SAFETY FIRST!
PLEASE READ THIS BEFORE INSTALLING
OR OPERATING PUMP.
GENERAL
1. Most accidents can be avoided by using COMMON SENSE.
2. Read the operation and maintenance instruction manual supplied with the pump.
3. Do not wear loose clothing that may become entangled in the impeller or other moving parts.
4. Always wear appropriate safety gear, such as safety glasses, when working on the pump or piping.
5. Bronze/brass and bronze/brass fitted pumps may contain lead levels higher than considered safe for potable water
systems. Various government agencies have determined that leaded copper alloys should not be used in potable water
applications. For non-leaded copper alloy materials of construction, please contact factory.
PUMPS
6. Pumps build up heat and pressure during operation-allow time for pumps to cool before handling or servicing.
7. Only qualified personnel should install, operate and repair pump.
8. Keep clear of suction and discharge openings. DO NOT insert fingers in pump with power connected.
9. Do not pump hazardous materials (flammable, caustic, etc.) unless the pump is specifically designed and designated to
handle them.
10. Do not block or restrict discharge hose, as discharge hose may whip under pressure.
11. Make sure lifting handles are securely fastened each time before lifting.
12. Do not lift pump by the power cord (if applicable).
13. Do not exceed manufacturers recommendation for maximum performance, as this could cause the motor to overheat.
14. Secure the pump in its operating position so it can not tip over, fall or slide.
15. Keep hands and feet away from impeller when power is connected.
16. Submersible Pumps are not approved for use in swimming pools, recreational water installations, decorative fountains or
any installation where human contact with the pumped fluid is common.
17. Do not operate pump without guards and safety devices in place.
18. When towing pump behind a vehicle; make sure hitch is properly attached, always attach safety chains.
19. Always replace safety devices that have been removed during service or repair.
20. Operation against a closed discharge valve will cause premature bearing and seal failure on any pump, and on end suction
and self priming pump the heat build may cause the generation of steam with resulting dangerous pressures. It is
recommended that a high case temperature switch or pressure relief valve be installed on the pump body.
ELECTRICAL
21. To reduce risk of electrical shock, pump must be properly grounded in accordance with the National Electric Code (NEC),
or Canadian Electrical Code (CEC) and all applicable state, province and local codes and ordinances.
22. To reduce risk of electrical shock, always disconnect the pump from the power source before handling or servicing.
23. Any wiring of pumps should be performed by a qualified electrician.
24. Never operate a pump with a power cord that has frayed or brittle insulation.
25. Cable should be protected at all times to avoid punctures, cut, bruises and abrasions - inspect frequently.
26. Never handle connected power cords with wet hands.
27. Never operate a pump with a plug-in type power cord without a ground fault circuit interrupter.
28. Do not remove cord and strain relief. Do not connect conduit to pump.
29. To reduce risk of electrical shock, all wiring and junction connections should be made per the NEC or CEC and applicable
state or province and local codes. Requirements may vary depending on usage and location. See wiring diagrams in manual.

SECTION B: GENERAL INFORMATION
B-1) To the Purchaser:
Congratulations! You are the owner of one of the finest pumps
on the market today. Barnes®Pumps are products
engineered and manufactured of high quality components.
Over one hundred years of pump building experience along
with a continuing quality assurance program combine to
produce a pump which will stand up to the toughest
applications.
This Barnes Pumps, Inc. manual will provide helpful
information concerning installation, maintenance, and proper
service guidelines.
B-2) Receiving:
Upon receiving the pump, it should be inspected for damage
or shortages. If damage has occurred, file a claim immediately
with the company that delivered the pump. If the manual is
removed from the packaging, do not lose or misplace.
B-3) Storage:
Short Term- Barnes Pumps are manufactured for efficient
performance following short inoperative periods in storage.
For best results, pumps can be retained in storage, as factory
assembled, in a dry atmosphere with constant temperatures
for up to six (6) months.
Long Term- Any length of time exceeding six (6) months, but
not more than twenty-four (24) months. The units should be
stored in a temperature controlled area, a roofed over walled
enclosure that provides protection from the elements (rain,
snow, wind-blown dust, etc.), and whose temperature can be
maintained between +40 deg. F and +120 deg. F. (4.4 - 49°C)
If extended high humidity is expected to be a problem, all
exposed parts should be inspected before storage and all
surfaces that have the paint scratched, damaged, or worn
should be recoated with a water base, air dry enamel paint.
