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. 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.

TCBRU Roof Upblast
Level 1 & 2
Always disconnect, lock and tag power source before
installing or servicing. Failure to disconnect power
source can result in fire, shock or serious injury.
When servicing the fan, motor may be hot enough
to cause pain or injury. Allow motor to cool before
servicing.
Precaution should be taken in explosive atmospheres.
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.
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.
Faire preuve de précaution dans les atmosphères
explosives.
