General Safety Information
Only qualified personnel should install this 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.
DANGER
Always disconnect power before working on or near
this equipment. Lock and tag the disconnect switch or
breaker to prevent accidental power up.
CAUTION
When servicing the unit, the internal components may
be hot enough to cause pain or injury. Allow time for
cooling before servicing.
CAUTION
Precaution should be taken in explosive atmospheres.

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. All moving parts must be free to rotate without
striking or rubbing any stationary objects.
3. Unit must be securely and adequately grounded.
4. Do not spin fan wheel faster than maximum cataloged
fan 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.
6. Verify that the power source is compatible with
the equipment.
7. Never open access doors to the unit while it
is running.
