SECTION B: GENERAL INFORMATION
The sump or basin shall be vented in accordance with
local plumbing codes. Provide proper sump diameter of
approx. 18” (457mm) minimum and depth of approx. 20”
(508mm)minimum to allow the pump and switch to operate
without restriction. The float switch should not come in
contact with side or bottom of sump. Make sure sump
is free of string, cloth, nails, gravel, etc. before installing
pump. Never install the pump in a trench, ditch, or hole
with a dirt bottom where the suction will become plugged.
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.
C-1.1) Submergence:
The minimum sump liquid level should never be less than
4 inches (102mm) above the pump bottom.
Check local codes and requirements before installation.
Servicing should be performed by knowledgeable pump
service contractors or authorized service stations.
C-2) Discharge:
Discharge piping should be as short as possible. The
installation of a check valve in the discharge piping is
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 pump is packaged ready for installation and no
connections 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
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 crating, do not lose or
misplace.
C-3) Liquid Level Controls:
Figure 2 shows a typical installation for a submersible
pump using a piggy-back wide angle level control mounted
to the pump.
B-3) Storage:
Short Term- Barnes Pumps are manufactured for efficient
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,

FIGURE 2
General Comments:
1) Never work in the sump with the power on.
SECTION C: INSTALLATION
2) Level controls are factory set. 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.
C-1) Location:
These pumping units are self-contained and are
recommended for use in a sump or basin. This pump is
designed to pump rain water or light 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 the
Canadian Electrical Code (CEC).
3) Plug the pump plug into a GFI receptacle. One cycle
of operation should be observed, so that any potential
problems can be corrected.

SECTION D: SERVICE AND REPAIR
Manual
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.
Automatic
D-1) Bottom Plate:
Remove screws, and remove bottom plate from volute and
remove volute. Clean and examine impeller. If impeller
vanes are clogged, or it is excessively worn or broken, the
impeller should be replaced.
FIGURE 3
Figure 3 shows a typical connection for pumps with
thepiggy-back plug, for manual and automatic operations.
D-2) Impeller:
After removing the bottom plate the impeller may be
removed by turning impeller counterclockwise to remove
from shaft. When reassembling the impeller, turn the
impeller clockwise until it bottoms against shaft. Replace
volute, bottom plate, and screws.
Automatic - Plug float cord into GFI outlet, then plug
pump cord into float cord.
Manual - Plug pump cord directly into GFI outlet.

IMPORTANT! - When Installing Vertical Float
Pumps, Check To Be Sure Float Is Not Hung
Up On Top Of Volute Housing.
SUPPLIER
C-4) Electrical Connections:
C-4.1) Power Cable:
The cord assembly mounted to the pump must not be
modified in any way. This pump comes complete with a
3 wire cord and 3 prong grounded plug that must be connected into a 3 wire grounded Ground Fault receptacle.
DO NOT remove ground pin from electrical plug. It is NOT
recommended to use an extension cord with these pumps.
DO NOT USE THE POWER CABLE TO LIFT PUMP.
C-4.2) Overload Protection:
Automatic thermal overload protects the sealed-in-oil
motor. Running dry may overheat the motor and trip the
overload. 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 rectified immediately. DO NOT LET THE
PUMP CYCLE OR RUN IF AN OVERLOAD CONDITION
OCCURS !
