• Installation of a foot valve at the liquid source, or a check
valve after the pump discharge, is recommended.
NOTICE: FOR INSTALLATIONS WITH LONG SUCTION
PIPING, BOTH A FOOT VALVE AND A
CHECK VALVE ARE RECOMMENDED.
• To avoid air pockets, no part of the piping should be above
the pump suction connection and piping should slope
upward from liquid source.
• For installations with long suction piping, fill the suction pipe
with water before connecting to pump.
PIPING – 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.
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
specifications. Incorrect voltage can cause fire,
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 CONNECTING
TO ELECTRICAL POWER CAN
CAUSE SHOCK, BURNS, OR DEATH.
Operation
SPLASHING OR IMMERSING OPEN
DRIP PROOF MOTORS IN WATER
CAN CAUSE FIRE, SHOCK, BURNS
OR DEATH.
OPERATION WITHOUT PRIME, OR
AGAINST A CLOSED DISCHARGE
VALVE, CAN GENERATE HOT
WATER OR STEAM CAUSING
INJURY OR PROPERTY DAMAGE.
• Fill pump through opening in top of tee with clean water.
See Figure 1.
• Install pipe plug in top using Teflon™ tape or equivalent on
male threads.
NOTICE: IF PUMP IS DRAINEDOR SHUT OFF DURING
PRIMING PERIOD, ENSURE CASING IS
REFILLED BEFORE RESTARTING PUMP.
• Start the pump motor and wait for system pressure to stabilize.
If system pressure is surging, or prolonged pressure drop is
experienced, the systemmay not be completely primed.
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.
Maintenance
FAILURE TO DISCONNECT AND
LOCKOUT ELECTRICAL POWER
BEFORE ATTEMPTING ANY MAIN-
TENANCE CAN CAUSE SEVERE
PERSONAL INJURY.
FAILURE TO RELIEVE SYSTEM
PRESSURE AND DRAIN SYSTEM
BEFORE ATTEMPTING ANY MAIN-
TENANCE CAN CAUSE PERSONAL
INJURY OR PROPERTY DAMAGE.
• 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™ 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.
