Receiving inspection
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.
Storage
Any product that is stored for a
period longer than six (6) months
from the date of purchase should be
bench tested prior to installation. A
bench test consists of, checking the
impeller to assure it is free turning
and a run test to assure the motor
(and switch if provided) operate
properly.
Controls
Manual models require a separate
approved pump control device or
panel for automatic operation. Be
sure the electrical specification of the
control selected properly match the
electrical specifications of the pump.
Submergence
The pump should always be
operated in the submerged
condition. The minimum sump liquid
level should never be less than above
the pump’s volute (See Figure 1).
Discharge Piping
Discharge piping should be as short
as possible and sized no smaller than
the pump discharge. Do not reduce
the discharge pipe size below that
which is provided on the pump.
Both a check valve and a shut-off
valve are recommended for each
pump. The check valve is used to
prevent backflow into the sump. The
shut-off valve is used to manually
stop system low during pump
servicing.
Liquid Level Controls
The level control(s) should be
mounted on the discharge piping, a
cable rack or float pole. The level
control should have adequate
clearance so it cannot hang up in it’s
swing and that the pump is
completely submerged when the
level control is in the "Off" mode. By
adjusting the cord tether the control
level can be changed. One cycle of
operation should be observed, so
that any potential problems can be
corrected.
Electrical Connections
Power cable:
The power cable 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 the electric codes. It is
recommended that a junction box, if
used, be mounted outside the sump
or be of at a minimum Nema 4
construction if located within the wet
well. DO NOT USE THE POWER
CABLE TO LIFT PUMP.
Overload Protection:
Single Phase - The stator 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.
03
Recommendations and Warnings
The sump, basin or lift station shall
be sealed and vented in accordance
with local plumbing codes. This
pump is designed to pump
sewage, effluent or wastewater,
non-explosive and non-corrosive
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).
The pump should never be installed
in a trench, ditch, or hole with a dirt
bottom. The legs will sink into the
dirt and the suction will become
plugged.
The installation should be at a
sufficient depth to ensure that all
plumbing is below the frost line. If
this is not feasible, remove the check
valve and size the basin to
accommodate the additional
backflow volume.
barmesapumps.com
Installation
There are two methods of installing
effluent pumps:
1. In a Flex-Hose system, most
commonly used in interceptor
tanks, and
2. A slide rail in a package system or
concrete wet well, which allows
the pump(s) to be installed or
removed without requiring
personnel to enter the wet well.
It is recommended that the level
control float should be set to insure
that the liquid in the sump never
drops below the top of the motor
housing or a minimum level of 7"
above the basin floor.
Always rely upon a Certified
Electrician for installation.

IMPORTANT! - The overload 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 corrected
immediately.
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.

Installation & Service
DO NOT ALLOW THE
PUMP TO CYCLE OR RUN IF AN
OVERLOAD CONDITION OCCURS.
WARNING
Pre-Operation
1.Check Voltage and Phase -
Compare the voltage and phase
information stamped on the
pump name plate.
3.Name Plate - Record the
information from the pump name
plate to drawing in front of
manual for future reference.
a)Inspect motor chamber for oil
level and contamination.
b)Inspect impeller and body for
excessive build-up or clogging.
c)Inspect motor, bearings and shaft
seal for wear or leakage.
No lubrication or maintenance is
required. Perform the following
checks when pump is removed from
operation or when pump
performance deteriorates:
Maintenance
NOTE: Item numbers in ( ) refer to
Figure 6 and 7.
Servicing
After leak is repaired, dispose of old
oil properly, and refill with new oil.
4.Insulation Test - An insulation
(megger) test should be
performed on the motor. Before
the pump is put into service. The
resistance values (ohms) as well
as the voltage (volts) and current
(amps) should be recorded.
5.Pump-Down Test - Be sure pump
has been properly wired, lowered
into the basin, sump or lift station,
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.
2.Check Pump Rotation - Improper
motor rotation can result in poor
pump performance and can
damage the motor and/or pump.
Incorrect rotation for Single-Phase
pumps is unlikely. Impeller
rotation is counter-clockwise as
viewed from bottom of pump.
Cooling Oil - Anytime the pump is
removed from operation, the cooling
oil in the motor housing should be
checked visually for oil level and
contamination. To check oil, set unit
upright. Remove pipe plug (16) from
housing (4). With a flashlight, visually
inspect the oil in the housing (4) 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 just above the motor
when pump is in vertical position.
Oil Testing
ŸDrain oil into a clean, dry
container by placing pump on it’s
side, remove pipe plug (16), from
housing (4).
ŸCheck oil for contamination using
an oil tester with a range to 30
kilovolts breakdown.
ŸIf oil is found to be clean and
uncontaminated (measuring
above 15 kV breakdown), refill the
housing.
ŸIf 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, cable
assembly, square ring and pipe
plug, before refilling with oil. To
locate the leak, perform a
pressure test.
barmesapumps.com

Pressure Test (If oil has been
drained) - Remove pipe plug (16)
from housing (4). Apply pipe sealant
to pressure gauge assembly and
tighten into hole. Pressurize motor
housing to 10 PSI. Use 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 oil. Leek must be
located and repaired if pressure does
not hold.
Pressure Test (If oil has NOT been
drained) - Oil should be at normal
level. Remove pipe plug (16) from
housing (4). Apply pipe sealant to
pressure gauge assembly and tighten
into hole. Pressurize motor housing
to 10 PSI. Use soap solution around
the sealed areas above the oil level
and inspect joints for "air bubbles".
For sealed areas below oil level, leeks
will seep oil. If, after five minutes, the
pressure is still holding constant, and
no "bubbles", oil seepage is
observed, slowly bleed the pressure
and remove the gauge assembly.
Replace oil. Leek must be located and
repaired if pressure does not hold.
Oil Replacement - Set unit upright
and refill with new cooling oil as per
table below. Fill to just above motor,
but below capacitor as an air space
must remain in the top of the
housing to compensate for oil
expansion. Apply pipe thread
compound to threads of pipe plug
(16) then assemble to housing (4).

Risk of electric shock. Always disconnect the pump from the power source before handling inspections or repairs.
Symptom Possible Cause(s) Corrective Action
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 (go to manual
operation)
2a. Float movement restricted
2b. Switch will not activate pump or is defective
2c. Defective motor
3. Insuffi 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 re-check current.
2a. Reposition pump or clean basin as required to
provide adaquate clearance for float
2b. Disconnect level control. Set ohmmeter for a
low rang, 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 re-check. If still defective, replace per
service instructions.
3. Make sure liquid level is above the pump
4. Re-check 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 trapped air to
escape. Verify that turn-off level of switch is set
so that the suction 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 and fluid
temperature
13. Replace portion of discharge pipe with flexible
connector or tighten existing piping.
14. Turn to automatic position
