servicing pump.
Electrical supply MUST match pump's nameplate
specifications. Incorrect voltage can cause fire,
damage motor and voids warranty.
Motors equipped with automatic thermal protec-
tors open the motor's electrical circuit when an
overload exists. This can cause the pump to start
unexpectedly and without warning.
• Use only stranded copper wire to motor and ground.
Wire size MUST limit the maximum voltage drop to
10% of the motor nameplate voltage, at the motor ter-
minals. Excessive voltage drop will affect performance
and void motor warranty. The ground wire must be at
least as large as the wires to the motor. Wires should be
color coded for ease of maintenance.
• Three phase motors require all leg protection with
properly sized magnetic starters and thermal overloads.

• Check pump rotation by observing the motor fan or
the coupling THROUGH the coupling guard. DO
NOT confuse the flow arrows, stamped on the pump
body, with the rotation arrows on the coupling and
motor adapter. Three phase motors only – If rotation is
incorrect, have a qualified electrician interchange any
two of the three power cable leads.
