General Safety Information
(Continued)
ground wire connected to the bare metal of
the motor frame, or other suitable means.
Motor will restart
without warning after
protector trips.
3. Always disconnect power source and lock it
in the open position before working on or
near a motor or its connected load.
In United States
to reduce the risk of injury
to persons, OSHA complying guards are required
when fan is installed within 8 feet of floor, ground, or
working level.
In Canada to reduce
the risk of injury to
persons, CSA complying guards are required when fan
is installed below 2.5 meters (8.2 feet) above floor or
grade level.
Do not use in
explosive atmospheres.
4. Be careful when touching the exterior of an
operating motor; it may be hot enough to be
painful or cause injury. With modern motors
this condition is normal if operated at rated
load and voltage; modern motors are built to
operate at higher temperatures.
5. Protect the power cable from coming in
contact with sharp objects.
6. Do not kink power cable and never allow the
cable to come in contact with oil, grease,
hot surfaces, or chemicals.
7. Make certain that the power source
conforms to the requirements of your
equipment.
Installation
1. Frame in the wall opening with 2 x 4”
lumber, to form a square. The opening
should be 1/2” larger than the shutter frame
(See Figure 1, dimension C).
2. Insert the fan (shutter end first) through the
opening. Attach the flange to the frame
using nails or screws (Not furnished).
3. Connect power supply to the motor using an
approved wiring method. See preferred
wiring diagram in Figure 2.
The fan motor must
be securely and adequately
grounded to a suitable electrical ground such as a
grounded water pipe or ground wire system!
4. Before activating the fan, double-check to
ensure that there are no obstructions
(framing, stud, shutter, etc.) which would
interfere with proper fan operation.
Operation
1. Keep the area free of objects that could
impede air flow on either the intake side or
exhaust side of fan.
2. For proper exhausting, a window, door, or
louver should be opened on the opposite side
of the area to be ventilated.
3. Turn the fan ON, the shutter will open
automatically. When the unit is turned OFF,
the shutter will close.
Maintenance
Do not depend on
any switch as sole means of
disconnecting power when installing or servicing the fan.
If the power disconnect is out-of-sight, lock it in the
open position and tag to prevent application of power.
Failure to do so may result in fatal electrical shock.
l’installation ou
d’une réparation du
ventilateur, ne pas compter sur un sélecteur comme
seul moyen de coupure de l’alimentation électrique.
Si l’interrupteur d’alimentation est hors de vue, le
verrouiller en position d’arrêt et apposer une
plaquette interdisant son utilisation. À défaut, un
choc électrique pourrait être fatal.
Minor and Routine
1. Disconnect and lock out power source
before servicing.
2. Lubricate the motor sleeve bearings every six
months using S.A.E. 20 non-detergent oil.
Refer to Figure 2 for location of oil ports.
3. Ball bearing motors are permanently
lubricated at the factory. No further
lubrication is necessary.
4. Periodically clean the propellers, guard,
motor, and shutter of any accumulated dirt.
Parts Replacement
1. Refer to Figure 3 for parts placement.
2. Disconnect power before servicing.
3. Remove the four screws holding the guard
to the venturi panel. Remove the
guard/motor/propeller assembly.
4. Loosen the setscrew on blade hub and
remove the propeller.
Do not repair
damaged propellers. They
should be replaced with a properly balanced
replacement.
Maintenance
6. Loosen the nuts holding motor on guard and
remove motor. On split phase models, it is
also necessary to loosen and remove bolt and
nut holding wire brace to motor yoke tabs.
6. Reassemble the unit in reverse order of
disassembly.
Propeller is
installed hub first on motor
shaft, flush with end, and setscrew located over the
flat area.
