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 and lockout electrical
power before installing or servicing
the pump.
Electrical supply MUST match
pump’s nameplate specifications. In-
correct voltage can cause fire, damage
motor and void the 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.
• 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.
• Follow motor manufacturer’s wiring diagram on the motor
nameplate or terminal cover carefully.
FAILURE TO PERMANENTLY
GROUND THE PUMP, MOTOR AND
CONTROLS BEFORE CONNECTING
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. For frame mounted units, switch power
on and off quickly to observe rotation. On close coupled
units, remove motor end plug or cover to observe rotation.
• To reverse three phase motor rotation, interchange any two
power supply leads.
Operation
DO NOT OPERATE FRAME
MOUNTED OR SAE UNITS WITHOUT
SAFETY GUARDS IN PLACE OR
SEVERE PERSONAL INJURY MAY
RESULT.
SPLASHING OR IMMERSING OPEN
DRIP PROOF MOTORS IN FLUID
CAN CAUSE FIRE, SHOCK, BURNS OR
DEATH.
OPERATION AT OR NEAR ZERO
FLOW CAN CAUSE EXTREME HEAT,
PERSONAL INJURY OR PROPERTY
DAMAGE.
NOTICE: NO NOT RUN PUMP DRY OR SEAL
DAMAGE WILL RESULT.
• After stabilizing the system at normal operating conditions,
check the piping. If necessary, adjust the pipe supports.
• On frame-mounted units, coupling alignment may have
changed due to the temperature differential between pump
and motor. Recheck alignment following procedures and
hazard warnings in “COUPLING ALIGNMENT” section
of this manual.
Maintenance
FAILURE TO DISCONNECT AND
LOCKOUT ELECTRICAL POWER
BEFORE ATTEMPTING ANY
MAINTENANCE CAN CAUSE SHOCK,
BURNS OR DEATH.
FAILURE TO RELIEVE SYSTEM
PRESSURE AND DRAIN SYSTEM
BEFORE ATTEMPTING ANY
MAINTENANCE CAN CAUSE
PROPERTY DAMAGE, PERSONAL
INJURY OR DEATH.
IF PIPING HAZARDOUS OR TOXIC
FLUIDS, SYSTEM MUST BE FLUSHED
PRIOR TO PERFORMING SERVICE.
CloSE-CoUPlED UnITS
• Bearings are located in and are part of the motor. For lubrica-
tion information, refer to motor manufacturer’s instructions.

bearing frames should be regreased every ,000 hours or
at a three month interval, whichever occurs first. Use a #
sodium or lithium based grease. Fill until grease comes out
of relief fittings, or lip seals, then wipe off excess.
• Follow motor or engine and coupling manufacturer’s
lubrication instructions.
• Recheck alignment.
