Electrical supply MUST match pump’s name-
plate specification. Incorrect voltage can cause
fire or damage to the motor and voids warranty.
Motors without built-in protection MUST be
provided with contactors and thermal overloads
for single phase motors, or starters with heaters
for three phase motors. See motor nameplate.
• Follow motor manufacturer’s wiring diagram on the
motor nameplate or terminal cover carefully.
• Use only copper wire to motor and ground. The ground
wire MUST be at least as large as the wire to the motor.
Wires should be color coded for ease of maintenance.

FAILURE TO PERMANENTLY
GROUND THE PUMP, MOTOR AND
CONTROLS BEFORE CONNECT-
ING TO ELECTRICAL POWER CAN
CAUSE SHOCK, BURNS, OR DEATH.
Rotation
NOTICE: INCORRECT ROTATION MAY CAUSE
DAMAGE TO THE PUMP AND VOIDS THE
WARRANTY.
• Correct rotation is right hand, CLOCKWISE when
viewed from the motor end.
Operation
OPERATION WITHOUT PRIME, OR
AGAINST A CLOSED DISCHARGE
VALVE, CAN GENERATE HOT WA-
TER OR STEAM CAUSING INJURY
OR PROPERTY DAMAGE.
NOTICE: DO NOT OPERATE PUMP
WITHOUT PRIME OR SEAL
DAMAGE WILL RESULT.
• Prime pump by filling pump and piping through
opening in top of tee with clean water. See Figure 1.
• Install pipe plug in top of tee using Teflon™ tape or
equivalent.
NOTICE: IF PUMP IS DRAINED OR SHUT OFF
DURING PRIMING PERIOD, CASING
MUST BE REFILLED BEFORE
RESTARTING PUMP.
• Start the pump and partially open discharge valve and
wait for system pressure to stabilize. If system pressure is
surging, or prolonged pressure drop is experienced, the
system may not be completely primed.
