voltage
• If the three phase motor(s) rotation is backwards, reverse
any two pump power cable leads at the pump control
panel.
MOTOR OVERHEAT/OVER
CURRENT SENSING DEVICES
AUTOMATICALLY RESTART THE
MOTOR UNEXPECTEDLY AND
WITHOUT WARNING. THIS CAN
CAUSE SEVERE PERSONAL
INJURY.
• After installing the pump into the containment area, with
adequate submergence, open the discharge valve fully.
Start the unit using manual controls. If flow is appreciably
less than rated performance, pump may be air bound. To
expel trapped air, jog the unit several times, using the
manual controls.
• Have a qualified electrician take current measurements on
the single or all three phases. Record these readings in the
space provided in the “OWNER’S INFORMATION”
section of this manual for future reference.
• The unit is now ready for normal operation. Place the
controls in the automatic position.
Maintenance
FAILURE TO DISCONNECT AND
LOCKOUT ELECTRICAL POWER
BEFORE ATTEMPTING ANY
MAINTENANCE CAN CAUSE
SHOCK, BURNS OR DEATH.
UNIT MUST BE FLUSHED AND
DISINFECTED, INSIDE AND OUT,
PRIOR TO SERVICING.
Periodic Maintenance
NOTICE: ROUTINE PERIODIC INSPECTIONS ARE
REQUIRED AND SHOULD FOLLOW THE
FREQUENCY AND MAINTENANCE
SCHEDULE PROVIDED.
FREQUENCY REQUIRED MAINTENANCE
MONTHLY • Duplex Units – Check for even
operating times. Uneven operation
times indicate a defective unit, float
switch or control.
• Unimpeded float operation.
WARNING

machinery
NOTICE: FOLLOW THE SPLICE KIT
MANUFACTURER’S INSTRUCTIONS.
• Where wire splices are used, follow one of these
procedures:
• Butt join the wires using properly sized and correctly
crimped Sta-Kon™, or equivalent, connectors. Insulate
and water proof each joint using heat shrink tubing
equipped with a self contained sealer. Apply heat
evenly from a torch until adequately sealed.
OR
• Use plastic insulators and a neoprene gasket sleeve set
with properly sized and correctly crimped Sta-Kon™
connectors. Place a cap and gasket on each wire end,
center insulator body over splice, insert the sleeve into
the body as far as possible, hand tighten caps.
• In the case of multiple conductors, stagger the joints.
FAILURE TO PERMANENTLY
GROUND THE PUMP, MOTOR AND
CONTROLS BEFORE CONNECTING
TO ELECTRICAL POWER CAN
CAUSE SHOCK, BURNS OR DEATH.
Operation
• If the unit has been stored for an extended period, check
the oil level in the motor and seal chamber, to insure that
they are full, using the following procedures:
• Motor Cover – With the pump in the upright position,
remove the oil fill plug (358E), being careful that
nothing enters the motor. The oil level should be above
the top of the motor. With the correct oil fill as required.
DO NOT over fill.
• Cable Gland Assemblies – Re-torque both the power
and sensor cable glands to values given in step 10 of
“POWER CABLE REPLACEMENT”.
• Before lowering the pump(s) into the containment area,
three phase units should be jogged to insure correct
rotation. See the motor rotation arrow on the motor cover
(341). Check both pumps in a duplex operation.
NOTICE:MOTOR STARTUP TORQUE, “KICKBACK”,
WILL CAUSE THE MOTOR TO TWIST IN
THE DIRECTION OPPOSITE ROTATION.
INSURE THAT THE PUMP ASSEMBLY IS
ADEQUATELY RESTRAINED.
DO NOT PLACE HANDS IN PUMP
SUCTION WHILE CHECKING
MOTOR ROTATION. TO DO SO
WILL CAUSE SEVERE PERSONAL
INJURY.
NOTICE: DO NOT SWITCH PRIMARY POWER LEADS
COMING INTO A THREE PHASE DUPLEX
CONTROL PANEL, THIS WILL REVERSE
ROTATION OF BOTH PUMPS.
