instructions and should be aware of general safety
precautions. Improper installation can result in electric
shock, possible injury due to coming in contact with
moving parts, as well as other potential hazards.
Other considerations may be required if high winds
or seismic activity is present. If more information is
needed, contact a licensed professional engineer
before moving forward.
1. Follow all local electrical and safety codes, as
well as the National Electrical Code (NEC) and the
National Fire Protection Agency (NFPA), where
applicable. Follow the Canadian Electric Code

2. The rotation of the wheel is critical. It must be free
to rotate without striking or rubbing any stationary
objects.

RPM. Adjustments to fan speed significantly affects
motor load. If the fan RPM is changed, the motor
current should be checked to make sure it is not
exceeding the motor nameplate amps.
5. Do not allow the power cable to kink or come in
contact with oil, grease, hot surfaces or chemicals.
Replace cord immediately if damaged.
