C-3) Electrical Connections:
WARNING ! - All model pumps and control
panels must be properly grounded per The
National Electric Code or The Canadian Electrical
Code, State, Province and Local Codes. improper
grounding voids warranty.
C-3.1) Power & Control Cables:
The cord assembly mounted to the pump must
NOT
be
modified in any way except for shortening to a specific
application. Any splice between the pump and the control
panel must be made in accordance with the National
Electric Code or the Canadian 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 (EEMAC-4) construction if
located within the wet well.
Do not use the power or control cables to lift pump!
C-3.2) Thermal Protection:
The normally closed (N/C) over temperature 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 overtemperature condition
and/or motor starter coil to stop pump. In the event of an
overtemperature, the source of this condition should be
determined and rectified immediately. Thermal protection
shall not be used as a motor overload device. A separate
motor overload device must be provided in accordance
with NEC codes.
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.

C-3.3) Moisture Sensors: (Optional)
A normally open (N/O) detector is installed in the pump
seal chamber which will detect any moisture present. It is
recommended 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 tests prove
conclusive, the pump(s) should be pulled and the source
of the failure identified and repaired.
IF A MOISTURE
DETECT HAS OCCURRED SCHEDULE
MAINTENANCE AS SOON AS POSSIBLE.
C-3.4) Wire Size:
If additional cable is required consult a qualified electrician
for proper wire size. See Table on page 21 for further
electrical information.
SECTION D: SERVICE AND REPAIR
NOTE:
All item numbers in ( ) refer to Figures 10 & 11 for
2HP and to Figures 12 & 13 for 3.0, 5.0 & 7.5HP Pumps.
WARNING !
ELECTRICAL POWER TO THE PUMP MOTORS
MUST BE DISCONNECTED AND LOCKED OUT TO
PREVENT ANY DANGEROUS ELECTRICAL
HAZARDS OR PERSONNEL DANGER BEFORE ANY
SERVICE WORK IS DONE TO THE PUMP.
CAUTION !
OPERATING PUMP BUILDS UP HEAT AND
PRESSURE; ALLOW TIME FOR PUMP TO COOL TO
ROOM TEMPERATURE BEFORE HANDLING OR
SERVICING.
CAUTION !
ALWAYS WEAR EYE PROTECTION WHEN
WORKING ON PUMPS.
