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.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 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 the unit while it is running.