All surfaces should then be sprayed with a rust-inhibiting oil.
Pump should be stored in its original shipping container. On
initial start up, rotate impeller by hand to assure seal and
impeller rotate freely. If it is required that the pump be installed
and tested before the long term storage begins, such
installation will be allowed provided:
1.) The pump is not installed under water for more than
one (1) month.
2.) Immediately upon satisfactory completion of the test,
the pump is removed, thoroughly dried, repacked in the
original shipping container, and placed in a temperature
controlled storage area.
B-4) Service Centers:
For the location of the nearest Barnes Pumps Service Center,
check your Barnes Engineered catalog, your Barnes Pumps,
Inc. representative or Barnes Pumps, Inc. Service Department
in Piqua, Ohio, telephone [phone] or Crane Pumps &
Systems Canada, in Brampton, Ontario,
[phone].
SECTION C: INSTALLATION
C-1) Location:
These pumping units are self-contained and are especially
designed to handle septic tank effluent, nonexplosive and
noncorrosive liquids and shall NOT be installed in locations
classified as hazardous in accordance with the National
Electrical Code (NEC), ANSI/NFPA 70 or Canadian Electric
Code (CEC). They will provide sufficient pressure to pump
material through small diameter, pipe to gravity interceptors,
treatment plants or remote leach fields. Never install the
pump in a trench, ditch or hole with a dirt bottom; the legs will
sink into the dirt and the suction will become plugged.
C-1.1) Submergence:
THe pump should always be operated in the submerged
condition and the sump liquid level should never be less than
dimension "A" in Figure 1.
C-2) Discharge:
Discharge piping should be as short as possible. Both a check
valve and a shut-off valve are recommended for each pump
being used. The check valve is used to prevent backflow into
the sump.Excessive backflow can cause flooding and/or
damage to the pump. The shut-off valve is used to stop
system flow during pump or check valve servicing.
Barnes Effluent Pumps can be installed by one of two
methods: (1) the flex hose system, most commonly used in
interceptor tanks and (2) the stainless rail package and
stainless rail for concrete wet wells, designed to allow the
pump to be installed or removed without requiring personnel
to enter the wet well.

1.) Flex Hose System (Not Shown)- Connect the flex hose
assembly, as outlined in specifications (to include at least but
not limited to, flex hose, shut-off valve, check valve and fittings),
to the pump discharge. Attach lifting rope, chain or cable to
pump handle. Next lower pump into basin and connect flex
hose assembly to discharge coupling on basin. Now connect
power and control (optional) cables to junction box or control
panel depending on the system design.
2a.) Stainless Rail Package (Not Shown)- The package
system comes complete and ready to place into ground as
outlined in the project specifications. The moveable portion of
the Break Away Fitting (BAF), check valve, piping and guide
bracket comes assembled on the pump along with the lifting
rope. Insert pump bracket and moveable portion of BAF into
the guide channel and lower pump into basin (DO NOT DROP).
Now connect power and control (optional) cables to the junction
box or control panel depending on system design.
C-3) Liquid Level Controls:
The level controls are to be supported by a mounting bracket
that is attached to the sump wall, cover or junction box. Cord
grips are used to hold the cords in place on the mounting
bracket. The control level can be changed by loosening the grip
and adjusting the cord length as per the plans and
specifications. Be certain that the level controls cannot hang up
or foul in it’s swing and that the pump is completely submerged
when the level control is in the "Off" mode.
C-4) Electrical Connections:
WARNING!
ALL MODEL PUMPS AND CONTROL PANELS MUST
BE PROPERLY GROUNDED PER THE NATIONAL
ELECTRIC CODE OR THE CANADIAN ELECTRIC
CODE, STATE, PROVINCE AND LOCAL CODES.
IMPROPER GROUNDING VOIDS WARRANTY.
C-4.1) Power & Control Cable:
The cord assembly mounted to the pump must not be modified
in any way except for shortening to a specific application. Any
splice between the pump and the control panel must be made
in accordance with all applicable electric codes. It is
recommended that a junction box, be mounted outside the
sump or be of at least Nema 4 (EEMAC-4) construction if
located within the wet well. DO NOT USE THE POWER OR
CONTROL CABLE TO LIFT PUMP!
