ELECTRICAL CONNECTION

Do not connect power supply until fan is completely installed. Make
sure electrical service to the fan is locked in "off" position.
1. All units are suitable for use with solid-state speed control.
2. This unit has rotating parts and safety precautions should be exercised
during installation, operation and maintenance.
3. CAUTION: "For General Ventilation Use Only. Do Not Use To Exhaust
Hazardous Or Explosive Materials and Vapors."
4. WARNING: To reduce the risk of fire, electric shock, or injury to per-
sons-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, switch power off at the service panel and
lock service panel to prevent fan from being switched on accidentally.
c. Installation work and electrical wiring must be done by qualified per-
son(s) in accordance with all applicable codes and standards,
including fire-rated construction.
d. Sufficient air flow is needed for proper combustion and exhausting
of gases through the flue (chimney) of fuel burning equipment to
prevent backdrafting. Follow the heating equipment manufacturer's
guidelines and safety standards such as those published by the
National Fire Protection Association (NFPA), the American Society of
Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE)
and the local code authorities.
e. When cutting or drilling into a wall or ceiling, do not damage electri-
cal wires or other hidden utilities.
f. Ducted fans must always be vented to the outdoors.
g. Install fan at least five feet above the floor.
h. This product is acceptable for use over a bathtub or shower when
installed in a GFCI protected branch circuit.
i. NEVER place a switch where it can be reached from a tub or shower.
5. WARNING! Check voltage at the fan to see if it corresponds to the
motor nameplate.
Guards must be installed when this fan is within reach of personnel
or within seven (7) feet of working level or when deemed advisable
for safety.

WIRING INSTRUCTIONS

STEP 1.
Remove the screws securing the terminal box cover plate located on the
fan motor mounting bracket. All fan motor and capacitor connections are
pre-wired to an electrical terminal strip. A 3/8" romex type cable restraint
connector will be needed to secure the wiring through the knockout pro-
vided on the side of the terminal box.
STEP 2.
Bring incoming electrical service through the romex connector and the fan
electrical service opening (Refer to 1" opening. Dimensions "G" & "H"). Be
sure to place the connector nut over the wiring coming into the terminal box.
Move the capacitor to allow access to the terminal strip (see I-4). There are
two open ports on the terminal strip. Using a small regular screwdriver,
tighten the neutral (white) wire of the incoming supply under the open ter-
minal strip port labelled "N". Tighten the line (black) wire of the incoming
supply under the open terminal strip port labeled "L". Connect the neutral
wire to the ground connection on the terminal block.
STEP 3.
Secure the romex connector. Secure the incoming supply with the romex
connector. Place the capacitor back into the terminal box. Replace the fan
terminal box cover.
All fan motor and capacitor connections have been pre-wired from the
factory. No additional fan wiring is necessary.

TROUBLESHOOTING

If fan fails to operate, please check the following:
1. Consult wiring diagrams (page four of these instructions) to insure
proper connection.
2. Check motor lead wiring, capacitor leads and incoming supply leads to
insure definite contact.
3. If possible, use a meter to test for continuity across the fan motor
leads. In order to do this, the capacitor must be disconnected (do not
test the capacitor-it will not meter continuity). If motor leads show
continuity, consult manufacturer for a replacement capacitor.

MAINTENANCE INSTRUCTIONS

1. Since fan bearings are sealed and provided with an internal lubricating
material, no additional lubrication is necessary.
2. When using in a dryer boosting application, DISCONNECT POWER
SUPPLY and check impeller periodically for lint buildup.
No other maintenance is necessary.
