• 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 up-
ward from liquid source.
• For installations with long suction piping, fi ll 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
specifi cations. Incorrect voltage can cause fi re, dam-
age 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 OR EXPLOSION
RESULTING IN SERIOUS PERSONAL
INJURY, PROPERTY DAMAGE OR
DEATH.
• Fill pump through opening in top of tee with clean water.
See Figure 1.
• Install pipe plug in top using Tefl on™ tape or equivalent on
male threads.
NOTICE: IF PUMP IS DRAINED OR 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 system may 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.
• Single phase motors with more than 4 wires (leads) may be
reversible designs. Insure that the motor is rotating in the cor-
rect direction. See motor nameplate for wiring instructions.
• Three phase unit rotation may be checked by removing mo-
tor 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 MAINTE-
NANCE CAN CAUSE SEVERE PERSON-
AL INJURY.
FAILURE TO RELIEVE SYSTEM PRES-
SURE AND DRAIN SYSTEM BEFORE
ATTEMPTING ANY MAINTENANCE
CAN CAUSE SERIOUS 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
Tefl on™ 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.