C-4.2) Overload Protection:
C-4.2-1) Three Phase (optional)- The normally closed (N/C)
thermal sensor is embedded in the motor windings and will
detect excessive heat in the event an overload condition
occurs. The thermal sensor will trip when the windings become
too hot and will automatically reset itself when the pump motor
cools to a safe temperature.
It is recommended that the thermal sensor be connected in
series to an alarm device to alert the operator of an
overtemperature condition and/or the motor starter coil to stop
the pump. In the event of an overtemperature, the source of
this condition should be determined and rectified immediately.
Thermal protection shall not be used as a motor overload
device. A separate motor overload device must be provided in
accordance with NEC or CEC codes.
DO NOT LET THE PUMP CYCLE OR RUN IF AN OVERLOAD
CONDITION OCCURS !
C-4.2-2) Single Phase (standard)- The type of in-winding
overload protector used is referred to as an inherent
overheating protector and operates on the combined effect of
temperature and current. This means that the overload
protector will trip out and shut the pump off if the windings
become too hot, or the load current passing through them
becomes too high. It will then automatically reset and start the
pump after the motor cools to a safe temperature. In the event
of an overload, the source of this condition should be
determined and rectified immediately.
DO NOT LET THE PUMP CYCLE OR RUN IF AN OVERLOAD
CONDITION OCCURS !
If current through the temperature sensor exceeds the values
listed, an intermediate control circuit relay must be used to
reduce the current or the sensor will not work properly.

C-4.3) Moisture Sensors: (Optional)
A normally open (N/O) detector is installed in the pump seal
chamber which will detect any moisture present. It is
recommended that this detector be connected in series to an
alarm device or the motor starter coil to alert the operator that
a moisture detect has occurred. In the event of a moisture
detect, check the individual moisture sensor probe leads for
continuity, ( ∞ resistance = no moisture ) and the junction
box/control box for moisture content. The above situations may
induce a false signal in the moisture detecting circuit. If none
of the above test prove conclusive, the pump(s) should be
pulled and the source of the failure identified and repaired.
IF A MOISTURE DETECT HAS OCCURRED SCHEDULE
MAINTENANCE AS SOON AS POSSIBLE.
C-4.4) Wire Size:
Consult a qualified electrician for proper wire size if additional
power cable length is required. See table for electrical
information.

SECTION: D START-UP OPERATION
D-1) Check Voltage and Phase:
Before operating pump, compare the voltage and phase information
stamped on the pump identification plate to the available power.
D-2) Check Pump Rotation:
Before putting pump into service for the first time, the motor rotation
must be checked. Improper motor rotation can result in poor pump
performance and can damage the motor and/or pump. To check the
rotation, suspend the pump freely, momentarily apply power and
observe the "kickback". "Kickback" should always be in a
counter-clockwise direction as viewed from the top of the pump
motor housing.
D-2.1) Incorrect Rotation for Three-Phase Pumps:
In the event that the rotation is incorrect for a three-phase installation,
interchange any two power cable leads at the control box. DO NOT
change leads in the cable housing in the motor. Recheck the
"kickback" rotation again by momentarily applying power.
D-2.2) Incorrect Rotation for Single-Phase Pumps:
In the unlikely event that the rotation is incorrect for a single phase
pump, contact a Barnes Pumps Service Center.
D-3) Start-Up Report:
Included at the end of this manual are two start-up report sheets,
these sheets are to be completed as applicable. Return one copy to
Barnes Pumps, Inc. and store the second in the control panel or with
the pump manual if no control panel is used. It is important to record
this data at initial start-up since it will be useful to refer to should
servicing the pump be required in the future.
D-3.1) Identification Plate:
Record the numbers from the pump identification plate on both
START-UP REPORTS provided at the end of the manual for future
reference.
D-3.2) Insulation Test:
Before the pump is put into service, an insulation (megger) test
should be performed on the motor. The resistance values (ohms) as
well as the voltage (volts) and current (amps) should be recorded
on the start-up report.
D-3.3) Pump-Down Test:
After the pump has been properly wired and lowered into the basin,
sump or lift station, it is advisable to check the system by filling with
liquid and allowing the pump to operate through its pumping cycle.
The time needed to empty the system, or pump-down time along
with the volume of water, should be recorded on the start-up report.
