SAFETY INFORMATION

6MY12716 (07-15-22)
This manual contains important information for the safe use of
this product. Read completely and do not throw away.
Reasonable care and safe methods should be practiced. Check
local codes and requirements before installation.
UNPACKING PUMP
LIFTING HAZARD. Unassisted lifting of pump can
cause injury. Mechanical assistance required.
DO NOT lift pump by power cord.
When unpacking unit, check for damage. Claims for damage must
be made at the receiving end through the delivery carrier. Damage
cannot be processed from the factory.
RISK OF FIRE OR EXPLOSION. Do not smoke or
use sparkable electrical devices or flames in a septic (gaseous)
or possible septic sump. Do not pump flammable liquids with
this pump.
PUMPS IN STORAGE OR NOT OPERATING
Pumps with silicon/carbide seals must have impellers manually
rotated (6 revolutions) after setting non-operational for 3 months
or longer and prior to electrical start-up.
Pumps with tungsten carbide seals must have impellers
manually rotated (6 revolutions) after setting non-operational
for 3 weeks or longer and prior to electrical start-up.
SEAL FAILURE PROBES
HAZARDOUS DUTY RATED PUMPS:
All submersible pumps have two factory installed moisture
detectors (seal failure probes). They should have a resistance
of around 330K ohms for the series circuit in the seal chamber.
Under normal operating conditions, the circuit remains around
330K ohms. If the circuit shows open, the circuit is not complete
indicating a broken wire, corroded wire, or loose connection.
If the lower seal leaks and moisture enters this chamber, the
moisture will settle to the bottom of the chamber and will
complete (significantly less than 330K ohms) the circuit between
the moisture detectors.
NON-HAZARDOUS DUTY RATED PUMPS:
For all non-hazardous duty rated pumps the resistance(ohm)
readings between the seal probe wires should be open in
normal operating conditions. A lower resistance indicates water
intrusion.
This circuit must be connected to a sensing unit and signaling
device. This is supplied in a manufacturer built control panel.
Failure to install such a device negates all warranties.
HEAT SENSORS
All motors in this family have heat sensors on or embedded in the
motor winding to detect excessive heat. This prevents damage to
the motor. If sensor trips due to excessive winding temperature,
the starter in the panel interrupts power to the pump. The
sensors are set to trip at 130°C.
Failure to install such circuitry would negate FM approvals and all
warranties.
POWER CORDS
DO NOT modify the cord. When wiring to a system
control, connect the pump ground lead to the system ground.
The power cord and heat sensor seal failure cord are potted into
the cord cap. The cords must not be spliced.
Each cable has a green lead. This is the ground wire and must be
grounded properly per NEC and/or local codes. Cords should be
inspected for abnormal wear and replaced accordingly.
GENERAL INFORMATION

MY12716 (07-15-22)
GENERAL INFORMATION
OVERLOAD HEATERS
If the electrical panel is not used, starters with 3 leg overload
relay must be supplied on 3 phase pumps. Each leg is to have an
identical heater sized in accordance with the nameplate amps on
the motor housing. The amp draw on these submersible motors is
slightly higher than a corresponding horsepower surface motor,
so heaters must be sized by the nameplate rating.
INSTALLING SUMP LEVEL CONTROLS FLOAT CONTROLS
In all systems, the lower or turn-off control is to be set to
maintain a minimum level in the sump. This level shall be no
more than 3-1/4" from the top of the motor housing down to the
surface of the sewage.
The second or turn-on control is set above the lower turn-off
control. The exact distance between the two floats must be a
compromise between a frequent pumping cycle (15 starts per hour
max.) to control septicity, solids and a slower cycle for energy
economy. This distance should be determined by the engineer or
consulting engineer, depending on the conditions of
the application.
INSTALLING PUMP IN SUMP
HAZARDOUS VOLTAGE. Can shock, burn, or kill.
When installing, operating, or servicing this pump, carefully
follow the safety instructions listed herein.
RISK OF FIRE OR EXPLOSION. Do not smoke or
use open flames in or around this system. Only the FM listed
products are to be used in a hazardous location applications per
NFPA 70 National Electric Code. Do not pump flammable liquids.
Do not use non-hazardous pumps in explosive environments.
Before installing the pump in the sump, lay it on its side and rotate
impeller. Impeller may be slightly stuck due to factory test water.
The impeller should turn freely. DO NOT connect the power until
after this test.
Clean all debris from sump and connect pump to piping. A check
valve must be installed on each pump and a gate or plug valve
in each pump discharge is highly recommended. This valve
should be installed on the discharge side of the check valve so
if it becomes necessary to service the check valve, the line
pressure can be cut off. Single pump systems are sometimes
installed without a check valve where it is desirable to self-drain
the discharge line to prevent freezing. This can be done only with
short discharge lines; otherwise water will return to the sump and
cause short cycling of the pump.

