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:
These self-contained pumping units are recommended
for use in a Dry Pit application. This pump is designed to
pump sewage, effl uent, wastewater or other nonexplosive
liquids. Never install the pump in a trench, ditch or hole
with a dirt bottom, the pump will sink into the dirt and the
suction will become plugged.
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) Thermal Protection:
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
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.
