SECTION B: GENERAL INFORMATION
B-1) To The Purchaser:
Congratulations! You are the owner of one of the fi nest
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 com-
bine to produce a pump which will stand up to the toughest
applications.
Check local codes and requirements before installation.
Servicing should be performed by knowledgeable pump
service contractors or authorized service stations.
The pump is packaged ready for installation and no con-
nections or adjustments are necessary except for attaching
discharge piping and plugging in service cord.
B-2) Receiving:
Upon receiving the pump, it should be inspected for dam-
age or shortages. If damage has occurred, fi le a claim
immediately with the company that delivered the pump.
If the manual is removed from the crating, do not lose or
misplace.
B-3) Storage:
Short Term- Barnes Pumps are manufactured for effi cient
performance following long 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. Pump should be stored in its original shipping
container and before initial start up, rotate impeller by hand
to assure seal and impeller rotate freely.
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 (937) 778-8947 or Crane Pumps & Systems
Canada, Inc., Bramton, Ontario, (905) 457-6223.
SECTION C: INSTALLATION
C-1) Location:
These pumping units are self-contained and are
recommended for use in a sump or basin. The sump or
basin shall be vented in accordance with local plumbing
codes. This pump is designed to pump effl uent or
wastewater, nonexplosive and noncorrosive liquids and
shall NOT be installed in locations classifi 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:
The pump should always be operated in the submerged
condition. The minimum sump liquid level should never be
less than A Dimension, A = 6.50 inches on SEV Series and
A=4.50 inches on EHV Series above the pump bottom.
The recommended level should not drop below the top of
the motor housing (see Fig. 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
backfl ow into the sump. Excessive backfl ow can cause
fl ooding and/or damage to the pump. The shut-off valve
is used to stop system fl ow during pump or check valve
servicing.
C-3) Liquid Level Controls
Figure 2 shows a typical installation for any submersible
pump using a level control mounted to the discharge piping
with a piggy-back plug.
General Comments:
1) Never work in the sump with the power on.
2) Level controls are factory set for a pumping differential
of 9 inches. If that is the cycle desired, simply circle the
discharge pipe with the pipe mounting strap, feed the
end through the worm drive, and tighten with a
screwdriver. Be certain that the level control cannot
hang up or foul in its swing. Also, make certain the
pump impeller is still submerged when the level control
is in the “OFF” mode.
FIGURE 1
6
3) If a higher pump differential is needed, grip the cord
near the neck of the fl oat, then using the other hand,
exert a steady force on the lower edge of the cable
clamp. The cable clamp should slide up to the new
pivot point. Attach the level control to the discharge
hose in the manner described above.
4) Plug the level control plug into the GFI receptacle,
then plug the pump into the piggyback plug. One
cycle of operation should be observed , so that any
potential problems can be corrected.
5) It is recommended that the fl oat should be set to
insure that the sump well liquid level never drops
below the top of the motor housing or a minimum
level of 4.50 inches on EHV Series and 6.50 inches
on SEV Series above the pump bottom.
6.) Figure 3 shows a typical connection for pumps with
the wide angle fl oat and piggy-back plug, for manual
and automatic operations.
Automatic - Plug fl oat cord into GFI outlet, then plug
pump cord into fl oat cord.
Manual - Plug pump cord directly into GFI outlet.
C-4) Electrical Connections:
C-4.1) Power Cable:
The cord assembly mounted to the pump must not be
modifi ed in any way except for shortening to a specifi c
application. Any splice between the pump and the control
panel must be made in accordance with local 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 cable to lift pump.
WARNING! - The white wire is not a neutral or
ground lead, but a power carrying conductor.

C-4.2) Overload Protection:
Single Phase - 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 up
after the motor cools to a safe temperature. In the event
of an overload, the source of this condition should be
determined and rectifi ed 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.

SECTION D: SERVICE AND REPAIR
NOTE: All item numbers ( ) refer to Figure 8.
D-1) Lubrication:
Anytime the pump is removed from operation and at
least every twelve (12) months, the cooling oil in the
motor housing must be checked visually for oil level and
contamination.
D-1.1) Checking Oil:
To check oil, set unit upright. Remove pipe plug. With a
fl ashlight, visually inspect the oil in the motor housing to
make sure it is clean, clear and that the oil level is above
all internal componentry. If oil appears satisfactory, replace
pipe plug. If oil is low or appears contaminated, test oil as
per section D-1.2
D-1.2) Testing Oil:
1. Place pump on its side, remove pipe plug and drain oil
into 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
(measures above 15 kilovolts breakdown), refi ll the
motor housing with oil.
4. If oil is found to be dirty or contaminated (measures
below 15 kilovolts breakdown), then the pump must be
carefully inspected for leaks at the shaft seal (1), cord
inlet (2) , square ring and pipe plug before refi lling with
oil.
D-1.3 Replacing Oil in Motor Housing:
Drain all oil from motor housing and dispose of properly.
Refi ll with 32 ounces of new cooling oil as per Table 1. An
air space must remain in the top of the motor housing to
compensate for air expansion. Set unit upright and fi ll only
until oil level from top of pipe plug boss is 3” ± 1/4”.
WARNING ! - DO NOT overfi ll oil. Overfi lling of
motor housing with oil can create excessive
and dangerous hydraulic pressure which
can destroy the pump and create a hazard.
Overfi lling oil voids warranty.

E-1 SHAFT SEAL SERVICE:
Disconnect power, remove screws and lockwashers, and
vertically lift motor assembly from body. Clean out body if
necessary. Clean and examine impeller for pitting or wear.
The impeller is threaded onto the shaft and to remove,
unscrew impeller, holding shaft with a large screwdriver.
CAUTION: - Handle seal parts with extreme
care. DO NOT scratch or mar lapped surfaces.
To expose shaft seal (1) disassemble volute and impeller
as outlined in above paragraph. Remove rotating member
(1b) 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 stationary members,
chips and scratches on either seal face. DO NOT
interchange seal components, replace the entire shaft
seal (1). If replacing seal, remove stationary (1a) by prying
out with fl at screw driver.
Clean and oil seal cavities in lower motor housing. Lightly
oil (DO NOT use grease) outer surface of stationary
member (1a). Press stationary member (1a) fi rmly into
lower motor housing, using a seal pusher, 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 (1b) See Fig. 6. With lapped
surface of rotating member (1b) facing inward toward
stationary member (1a), slide rotating member (1b) over
bullet and onto shaft, using seal pusher, until lapped faces
of (1a) and (1b) are together (See Fig. 4).
It is extremely important to keep seal faces clean during
assembly. Dirt particles lodged between these faces will
cause the seal to leak. Place spring (1b) over shaft and in
place on rotating member (1c), making sure it is seated.
Slide retaining ring (1a) over shaft and let rest on spring
(1b).
Before installing impeller, inspect threads on shaft and
impeller to assure that they are clean. Apply a thread-
locking compound to shaft threads and screw impeller
onto shaft and tighten. Rotate impeller to check for
binding. Install motor housing assembly on pump body.
Apply thread locking compound to each cap screw, thread
into body with lockwashers, and torque to 11 ft. lbs. Check
for free rotation of impeller. Assemble impeller and volute
