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 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
(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.
DANGER
Always disconnect, lock and tag power source
before installing or servicing. Failure to disconnect
power source can result in fire, shock or serious
injury.
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.
DANGER
Pour écarter les risques d’incendie, de choc
électrique ou de blessure grave, veiller à toujours
débrancher, verrouiller et étiqueter la source de
courant avant l’installation ou l’entretien.
ATTENTION
Lors de toute intervention sur la soufflante, le moteur
peut être suffisamment chaud pour provoquer
une douleur voire une blessure. Laisser le moteur
refroidir avant toute maintenance.
ATTENTION
Faire preuve de précaution dans les atmosphères
explosives.
