SECTION B: GENERAL INFORMATION
B-1) To the Purchaser:
Congratulations! You are the owner of one of the nest pumps
on the market today. CP&S 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
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, le 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- CP&S Pumps are manufactured for e󰀩cient
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 unit 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). 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 Service Center, check
your Barnes representative or Crane Pumps & Systems, 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
recommended for use in a sump, lift station or basin. The
sump, lift station or basin shall be vented in accordance
with local plumbing codes. This pump is designed to pump
sewage, e󰀪uent, or other nonexplosive or noncorrosive
wastewater. and shall NOT be installed in locations classied
as hazardous in accordance with the National Electrical Code
(NEC), ANSI/NFPA 70 or The Canadian Electrical Code.
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:
It is recommended that the pump be operated in the
submerged condition and the sump liquid level should never
be less than dimension “A” in Fig. 1.
C-2) Discharge:
Discharge piping should be as short as possible. Both a
check valve and a shut-o󰀨 valve are recommended for each
pump being used. The check valve is used to prevent back-
ow into the sump. Excessive backow can cause ooding
and/or damage to the pump. The shut-o󰀨 valve is used to
stop system ow during pump or check valve servicing.
Barnes Pumps supplies a breakaway tting discharge system
designed to allow the submersible wastewater pump to be
installed or removed without requiring personnel to enter the
wet well.
Place the Break Away Fitting (BAF) in position. Temporarily
secure the guide rails in the upper mounting brackets and
locate the base on the bottom of the wet well. Level the base
with grout and/or shims. Install the intermediate support
brackets, if required. Make sure the rails are in a true vertical
position so the pump will clear the access opening and
will slide freely down the rails into place on the discharge
stationary tting. Once the rails are in proper alignment, bolt
the base into the oor of the station and connect the discharge
pipe to the elbow.
Connect the movable portion and other supplied ttings of the
BAF onto the pump and lower into wet well. See the Break
Away Fitting manual for more information.
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
specications. 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 “O󰀨” mode.

C-4) Electrical Connections:
C-4.1) Power & Control Cords:
The cord assembly mounted to the pump must not be modied
in any way except for shortening to a specic 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, if used, 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 CORDS TO LIFT PUMP. NOTE: THE WHITE
WIRE IS NOT A NEUTRAL OR GROUND LEAD. THE
BLACK, WHITE AND RED LEADS ARE POWER CARRYING
CONDUCTORS. THE GREEN LEAD IS FOR CONNECTION
TO GROUND.
C-4.2) Overload Protection :
C-4.2-1) Three Phase - 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 overload condition, and/or the motor starter coil to stop
the pump. In the event of an overload, the source of this
condition should be determined and rectied immediately. DO
NOT LET THE PUMP CYCLE OR RUN IF AN OVERLOAD
CONDITION OCCURS !
C-4.2-2) Single Phase - The type of in-winding overload
protector used is referred to as an inherent overheating
protector and operates on the combined e󰀨ect of temperature
and current. This means that the overload protector will trip out
and shut the pump o󰀨 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 up after the motor
cools to a safe temperature. In the event of an overload, the
source of this condition should be determined and rectied
immediately. DO NOT LET THE PUMP CYCLE OR RUN IF
AN OVERLOAD CONDITION OCCURS !
NOTE: Single phase pumps can be orederd with an optional
Thermal Sensor as well as the standard in winding overload
protection.
C-4.3) Moisture Sensors:
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 identied and repaired.
IF A MOISTURE DETECT HAS OCCURRED SCHEDULE
MAINTENANCE AS SOON AS POSSIBLE.
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.

