Install, ground and wire
according to local and National
Electrical Code requirements.
Install an all leg disconnect
switch near pump.
Disconnect and lockout electri-
cal power before installing or
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.
PERMANENTLY GROUND THE
PUMP, MOTOR AND CONTROLS
PER NEC OR LOCAL CODES BE-
FORE CONNECTING TO ELECTRI-
CAL POWER. FAILURE TO DO SO
CAN CAUSE SHOCK, BURNS OR
DEATH.
• Connect the electrical leads to the motor, as follows:
• Single Phase Motors – Connect the BLACK wire to the
BLACK motor wire. Connect the WHITE wire to the
WHITE motor wire. Connect the GREEN wire to the
GREEN motor wire.
• Three Phase Motors – See Figure 3.
Figure 3
NOTICE: UNIT ROTATION IS CLOCKWISE WHEN
VIEWED FROM MOTOR END.
INCORRECT ROTATION MAY CAUSE
DAMAGE TO THE PUMP AND VOIDS
WARRANTY.
• 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.
DO NOT OPERATE UNIT WITH-
OUT SAFETY GUARD IN PLACE.
TO DO SO CAN CAUSE SEVERE
PERSONAL INJURY.
NOTICE: PUMP MUST BE COMPLETELY PRIMED
BEFORE OPERATION.
DO NOT OPERATE PUMP AT OR
NEAR ZERO FLOW. TO DO SO CAN
CAUSE EXTREME HEAT, DAMAGE
TO THE PUMP, INJURY OR PROP-
ERTY DAMAGE.
• After stabilizing the system at normal operating condi-
tions, check piping for correct alignments. If necessary,
adjust pipe supports.
MOTOR THERMAL PROTECTORS
CAN RESTART MOTOR UNEX-
PECTEDLY AND WITHOUT WARN-
ING, CAUSING SEVERE PERSONAL
INJURY.
• See the “ENGINEERING DATA” section in this
manual for the recommended maximum pump starts
per hour.
DISCONNECT AND LOCKOUT
ELECTRICAL POWER BEFORE
ATTEMPTING ANY MAINTE-
NANCE. FAILURE TO DO SO CAN
CAUSE SHOCK, BURNS OR DEATH.
• Unit motor requires regular lubrication maintenance.
