SECTION B: GENERAL INFORMATION

 

B-1) To the Purchaser:

 

Congratulations! You are the owner of one of the finest 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, 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-

  CP&S  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 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 (937) 778-8947 

or Crane Pumps & Systems Canada, in Brampton, Ontario, 

(905) 457-6223.

SECTION C: INSTALLATION

C-1) Location:

 

These pumping units are self-contained and are especially 

designed to handle septic tank effluent or other nonexplosive 

or noncorrosive wastewater 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). They will provide sufficient 

pressure to pump material through small diameter pipe to 

gravity  interceptors,  treatment  plants  or  remote  leach  fields. 

Never install the pump in a trench, ditch or hole with gravel, 

stones, sand, or earth bottom; the legs will sink into the dirt 

and the suction will become plugged, or the pump impeller will 

be damaged. 

C-1.1) Submergence:

It is recommended that the pump be operated in the submerged 

condition and the sump liquid level should never be lower than 

the top of the pump. (see Fig 2)

 

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  backflow 

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 Effluent pumps can be installed by one of two methods: 

(1) the flex hose system, most commonly used in interceptor 

tanks and (2) the stainless rail package and stainless rail for 

concrete wet wells, designed to allow the pump to be installed 

or removed without requiring personnel to enter the wet well. 

Contact your local Barnes distributor for complete details.

Stainless Rail Package (Not Shown) - The package system 

comes complete and ready to place into the ground as outlined 

in the project specifications. The moveable portion of the Break 

Away Fitting (BAF), check valve, piping and guide bracket 

comes assembled on the pump along with the lifting cord. 

Insert pump bracket and moveable portion of BAF into the 

guide channel and lower pump into basin 

(DO NOT DROP)

Now connect power and control cords to the junction box or 

control panel depending on system design.

 

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.
