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.

CAUTION: FOR GENERAL VENTILATING USE ONLY. DO NOT USE

TO EXHAUST HAZARDOUS OR EXPLOSIVE MATERIALS AND VAPORS.

d) Ducted fans must always be vented to the outdoors.
e) This unit must be grounded.
f) To avoid motor bearing damage and noisy and/or unbalanced

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

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

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

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

INSTALLATION INSTRUCTIONS
CAUTION:

BEFORE STARTING INSTALLATION.

MAKE SURE POWER IS SWITCHED OFF AT SERVICE PANEL

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)
1 - Knockout Plug
1 - Instruction/Safety Sheet

2. Remove the fan’s venturi assembly, which is secured in place with one screw
through the venturi (Figure 1). This is a captive screw and will stay installed in the
venturi. Keep the venturi assembly and the grill in the carton until needed so they
do not get damaged or lost.

Figure 1

Figure 4

SECTION 4

Ducting

CAUTION: ALL DUCTING MUST COMPLY WITH LOCAL AND NATIONAL

BUILDING CODES.

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.

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.

4. Select the most convenient electrical knockout
hole and insert the knockout plug into the 2nd
knockout hole (Figure 2).

Figure 2

SECTION 2

New Construction

1. Using the gauge on the fan’s housing (Figure 3), line up housing so that it will be flush
with the finished ceiling or wall. Position the fan so that the tabs rest flat against the
joist or stud and secure with four nails (not provided) to ensure proper installation.

Figure 5

NOTE: If damper detaches from unit, reattach by snapping the collar back onto the unit.
It is designed to only fit one way.

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.

1. Run wiring from an approved wall switch carrying the appropriate rating. One
neutral (white), one ground (green or bare copper), and one hot (black lead
connected to the switch). 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.

2. 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’s receptacle. Connect the Black
wire from the wall switch to the Black wire from the fan’s receptacle. Connect the
ground wire from the house to the Green wire from the fan’s receptacle (Figure 6).
Use approved methods for all connections.

SECTION 3

Existing Construction

1. Position housing against the joist or stud and trace an outline of the housing onto
the ceiling/wall material (Figure 4). Set housing aside and cut opening, being
careful not to cut or damage any electrical or other hidden utilities. Place housing
next to the joist or stud and insure that it is flush with the finished ceiling. Secure
with four nails (not provided) to ensure proper installation (Figure 3).

Completing the Installation

SECTION 7

Use and Care

1. Reinstall the fan’s venturi by holding it at approximately a 45 degree angle, hook
the two tabs on the venturi into the slots on the housing and secure in place by
tightening the venturi screw. Rotate the blower wheel by hand to ensure it spins
freely. Now plug the fan motor into the receptacle (Figure 7).

2. Install the grill by squeezing the two ends of the springs together and installing
them up into the slots of the fan’s venturi. Push the grill up into position (Figure 8).

CAUTION: MAKE SURE POWER IS SWITCHED OFF AT SERVICE PANEL

BEFORE STARTING INSTALLATION.

1. Cleaning the Grill: Remove grill and use a mild detergent, such as dishwashing
liquid, and dry with a soft cloth. NEVER USE ANY ABRASIVE PADS OR SCOURING
POWDERS. Completely dry grill before reinstalling. Refer to instructions in Section
6 Finishing the Installation, to reinstall grill.

2. Cleaning the Fan Assembly: Unplug the motor cord from receptacle and loosen
the venturi screw to remove the venturi from the unit. Wipe all parts with a dry
cloth or gently vacuum the fan. NEVER IMMERSE ELECTRICAL PARTS IN WATER.
Refer to instructions in Section 6 Finishing the Installation,, to reinstall venturi.