8MY12716 (07-15-22)
MAKING ELECTRICAL CONNECTIONS
EECTROCUTION HAZARD: Must be
installed by a qualified professional. Disconnect all electrical
power before installation or servicing the pump.
All electrical wiring must be in accordance with local codes,
and only competent electricians should make the installations.
Complete wiring diagrams are adhered to the inside cover of the
panel. It is VERY IMPORTANT to check all wires for grounds with
an ohmmeter or Megger meter after the connections are made
as one grounded wire can cause considerable trouble.
NOTICE FM rated models are only to be used in
60hz applications.
NOTICE If equipment is not properly wired and protected as
recommended, the warranty is void.
The 230 volt 3 phase pump has a dual marked
nameplate. For ordinary location pumps, voltage may be rewired
by qualified personnel. For hazardous location pumps, voltage
may be rewired by the manufacturer or a Class I, Div I equipment
qualified electrician. Once the voltage is changed, the factory
cord tag indicating 230 volt 3 phase must be removed.
For record keeping purposes, we suggest the pump be marked
externally with the new voltage and qualified personnel that
performed the change. Pumps shipped from the factory as 460
volt 3 phase cannot be rewired to any other voltage.
TO RE-WIRE THE PUMP FROM 230V TO 460V 3 PHASE
Only a 230V pump from the factory is considered dual voltage, a
cord label clearly states the factory wound voltage.
1. Remove all six (#7) cap screws then raise the cord cap
assembly enough to slip a prying instrument on opposite
sides between the cord cap casting and the motor housing.
Take care to not damage the o-ring or the machined
surfaces of the castings. Doing so could void FM agency
certifications.
2. While prying evenly on both sides; separate the cord cap
casting from the motor housing, the assembly is airtight
and will have a vacuum effect when disassembling.
3. Once separated, the cord cap can be inverted and rotated
to the outside of the pump assembly, and a bolt can be
re-used to secure the upside down cord cap to the motor
housing for ease of rewiring.
Refer to the wiring diagram within this manual for wiring
details. Once all electrical connections are finished and secure
(a crimped electrical connector is best to prevent issues due
to vibration if required), the cord cap should be re-attached
reversing the steps above. Ensure the o-ring is in place and
perform a hi-pot test for safety once everything is complete.
HEAT SENSORS AND SEAL FAILURE CONNECTIONS
Be sure heat sensor wires are connected in series with the starter
coil. Connections are provided on the terminal strip.

RISK OF FIRE OR EXPLOSION. Do not smoke or
use open flames in or around this system. Only the FM listed
products are to be used in a hazardous location applications per
NFPA 70 National Electric Code. Do not pump flammable liquids.
Do not use non-hazardous pumps in explosive environments.
CUTTING RISK. Risk of serious cutting or
amputation exists. Always keep fingers and hands away from
cutting profiles. Disconnect all power sources prior to servicing
pump. Pump may start without warning. Use caution as liner
plate is extremely sharp.
PUMP OPERATIONS STARTING SYSTEM
1. Double check all wire connections.
2. Turn pumps to Off position on H-O-A switches.
3. Turn on breakers.
4. Connect amprobe to pump power cord and turn pump on. The
pump will show high amp draw momentarily, then as pump
approaches normal running speed, amps will drop to normal
nameplate amps.
5. When using three phase pumps (208/230/460/575), turn
the H-O-A switch to Hand position on one pump and notice
operation. If pump is noisy and vibrates, rotation is wrong.
To change rotation, interchange any two line leads to pump.
Do not interchange main incoming lines. Check rotation of
all pumps in this same manner.
6. Now set both H-O-A switches to Auto position and allow
water to rise in sump until one pump starts. Allow pump to
operate until the level drops to turn-off point.
7. Allow sump level to rise to start other pump(s). Notice run
lights in panel. Pumps should alternate on each successive
cycle of operation.
8. Turn both H-O-A switches to Off position and allow sump to
fill to the override control level(s).
9. Turn switches to Auto position, and pumps should start and
operate together until level drops to turn-off point.
10. Repeat this operation and cycle several times before
leaving the job.
11. Check voltage when pumps are operating and check
the amp draw of each pump. Check amps on each pump
conductor as sometimes a high leg will exist. For excessive
voltage on one leg, the electric utility company should be
consulted.
PUMP MAINTENANCE
As the motors are oil filled, no lubrication or other maintenance is
required.
If the heat sensor and seal failure are hooked up properly, no
attention is necessary as long as the seal failure indicator light
does not come on. To ensure continuity of the seal sensor leads
on hazardous duty rated pumps only, a test light is provided on
intrinsically safe panels as standard equipment.
Before handling these pumps and controls,always
disconnect the power first. Do not smoke, use flames or devices
that can produce electrical discharge or sparks in a septic
(gaseous) or possible septic sump.
FIELD SERVICE ON ORDINARY LOCATION PUMPS
Ordinary location submersible motors that are out of warranty
can be serviced in the field by any reliable motor service shop.
Any pump that is in warranty must be returned to the factory for
service or repaired at an authorized service center. Charges will
not be allowed if (in warranty) pump is not taken to an authorized
service center. When field service is performed on a pump,
these instructions should be carefully followed.
FIELD SERVICE ON HAZARDOUS LOCATION PUMPS
Hazardous location pumps must be returned to the factory for
electrical and motor service. Any repair not at an authorized
service center will void the Factory Mutual (FM) listing. This
will ensure the integrity of the hazardous location rating of the
pump and comply with our warranty requirements.
The cords, upper and lower seal, volute and impeller
components may be repaired or replaced by an authorized
service facility without compromising the hazardous location
rating to the pump.
For any repairs in which the oil is drained, the pump must be
re-filled with an approved oil. The motor chamber cannot be
disassembled, during repairs as this will result in loss of agency
rating.
Any time a seal is disturbed, it must be replaced.
Check the pump for proper rotation before returning to service.

