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 pumping units are self-contained and are recommended
for use in a sump, lift station or basin. This pump is designed
to pump sewage, effl uent, or other nonexplosive or noncor-
rosive wastewater and shall
NOT be installed in locations
classifi ed as hazardous in accordance with the National
Electrical Code (NEC), ANSI/NFPA 70 or 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-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-
fl 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) 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 speci-
fi cations. 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.
C-4) Electrical Connections:
C-4.1) Power & Control Cords:
The cord assembly mounted to the pump must not be modi-
fi 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 all applicable electric codes. It is
recommended that a junction box, if used, be mounted out-
side the sump or be of at least Nema 4 (EEMAC-4) construc-
tion if located within the wet well.
DO NOT USE THE POWER
OR CONTROL CORDS TO LIFT PUMP.
NOTE: The White Wire Is Not A Neutral Or Ground Lead.
The Black, White And Red Leads Are Power Carrying
Conductors. The Green Lead Is For Connection To
Ground.
C-4.2) Overload Protection :
C-4.2-1) Three Phase -
The normally closed (N/C) thermal
sensor is embedded in the motor windings and will detect
excessive heat in the event an overload condition occurs. The
thermal sensor will trip when the windings become too hot
and will automatically reset itself when the pump motor cools
to a safe temperature. It is recommended that the thermal
sensor be connected in series to an alarm device to alert the
operator of an overload condition, and/or the motor starter
coil to stop the pump. In the event of an overload, the source
of this condition should be determined and rectifi ed imme-
diately.
DO NOT LET THE PUMP CYCLE OR RUN IF AN
OVERLOAD CONDITION OCCURS !
C-4.2-2) Single Phase - The type of in-winding overload pro-
tector used is referred to as an inherent overheating protec-
tor 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 rectifi ed
immediately.
DO NOT LET THE PUMP CYCLE OR RUN IF
AN OVERLOAD CONDITION OCCURS !
NOTE: Single phase pumps can be orederd with an optional
Thermal Sensor as well as the standard in winding overload
protection.
