SECTION IV

MOTOR OPERATING CONDITIONS

13.0

The standard Series 560 "dia-Pump" is supplied with 1/3 HP, single phase, capacitor start, totally enclosed
fan-cooled motor as an integral part of the pump itself.

The normal temperature rise for this motor is 40°C above ambient temperature and, thus, it might appear
that the motor is operating at a higher than normal temperature. This situation is normal and should not
cause concern.

As a precaution against motor overheating, it is recommended that the pump be located where adequate
ventilation is available. It is also highly RECOMMENDED THAT A MOTOR STARTER WITH THE PROPER
OVERLOAD PROTECTION BE SUPPLIED AS AN ADDITIONAL SAFETY DEVICE.
