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 :
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 opera-
tor 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 immediately.
DO
NOT LET THE PUMP CYCLE OR RUN IF AN OVERLOAD
CONDITION OCCURS !
C-4.3) Moisture Sensors:
A normally open (N/O) detector is installed in the pump seal
chamber which will detect any moisture present. It is recom-
mended that this detector be connected in series to an alarm
device or the motor starter coil to alert the operator that a
moisture detect has occurred. In the event of a moisture
detect, check the individual moisture sensor probe leads for
continuity, (
∞
resistance = no moisture ) and the junction
box/control box for moisture content. The above situations
may induce a false signal in the moisture detecting circuit. If
none of the above test prove conclusive, the pump(s) should
be pulled and the source of the failure identifi ed and repaired.
IF A MOISTURE DETECT HAS OCCURRED SCHEDULE
MAINTENANCE AS SOON AS POSSIBLE.