ADJUST CUTTER CLEARANCE ON CHOPPING MECHANISM
CUTTING RISK. Risk of serious cutting
or amputation exists. Use caution as liner plate is extremely
sharp. Always keep fingers and hands away from cutting
profiles. Disconnect all power sources prior to servicing pump.
Pump may start without warning.
1. First install the liner plate with chopper bar (Item A) into the
volute. It may be helpful to install 3/8-16 studs into the liner
plate to line up the holes with the corresponding volute
holes. You may have to tap the plate all the way down with a
rubber hammer.
2. Remove the studs and replace with 3/8-16 bolts (Item B) in
the large counterbored holes from beneath the volute, only
thread in enough to hold screws in place.
3. Install motor with impeller mounted, tighten motor housing
bolts to volute.
4. Tighten four 3/8-16 (Item C) socket head cap screws in the
chamfered counterbored holes until liner plate is sitting flat
against impeller, ensure (Item B) is still loose which allows
the liner plate to rest against the impeller.
5. Next back off the same 3/8-16 (Item C) screws away from
liner plate 1/8 - 1/4 turn for the recommended .008-.015
clearance.
6. Tighten the opposite four 3/8-16 (Item B) screws evenly
to 25-30 Ft-lbs. Ensure all screws have proper torque
to prevent backing out. A thread locking compound is
recommended to prevent vibrational loosening over time.
7. Measure the clearance with a feeler gauge it should be
between .008 to .015.
8. Spin impeller with a hex wrench in the impeller hub or use
a wooden pry bar to spin impeller to make sure there is no
rub.
9. If you hear or feel a rub, readjust the clearance by loosening
screws (Item C) evenly and retightening (Item B) screws.

PUMP TROUBLESHOOTING
Below is a list of common problems and the probable causes.
PUMP WILL NOT START
1. No power to the motor. Check for blown fuse or open circuit
breaker.
2. Selector switch may be in the Off position.
3. Control circuit transformer fuse may be blown.
4. Overload heater on starter may be tripped. Push to reset.
PUMP WILL NOT START AND OVERLOAD HEATERS TRIP
1. Turn off power and check motor leads with Megger or
ohmmeter for possible ground.
2. Check resistance of motor windings. All 3 phases should
exhibit the same reading.
3. If no grounds exist and the motor windings check OK,
remove pump from sump and check for clogged or blocked
impeller.
PUMP OPERATES WITH SELECTOR SWITCH IN HAND POSITION
BUT WILL NOT OPERATE IN AUTO POSITION
1. This indicates trouble in the float level control or the
alternator relay.
2. Check control panel for trouble.
PUMP RUNS BUT WILL NOT SHUT OFF
1. Pump may be air locked. Turn pump off and let set for
several minutes, then restart.
2. Lower float control may be hung-up in the closed position.
Check in sump to be sure control is free.
3. Selector switch may be in the Hand position.
PUMP DOES NOT DELIVER PROPER CAPACITY
1. Discharge gate valve may be partially closed or partially
clogged.
2. Check valve may be partially clogged. Raise level up and
down to clear.
3. Pump may be running in wrong direction. Low speed pumps
can operate in reverse direction without much noise or
vibration.
4. Discharge head may be too high. Check total head with
gauge when pump is operating. Total head is discharge
gauge pressure converted to feet plus vertical height from
water level in sump to center line of pressure gauge in
discharge line. Gauge should be installed on pump side of
all valves. Multiply gauge pressure in pounds by 2.31 to get
head in feet.
5. If pump has been in service for some time and capacity falls
off, remove pump and check for wear or clogged impeller.
MOTOR STOPS AND THEN RESTARTS AFTER SHORT PERIOD
BUT OVERLOAD HEATERS IN STARTER DO NOT TRIP
1. This indicates heat sensors in the motor are tripping due
to excessive heat. Impeller may be partially clogged giving
a sustained overload but not high enough to trip overload
heater switch.
2. Motor may be operating out of liquid due to a failed level
control.
3. Pump may be operating on a short cycle due to sump being
too small or from water returning to sump due to a leaking
check valve.
TROUBLESHOOTING
IF YOU HAVE ANY QUESTIONS REGARDING THE INSTALLATION, OPERATION, MAINTENANCE OR
TROUBLESHOOTING OF THE PUMP, PLEASE CALL PENTAIR AT 855-274-8947.
