DISCHARGE
• Install a tee at the discharge connection of the pump.
The top opening of the tee is required for initial priming.
See Figure 1.
Figure 1
Wiring and Grounding
Install, ground and wire
according to local and National
Electrical Code requirements.
Install an all leg electrical power
disconnect switch near the
pump.
Disconnect electrical power
before installing or servicing
pump.
Electrical supply MUST match pump’s
nameplate 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.

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.
• Three phase unit rotation may be checked by removing
motor end cap or plug and observing rotation of motor
shaft. To reverse rotation, reverse any two of the three
motor leads.
Operation
OPERATION WITHOUT PRIME, OR
AGAINST A CLOSED DISCHARGE
VALVE, CAN GENERATE HOT
WATER 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
TM
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.
Maintenance
FAILURE TO DISCONNECT
ELECTRICAL POWER BEFORE
ATTEMPTING ANY MAINTENANCE
CAN CAUSE SHOCK, BURNS OR
DEATH.
• No lubrication is required on pump.
For motor lubrication, refer to and
follow manufacturer’s instructions.
SEASONAL SERVICE
• To REMOVE pump from service, remove all drain plugs
and drain all piping.
• To RETURN pump to service, replace all drain plugs
using Teflon
TM
tape or equivalent.
• Reconnect suction line if removed, examine union and
repair if necessary.
• Reprime and operate pump following all instructions
and warnings in the “OPERATION” section of manual.
