OBSERVE THE FOLLOWING:

a) Installation work and electrical wiring must be done by qualified

person(s) in accordance with all applicable codes and standards,
including fire-related construction.

b) Sufficient air is needed for proper combustion and exhausting of

gases through the flue (chimney) of fuel burning equipment to prevent
back drafting. Follow the heating equipment manufacturer’s guideline
and safety standards such as those published by the National Fire
Protection Association (NFPA) and the American Society for Heating,
Refrigeration, and Air Conditioning Engineers (ASHRAE), and the local
code authorities.

c) When cutting or drilling into wall or ceiling, do not damage electrical

wiring and other hidden utilities.

TO REDUCE THE RISK

by

CAUTION: FOR GENERAL VENTILATING USE ONLY.

DO NOT USE TO EXHAUST HAZARDOUS OR EXPLOSIVE
MATERIALS AND VAPORS.

d) This unit must be grounded.

e) To avoid motor bearing damage and noisy and/or unbalanced impellers,

keep drywall spray, construction dust, etc. off power unit.

f) Read all instructions before installing or using exhaust fan.

g) For residential installations only.

h) Must use suitable weather hood with insect screen to protect air

intake.

WARNING: TO REDUCE THE RISK OF FIRE,

ELECTRIC SHOCK, DO NOT USE THIS FAN WITH
ANY SOLID-STATE SPEED CONTROL DEVICE.

a) Must be connected to a GFCI (ground fault circuit interrupter)

protected branch circuit.

WARNING: DO NOT USE IN KITCHENS.

WARNING: 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 AIRFLOW.

INSTALLATION INSTRUCTIONS

CAUTION:

SERVICE PANEL BEFORE STARTING INSTALLATION.

MAKE SURE POWER IS SWITCHED OFF AT

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.

2a. Surface Mounting: Locate at least one stud or joist. Place the fan in position so that the

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).

SECTION 3

Ducting

NOTE: 6" OR LARGER RIGID DUCT IS RECOMMENDED FOR BEST PERFORMANCE.

CAUTION: ALL DUCTING MUST COMPLY WITH LOCAL AND

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: MAKE SURE THE FRESH AIR INTAKE PORT COMPLIES

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.

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: MAKE SURE POWER IS SWITCHED OFF AT

SERVICE PANEL BEFORE STARTING INSTALLATION.

CAUTION: ALL ELECTRICAL CONNECTIONS MUST BE

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 5).