SECTION E: PREVENTATIVE MAINTENANCE
As the motor is oil filled, no lubrication or other maintenance is
required, and generally Barnes Pumps will give very reliable service
and can be expected to operate for years of normal sewage pumping
without failing. However, as with any mechanical piece of equipment
a preventive maintenance program is recommended and suggested
to include the following checks:
1) Inspect motor chamber for oil level and contamination and
repair as required per section F-1.
2) Inspect impeller and body for excessive build-up or clogging and
repair as required per section F-2.
3) Inspect seal for wear or leakage and repair as required per
section F-3.
4) Inspect motor and bearings and replace as required per
section F-4.

SECTION F: SERVICE AND REPAIR
NOTE: All item numbers in ( ) refer to Figures 9 & 10.
WARNING !
ELECTRICAL POWER TO THE PUMP MOTORS MUST
BE DISCONNECTED AND LOCKED OUT TO PREVENT
ANY DANGEROUS ELECTRICAL HAZARDS OR
PERSONNEL DANGER BEFORE ANY SERVICE WORK
IS DONE TO THE PUMP.
CAUTION !
OPERATING PUMP BUILDS UP HEAT AND
PRESSURE; ALLOW TIME FOR PUMP TO COOL TO
ROOM TEMPERATURE BEFORE HANDLING OR
SERVICING.
F-1) Lubrication:
Anytime the pump is removed from operation, the cooling oil
in the motor housing (5) should be checked visually for oil level
and contamination.
F-1.1) Checking Oil:
Motor Housing- To check oil, set unit upright. Remove pipe
plug (31). With a flashlight, visually inspect the oil in the motor
housing (5) to make sure it is clean and clear, light amber in
color and free from suspended particles. Milky white oil
indicates the presence of water. Oil level should be to the
midpoint of capacitor (2), see Fig. 9, when pump is in vertical
position.
F-1.2) Testing Oil:
1. Place pump on it’s side, remove pipe plug (31), from
motor housing (5) and drain oil into a clean, dry container.
2. Check oil for contamination using an oil tester with a range
to 30 Kilovolts breakdown.
3. If oil is found to be clean and uncontaminated (measure at
or above 15 KV. breakdown), refill the motor housing
as per section F-1.3.
4. If oil is found to be dirty or contaminated (or measures
below 15 KV. breakdown), the pump must be carefully
inspected for leaks at the shaft seal (10), cable assembly
(29), and pipe plug (31), O-rings (7) and pipe plug (19),
before refilling with oil. To locate the leak, perform a
pressure test as per section F-1.4. After leak is repaired,
refill with new oil as per section F-1.3.
F-1.3) Replacing Oil:
Motor Housing- Drain all oil from motor housing and dispose
of properly. Set unit upright and refill with (see parts list for
amount) new cooling oil as per Table 1. Fill to the midpoint of
capacitor (2) as an air space must remain in the top of the motor
housing to compensate for oil expansion (see Cross-section
Fig. 9). Apply pipe thread compound to threads of pipe plug
(31) then assemble to motor housing (5).
Seal Chamber- Set unit on its side with fill plug (19) downward,
remove plug (19) and drain all oil from seal chamber. Set unit
on its side, with plug (19) upward, and refill completely with
(see parts list for amount) new oil as per Table 1. Apply pipe
thread compound to threads of pipe plug (19) and assemble to
spacer (9).
WARNING !
DO NOT OVERFILL OIL
OVERFILLING OF MOTOR HOUSING WITH OIL CAN
CREATE EXCESSIVE AND DANGEROUS HYDRAULIC
PRESSURE WHICH CAN DESTROY THE PUMP AND
CREATE A HAZARD. OVERFILLING OIL VOIDS
WARRANTY.
F-1.4) Pressure Test:
Motor Housing- Before checking the pump for leaks around
the shaft seal, square rings, and cord inlet, the oil level should
be full as described in section F-1.3. Remove pipe plug (19)
from motor housing (5). Apply pipe sealant to pressure gauge
assembly and tighten into hole (see Fig. 2). Pressurize motor
housing to 10 P.S.I. Use a soap solution around the sealed
areas and inspect joints for "air bubbles". If, after five minutes,
the pressure is still holding constant, and no "bubbles" are
observed, slowly bleed the pressure and remove the gauge
assembly. Replace the pipe plug (19) using a sealant. If the
pressure does not hold, then the leak must be located and
repaired.
