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. 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, fi le 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 effi cient 

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.

SECTION C: INSTALLATION

C-1) Location:

Water feeding and discharging for construction and civil 
works; Water supply and sewage works; Various kinds of 
industrial facilities; Housing and building facilities.

The pump can be used at almost all places but avoid 
continuous short-water operation at a sandy place, such may 
accelerate wear of the pump. Install the pump at a position 
where water can be collected most easily. When the pump is 
installed on soft muddy or sandy ground, lay wooden board 
or block under the body. 

DO NOT allow pump to be buried 

in mud or sand.

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” in Figure 1.

Before pumping fl uids other than water, consult the factory, 
giving fl uid, fl uid temperature, specifi c gravity, viscosity, 
capacity in USGPM and total head and/or pressure 
requirements, including friction loss through discharge line, 
fi ttings, valves, etc. Maximum fl uid temperature for sustained 
operation is 104°F (40°C) at specifi c gravity 1.0.

IMPORTANT ! - Pump should have strainer 
affi xed at all times. Inspect and clean the pump 
strainer periodically for maximum effi ciency and 
performance.

C-2) Discharge:

When any hose is used for connection, keep the hose as 
straight as possible as excessively bent hose reduces water 
quantity. Refrain from placing the discharge port (end of hose 
or pipe) under water. Inverse fl ow may sometimes be resulted 
due to siphon effect when the operation is stopped.

C-3) Electrical Connections:
C-3.1) Power Cord:

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 the electric code 
and all applicable state, province and local electric codes. It 
is recommended that a junction box, be mounted outside the 
sump or be of at least Nema 4 construction if located within 
the wet well. 

DO NOT USE THE POWER CORD TO LIFT 

PUMP!
