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
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 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 b40°F and
+120°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.

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, effluent, or other nonexplosive or noncorrosive
wastewater. and shall NOT be installed in locations classified
as Class I Division 1 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” (see 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 back-
flow 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 Pumps offers a Break Away Fitting (BAF) discharge
system designed to allow the submersible wastewater pump
to be installed or removed without requiring personnel to enter
the wet well.
Place the 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 fitting. Once the rails are in
proper alignment, bolt the base into the floor of the station and
connect the discharge pipe to the elbow.
Connect the movable portion and other supplied fittings 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
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.