Seal Chamber- Remove pipe plug (19) from Intermediate
Coupling (9) and check that the seal chamber is full of oil. Apply
pipe sealant to pressure gauge assembly and tighten into hole
in Intermediate Coupling (9). Pressurize seal chamber to 10
P.S.I. and check for leaks as outlined above.

F-2) Impeller and Volute Service:
F-2.1) Disassembly and Inspection:
To clean out volute (13) or replace impeller (17) or replace
U-cup (16), disconnect power, remove hex nuts (22),
lockwashers (35) and cap screws (20), vertically lift motor and
seal plate assembly from body (13). Clean out body if
necessary. Check U-cup (16) for damage, if U-cup (16) needs
replacement, cut the U-cup from volute (13) and clean surface
of the bore. Clean and examine impeller (17), for cracks or
breakage and replace if required, inspect gasket (18) and
replace if cut or damaged. If the impeller (17) needs replacing,
turn pump upside down and remove cap screw (14) and
washers (15) from shaft. (Seal spring relaxes when impeller is
removed and may cause oil from lower seal to leak through).
Hold the motor shaft stationary with a flat screwdriver placed
in the slotted shaft end. Turn the impeller (17) counterclockwise
to loosen.
F-2.2) Reassembly:
To install impeller (17), screw impeller onto the shaft hand tight.
It is important that the spring of the lower shaft seal (10) seats
in the hub of the impeller (17). Place washers (15) onto cap
screw (14). Apply thread locking compound to the threads of
cap screw (14) and tighten into shaft. Rotate impeller to check
for binding.
Install U-cup (16) by first applying adhesive to bore of volute
(13). Be sure not to get adhesive on inside diameter of U-cup
(16). Position gasket (18) on volute flange and reposition volute
onto motor and impeller assembly, aligning for fasteners.
CAUTION: When assembling volute (13) to the rest of the
pump be sure the inside lip of the U-cup (16) is not pushed out
of place. (See Figure 3.) Position cap screws (20) through
volute (13) and motor housing (5). Place lockwashers (35) and
hex nuts (22) onto cap screws (20) and tighten.
F-3) Shaft Seal Service:
CAUTION !
HANDLE SEAL PARTS WITH EXTREME CARE. DO
NOT SCRATCH OR MAR LAPPED SURFACES.
F-3.1) Disassembly and Inspection:
Outer Seal- To expose shaft seal (10) for examination
disassemble volute and impeller as outlined in paragraph
F-2.1. Drain oil from seal cavity as outlined in paragraph F-1.3.
If further repair is required remove retaining ring (10d), spring
(10c) and rotating member (10b) from shaft (see Fig. 4).
Examine all seal parts and especially contact faces. Inspect
seal for signs of wear such as uneven wear pattern on

Inner Seal- To expose inner shaft seal (10) for examination,
remove outer seal as outlined above. Remove socket head cap
screws (8) and (38). Lift seal plate (12) and square-ring (7) from
intermediate coupling (9). If replacement is required, drain oil
from motor housing per paragraph F-1.3, then remove retaining
ring (11), retaining ring (10b), spring (10c) and rotating member
(10d) from shaft. Examine as outlined in outer seal paragraph.
If replacing seal, remove stationary (10a) by prying out with flat
screw driver.
F-3.2) Reassembly:
Inner Seal- Clean and oil seal cavities in seal plate (12). Lightly
oil (DO NOT use grease) outer surface of stationary member
(10a). Press stationary member (10a) firmly into intermediate
coupling (9), using a seal pusher (see parts list- seal tool kit).
Nothing but the seal pusher is to come in contact with seal face
(see Fig. 5).
IMPORTANT !
DO NOT HAMMER ON THE SEAL PUSHER- IT WILL
DAMAGE THE SEAL FACE.
Make sure the stationary member is in straight. Slide a bullet
(see parts list-seal tool kit) over motor shaft. Lightly oil (DO
NOT use grease) shaft, bullet and inner surface of bellows on
rotating member (10b) see Fig. 6. With lapped surface of
rotating member (10b) facing inward toward stationary
member (10a), slide rotating member (10b) over bullet and
onto shaft, using seal pusher, until lapped faces of (10a) and
(10b) are together (see Fig. 4).
IMPORTANT !
