General Safety Information

Only qualiﬁed personnel should install this fan system.
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.

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 Electrical 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 maximum

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.

DANGER

Always disconnect power before working on or near a
fan. Lock and tag the disconnect switch or breaker to
prevent accidental power up.

CAUTION

When servicing the fan, motor may be hot enough
to cause pain or injury. Allow motor to cool before
servicing.

CAUTION

Precaution should be taken in explosive atmospheres.
