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: TO REDUCE THE RISK 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.

d) Ducted fans must always be vented to the outdoors.

e) If this unit is to be installed over a tub or shower, it must be marked

as appropriate for the application and be connected to a GFCI (Ground
Fault Circuit Interrupter) - protected branch circuit.

f) This unit must be grounded.

g) To avoid motor bearing damage and noisy and/or unbalanced

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

WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, DO

NOT USE THIS FAN WITH ANY SOLID-STATE SPEED CONTROL DEVICE.

CAUTION: FOR GENERAL VENTILATING USE ONLY. DO NOT USE

TO EXHAUST HAZARDOUS OR EXPLOSIVE MATERIALS AND VAPORS.

WARNING: DO NOT USE IN KITCHENS.

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

WARNING: THE DUCTING FROM THIS FAN TO THE OUTSIDE OF

MAKE SURE POWER IS SWITCHED OFF AT SERVICE PANEL BEFORE

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 - Light Assembly
1 - Damper Assembly (attached)
4 - Mounting Rails
1 - Fluorescent Lamp
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
8" of clearance in the ceiling or wall, and will mount
through drywall up to 3/4" thick. The fan mounts
between 16" or 24" on center joists using the 4
provided mounting rails.

3. Select the most convenient electrical knockout and
remove using a straight-blade screw driver (Figure 1).

4. No additional vibration deadening materials are needed
for this fan.

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 2).

Figure 1

SECTION 4

Ducting

NOTE: 4" 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.

1. Connect the ducting to the fan’s duct collar (Figure 4). Secure in place using tape

or screw clamp. Always duct the fan to the outside through a wall or roof cap. 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 (Figure 5).

SECTION 3

Existing Construction

1. Set housing in position between the joist and trace an outline onto the ceiling material

(Figure 3). 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 2).