IT IS EXTREMELY IMPORTANT TO KEEP SEAL FACES
CLEAN DURING ASSEMBLY. DIRT PARTICLES
LODGED BETWEEN THESE FACES WILL CAUSE THE
SEAL TO LEAK.

(9) and lower seal plate (12) onto intermediate coupling (9).
Insert socket head cap screws (8) and (38) and torque to 60
inch pounds. Repeat insertion of seal for outer seal.
Assemble impeller and volute as outlined in paragraph F-2.2.
Replace oil as outlined in paragraph F-1.3.
F-4) Motor and Bearing Service
F-4.1) Disassembly and Inspection:
To examine or replace the motor (4), capacitor (2) and
bearing (23), disassemble volute and impeller as outlined in
paragraph F-2.1 and disassemble shaft seals as outlined in
paragraph F-3.1. Drain oil from motor and seal cavity as
outlined in paragraph F-1.3.
Remove gland nut (29b), friction rings (29c) and grommet
(29d) from motor housing (5). See Figure 8. Position unit
upright, using blocks to avoid resting unit on shaft. Vertically
lift motor housing (5) from intermediate coupling (9). Inspect
square-ring (7) for damage or cuts. Remove cable assembly
(29) by disconnecting connectors (27) and ground screw (26)
from motor (4). If pump is equipped with moisture sensors,
disconnect connectors (27) from wires (38). Disconnect
capacitor leads and terminal insulators (28) from capacitor.
Remove motor bolts and lift motor stator from intermediate
coupling (9). To remove ball bearing (23) loosen conduit
bushing (6) and pull motor shaft and ball bearing from
intermediate coupling (9). Examine bearing (23) and replace
if required. If replacement is required, remove bearing (23)
from motor shaft using a wheel puller or arbor press. Inspect
motor windings for shorts and check resistance values.
Check rotor for wear. If rotor or stator windings are defective
the complete motor must be replaced. Check motor capacitor
(2) with an Ohm meter by first grounding the capacitor by
placing a screwdriver across both terminals and then
removing screwdriver. Connect Ohm meter (set on high
scale) to terminals, if needle moves to infinity ( ∞ ) then drifts
back, the capacitor is good. If needle does not move or moves
to infinity (∞) and does not drift back, replace capacitor (2). If
moisture sensors (optional) are damaged, remove machine
screws (39) and washers (40) from probes (37). Remove
probes (37) from intermediate coupling (9).
IMPORTANT !
ALL PARTS MUST BE CLEAN BEFORE
REASSEMBLY.
F-4.2) Reassembly:
Moisture Sensors- If pump is equipped with optional
moisture sensors, to reassemble, apply thread compound to
threads on probes (37) and install in intermediate coupling
(9). Connect wires (38) to probes (37) with washers (40) and
machine screws (39).
Bearings- When replacing bearing, be careful not to damage
the rotor or shaft threads. Clean the shaft thoroughly. Place
conduit bushing (6) and washer (25) over shaft. Apply
adhesive compound to shaft and press bearing (23) on,
positioning squarely on the shaft shoulder, applying force to
the inner race of bearing only.
Motor- Slide motor rotor and bearing (23) into intermediate
coupling (9). Place washer (25) over bearing and tighten
conduit bushing (6) on intermediate coupling (9). Set motor
stator over rotor being sure that stator drops flat against
register in intermediate coupling (9). Insert motor bolts in
motor and torque to 17 inch pounds. Reconnect capacitor
wires and terminal insulators (28) to capacitor. Make wire
connections per paragraph F-4.3. Set square-ring (7) in
groove on intermediate coupling (9), lower motor housing (5)
down onto intermediate coupling (9). Reassemble inner and
outer seals per paragraph F-3.2 and volute and impeller per
paragraph F-2.2.
F-4.3) Wiring Connections:
Check power cable (29) and control cable (32) for cracks or
damage and replace if required. When replacing cord (29) be
sure to check if pump has a three wire (standard) or five wire
(with optional moisture sensor) cable, on single phase
pumps. When replacing power cord (29) and/or control cord
(32) on three phase pumps be sure to check if pump has a
four wire power cable and/or (32) control is either 2 wire (for
tempeature only) or five wire cable (for moisture and
temperature sensors). Place parts (29b,c & d) on cable (29a).