SECTION: D START-UP OPERATION
D-1) Check Voltage and Phase:
Before operating pump, compare the voltage and phase
information stamped on the pump identication plate to the
available power.
D-2) Check Pump Rotation:
Before putting pump into service for the rst 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 Service Center.
D-3) Start-Up Report:
Included at the end of this manual is a start-up report sheet,
this sheet is to be completed as applicable. Return one copy
to Barnes 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) Identication Plate:
Record the numbers from the pump identication 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 lling 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 lled, no lubrication or other maintenance
is required, and generally Barnes Pumps will give very
reliable service and can be expected to operate for years on
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 and seal chambers 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 motor and bearings and replace as required per
section F-3.
4) Inspect seal and diaphragm for wear or leakage and repair
as required per section F-4.
SECTION F: SERVICE AND REPAIR
NOTE: All item numbers in ( ) refer to Figures 9 & 10,
3450RPM and Figures 11 & 12 , 1750RPM.
F-1) Lubrication:
Anytime the pump is removed from operation the cooling oil
in the motor housing (2) and seal chamber, must be checked
visually for oil level and contamination.
F-1.1) Checking Oil:
Motor Housing - To check oil, set unit upright. Remove cap
screws (6) and lockwashers (4), lift conduit box assembly (9)
from motor housing (2) but DO NOT disconnect conduit box
wiring from motor leads. With a ashlight, visually inspect the
oil in the motor housing (2) to make sure it is clean, clear and
that oil level is above all internal componentry.
Seal Chamber - Place pump on its side with the square
head pipe cap (22) downward, remove pipe cap (22) and
drain oil from the seal chamber. If the oil is found to contain
considerable water or other contamination or little oil drains
out, the shaft seal (38) and diaphragm (31) should be
inspected and replaced if required.
F-1.2) Testing Oil:
1. Place pump on it’s side, remove cap screws (6) and
lockwashers (4), lift conduit box assembly (9) from
motor housing (2) and drain oil into a clean, dry container.
In separate container drain seal chamber by removing
pipe cap (22).
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
above 15 KV. breakdown), rell the motor housing and
seal chamber as per section F-1.3.
4. If oil is found to be dirty or contaminated (or measures
below 15 KV. breakdown), the the pump must be carefully
inspected for leaks at the shaft seal (38), conduit box
assembly (9), diaphragm (31), O-rings (10) and (36),
pipe cap (22) and pipe plug (5) before relling with oil.
To locate the leak, perform a pressure test as per
section F-1.4.
After leak is repaired, rell 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. Rell with (see parts list for amount) new
cooling oil as per Table 1. An air space must remain in the top
of the motor housing to compensate for oil expansion (see
Fig. 9 or 11). Set unit upright and ll only until the motor, as
viewed through the conduit box opening, is just covered and
no more. Reassemble the O-ring (10), conduit box assembly
(9), cap screws (6) and lockwashers (4), apply Locktite (47)
to each cap screw (6) thread before installing. Torque cap
screws (6) to 17.5 ft, lb.
Seal Chamber - Rell chamber completely full with new
cooling oil per Table 1 or reuse the uncontaminated oil.

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
(5) and lifting handle (7) from motor housing (2).Apply pipe
sealant to pressure gauge assembly and tighten into pipe
plug 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 ve 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 using a sealant. If the pressure does not hold,
then the leak must be located.
Seal Chamber - Remove pipe cap (22) and pipe plug (21)
from Bearing Bracket (20) and check that seal chamber is
full of oil. Apply pipe sealant to pressure gauge assembly
and tighten into hole in bearing bracket (20). Pressurize seal
chamber to 10 PSI and check for leaks as outlined above.
Caution ! - Pressure builds up extremely
fast, increase pressure by “tapping” air
nozzle. Too much pressure will damage
seal. DO NOT exceed 10 P.S.I. in motor
housing & 10 P.S.I. in seal chamber.

