GENERAL INSTRUCTIONS
MOTORS
Periodic checks of voltage, frequency and current of a motor while in operation are
recommended. Such checks assure the correctness of frequency and voltage applied to
the motor and yield an indication of the fan load. Comparison of this data with previous
data will give an indication of the fan performance. Any serious deviations could indicate a
potential motor failure.
All motors carry a one-year warranty from date of shipment. For repairs within warranty
period, the motor must be taken to the motor manufacturer’s authorized service dealer.
Contact your representative for additional warranty details.
A periodic motor check should consist of spinning the motor shaft with the power off so to
be sure the motor turns freely and the bearings run smoothly.
Repair or replacement of motors is normally performed by a repair station authorized by
the manufacturer. Contact your representative or the factory for locations nearest you. DO
NOT ship motor to factory without specific authorization forms.