Bring cord set (29) through opening in top of motor housing
(5), and reconnect motor leads to power cable (29) (three
wire) using connectors (27). See Figure 7. If pump is
equipped with moisture sensors, connect wires (38) to power
cable (29) (five wire) with connectors (27).

TROUBLESHOOTING
CAUTION ! Always disconnect the pump from the electrical power source before handling.
If the system fails to operate properly, carefully read instructions and perform maintenance recommendations.
If operating problems persist, the following chart may be of assistance in identifying and correcting them:
MATCH "CAUSE" NUMBER WITH CORRELATING "CORRECTION" NUMBER.
NOTE: Not all problems and correction will apply to each pump model.
PROBLEM CAUSE CORRECTION
Pump will not run. 1. Poor electrical connection, blown fuse,
tripped breaker or other interruption of
power; improper power supply.
2. Motor or switch inoperative (to isolate
cause, go to manual operation of pump).
2a. Float movement restricted.
2b. Switch will not activate pump or is
defective.
2c. Defective motor.
3. Insufficient liquid level.
1. Check all electrical connections for
security. Have electrician measure current
in motor leads, if current is within ±20% of
locked rotor Amps, impeller is probably
locked. If current is 0, overload may be
tripped. Remove power, allow pump to
cool, then recheck current.
2a. Reposition pump or clean basin as
required to provide adequate clearance for
float.
2b. Disconnect level control. Set
ohmmeter for a low range, such as 100
ohms full scale and connect to level control
leads. Actuate level control manually and
check to see that ohmmeter shows zero
ohms for closed switch and full scale for
open switch. (Float Switch).
2c. Check winding insulation (Megger
Test) and winding resistance. If check is
out side of range, dry and recheck. If still
defective, replace per service instructions.
3. Make sure liquid level is at least equal to
suggested turn-on point.
4. Recheck all sizing calculations to
determine proper pump size.
5. Check discharge line for restrictions,
including ice if line passes through or into
cold areas.
6. Remove and examine check valve for
proper installation and freedom of
operation.
7. Open valve.
8. Check impeller for freedom of operation,
security and condition. Clean impeller
cavity and inlet of any obstruction.
9. Loosen union slightly to allow trappedair
to escape.Verify that turn-off level of switch
is set so that impeller cavity is always
flooded. Clean vent hole.
10. Check rotation. If power supply is three
phase, reverse any two of three power
supply leads to ensure proper impeller
rotation.
11. Repair fixtures as required to eliminate
leakage.
12. Check pump temperature limits & fluid
temperature.
13. Replace portion of discharge pipe with
flexible connector.
14. Turn to automatic position.
15. Check for leaks around basin inlet and
outlets.
Pump will not turn off. 2a. Float movement restricted.
2b. Switch will not activate pump or is
defective.
4. Excessive inflow or pump not properly
sized for application.
9. Pump may be airlocked.
14. Switch is in "HAND" position.
Pump hums but doesn’t run. 1. Incorrect voltage.
8. Impeller jammed or loose on shaft, worn
or damaged, impeller cavity or inlet
plugged.
Pump delivers insufficient capacity. 1. Incorrect voltage.
4. Excessive inflow or pump not properly
sized for application.
5. Discharge restricted.
6. Check valve stuck closed or installed
backwards.
7. Shut-off valve closed.
8. Impeller jammed or loose on shaft, worn
or damaged, impeller cavity or inlet
plugged.
9. Pump may be airlocked.
10. Pump running backwards.
Pump cycles too frequently or runs
periodically when fixtures are not in use.
6. Check valve stuck closed or installed
backwards.
11. Fixtures are leaking.
15. Ground water entering basin.
Pump shuts off and turns on independent
of switch. (trips thermal overload
protector). CAUTION! Pump may start
unexpectedly. Disconnect power supply.
NOTE: Some pumps DO NOT have
thermal overload protection on the motor.
Check pump specifications to determine.
1. Incorrect voltage.
4. Excessive inflow or pump not properly
sized for application.
8. Impeller jammed, loose on shaft, worn
or damaged, impeller cavity or inlet
plugged.
12. Excessive water temperature
(internal protection only).
Pump operates noisily or vibrates
excessively.
2c. Worn bearings, motor shaft bent.
8. Debris in impeller cavity or broken
impeller.
10. Pump running backwards.
13. Piping attachments to building
structure too rigid or too loose.
