personal. In order to properly operate and maintain the pump and its
components, an instruction book should be consulted.
Before starting the pump, the following inspections should be made:

All wiring to the motor and starting device should match the
wiring diagram. The motor should move in a clockwise
rotation when looking at it from the back. If the motor has
been in storage for any length of time, whether used or new,
then consult the motor instructions before starting. Use the
motor data plate to check the voltage, phase, and line circuit
frequency.

In order to make sure it rotates freely, use your hands to turn
the rotating element..

All piping should be checked for leaks. Also all flange bolts
should be checked to make sure they are tightened securely..