To clean out volute (25), disconnect power, remove hex nuts
(19), lockwashers (18) and socket head cap screws (42),
vertically lift motor and seal assembly from body (25). Clean
out body if necessary. Clean and examine impeller (27) for
pitting or wear, replace if required. Inspect Square Ring (36)
and replace if cut or damaged.
If impeller (27) requires replacing, remove cap screw (33)
and washer (34). The impeller is keyed onto the shaft with a
square key (32) and to remove, pull impeller straight o󰀨 the
shaft using a wheel puller, if required. Before reinstalling,
check the motor shaft and impeller bore for damage.
F-2.2) Reassembly:
To install impeller (27), apply a thin lm of oil to motor shaft
and slide impeller straight onto shaft, keeping keyways lined
up. Drive key (32) into keyway. Locate washer (34), apply
Loctite (46) to shaft threads, thread hex nut (33) to shaft and
torque to 35 ft. lbs. Rotate impeller to check for binding.
Position square ring (36) on volute ange and install impeller
and motor housing over studs and onto volute (25). Apply
thread locking compound to threads of each stud (23) and
socket head cap screw (42). Thread nut (19) onto stud (23)
and thread socket head cap screw (42) into volute (25),
torque to 24 ft. lbs. Check for free rotation of motor and
impeller.
F-3) Motor and Bearing Service
F-3.1) Disassembly and Inspection:
To examine or replace the motor (1) and bearing (39),
disassemble pump, volute and impeller (as outlined in
paragraph F-2.1) and disassemble seal plate and shaft seal
(as outlined in paragraph F-4.1). Drain oil from motor as
outlined in paragraph F-1.3.
Position unit upright, using blocks to avoid resting unit on
shaft. After removal of cable and box assembly (9) from motor
housing (2), remove cable lead wires from motor lead wires
and moisture and temperature sensors wires (if equipped)
from control cable by unscrewing connectors (11) and (16).
The wiring connections should be noted to insure correct
connections when reassembling. Vertically lift the outside
motor housing (2) from bearing bracket (20) with lifting strap
(7). Inspect square ring (36) for damage or cuts. Remove the
upper motor bolts and lift upper end bell from motor (1).
Vertically lift stator. Inspect winding for shorts and resistance.
To test the temperature sensor (if equipped), check for
continuity between the black and white wires. If found to be
defective contact a motor service station or Barnes Pumps
service department. Remove retaining ring (28) from bearing
bracket (20) and pull motor rotor and lower bearing (39)
vertically from bearing bracket (20). Examine bearing (39)
and replace if required. If replacement is required, remove
retaining ring (29) from motor shaft and remove bearing (39)
from motor shaft using a wheel puller. Check rotor for wear.
If rotor or the stator windings are defective, the complete
motor must be replaced. Check motor capacitor (3) on single

until lapped faces of (38D) and (38E) are together (see Fig.
6).
Important ! - It is extremely important to keep
seal faces clean during assembly. Dirt particles
lodged between these faces will cause the seal to
leak.
Make sure driving lugs in retainer are matched in rotating
member. Place spring (38C) over shaft and in place on
rotating member (38E), making sure it is seated in retainer
and not cocked or resting on bellows tail. Re-oil shaft and
lightly oil inner surface of outboard rotating member (38B)
With tail section toward bearing bracket (20), slide rotating
member (38B) over bullet onto shaft with seal pusher until
retainer engages spring (38C) and spring is compressed

TROUBLE SHOOTING
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 corrections 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. Insu󰀩cient 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
oat.
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 outside
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 and
inlet of any obstruction.
9. Loosen union slightly to allow trapped air
to escape.Verify that turn-o󰀨 level of switch
is set so that the suction is always ooded.
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 xtures as required to eliminate
leakage.
12. Check pump temperature limits & uid
temperature.
13. Replace portion of discharge pipe with
exible connector.
14. Turn to automatic position.
15. Check for leaks around basin inlet and
outlets.
Pump will not turn o󰀨 2a. Float movement restricted.
2b. Switch will not activate pump or is defective.
4. Excessive inow or pump not properly sized
for application.
9. Pump may be airlocked
14. H-O-A switch on panel is in “HAND” position
Pump hums but does not run 1. Incorrect voltage
8. Impeller jammed or loose on shaft, worn or
damaged, impeller cavity or inlet plugged.
