Inspect:
• After unpacking fan, carefully inspect for any damage that may have
occurred during transit. Check for loose, missing, or damaged parts.
• Check all bolts, screws, set-screws, etc. for looseness that may have
occurred during transit. Tighten as needed. Rotate propeller by hand to
ensure it turns freely.
• See General Safety Instructions on page 3, and Cautions and Warnings
as shown.
WARNING

3
1. Do not depend on any switch as the sole means of disconnecting
power when installing or servicing the fan.
2. Always disconnect, lock-out, and tag-out power source before installing
or servicing. Failure to disconnect power source can result in fire, shock,
or serious injury.
3. Motor will restart without warning after thermal protector trips. Do not
touch operating motor; it may be hot enough to cause injury.
4. Do not place body parts or objects in fan or motor openings while motor
is connected to the power source.
5. All electrical connections should be made by a qualified electrician.
6. These utility exhaust fans are for general purpose exhaust applications
only. Do not use these exhaust fans in an area where corrosive or
explosive materials may be found.
7. Follow all local and state/provincial electrical and safety codes in the
United States and Canada, as well as the National Electrical Code (NEC)
and the Occupational Safety and Health Act (OSHA) in the United States,
and the Canadian Electric Code (CEC) in Canada.
8. Always disconnect power source before working on or near a motor or its
connected load.
9. Protect the power cable from coming in contact with sharp objects.
10. Do not kink or create tight bends in the power cable and never allow the
cable to come in contact with oil, grease, hot surfaces, or chemicals.
11. Make certain that the power source conforms to the requirements of
your specific exhaust fan model. The fan frame and motor must be
electrically grounded to a suitable electrical ground, such as a grounded
water pipe or ground wire system.
12. To reduce the risk of injury to persons, please observe the following:
In the United States, OSHA compliant guards are required when fan is
installed within 7 feet of the floor or working level. In Canada, CSA
compliant guards are required when fan is installed below 2.5 meters
(8.2 feet) above the floor or grade level.
13. Suitable for use with specific solid-state speed controls.
GENERAL SAFETY INSTRUCTIONS

INSTALLATION INSTRUCTION
1. The unit should be securely mounted in a rigid framework.
NOTE: Allowing the fan frame to flex or move will result in excess
vibrations, which may cause possible premature motor, propeller, or
shutter failure.
2. Install any auxiliary components such as thermostats, switches, or speed
controls.
3. Connect power to the motor using an approved wiring method.
Refer to the following wiring diagram.
Fan frame and motor must be securely and adequately grounded
to a suitable electrical ground, such as a ground water pipe or
ground wiring system.
