General Safety Information
Only qualified personnel should install this fan. Personnel
should have a clear understanding of these 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 are present.
If more information is needed, contact a licensed
professional engineer before moving forward.
DANGER
Always disconnect power before working on or near
a fan. Lock and tag the disconnect switch or breaker
to prevent accidental power up.

1. Follow all local electrical and safety codes, as well
as the National Electrical Code (NEC), the National
Fire Protection Agency (NFPA), where applicable.
Follow the Canadian Electric Code (CEC) in
Canada.
2. The rotation of the wheel is critical. It must be free
to rotate without striking or rubbing any stationary
objects.
3. Motor must be securely and adequately grounded.
4. Do not spin fan wheel faster than max cataloged
fan rpm. Adjustments to fan speed significantly
effects 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.
6. Verify that the power source is compatible with the
equipment.
7. Never open access doors to a duct while the fan is
running.
