 WARNING

Hazardous Voltage!

Disconnect all electric power, including remote disconnects before servicing. Follow proper

lockout/tagout procedure to ensure the power cannot be inadvertently energized. Failure to

disconnect power before servicing could result in death or serious injury.

Obtain an IOM from the motor manufacturer for the specific motor installed. The motor

manufacturer’s recommendations take precedence for all matters related to the start-up and

routine maintenance of the motor.

Motor grease fittings have been removed from factory-installed motors in compliance with UL

regulations. Motor bearings require periodic maintenance throughout their life. Many different

styles of motors come as standard selections, so please obtain the motor IOM and use the

manufacturer-recommended grease.

Fan Motor Inspection

Inspect fan motors periodically for excessive vibration or temperature.
