Electrical Connections
Power cable:
The power cable 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 electric codes. It is
recommended that a junction box, if
used, be mounted outside the sump
or be of at a minimum Nema 4
construction if located within the wet
well.
DO NOT USE THE POWER
CABLE TO LIFT PUMP.
Overload Protection:
Single Phase
- The stator 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.
Always rely upon a Certified
Electrician for installation.
IMPORTANT! -
The overload will then
automatically reset and start the
pump up after the motor cools to a
safe temperature. In the event of an
o
verload, the source of this condition
should be determined and corrected
immediately.
DO NOT ALLOW THE
PUMP TO CYCLE OR RUN IF AN
OVERLOAD CONDITION OCCURS.
WARNING
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.

Pre-Operation
1.
C
heck Voltage and Phase -
Compare the voltage and phase
information stamped on the
pump name plate.
2.
Check
Pump Rotation -
Improper
motor rotation can result in poor
pump performance and can
damage the motor and/or pump.
Check rotation on three phase
units by momentarily applying
power and observe the "kickback".
3.
N
ame Plate -
Record the
information from the pump name
plate to drawing in front of manual
for future reference.
4.
I
nsulation Test -
An insulation
(megger) test should be performed
on the motor. Before the pump is put
into service. The resistance values
(ohms) as well as the voltage (volts)
and current (amps) should be
recorded.
5.
P
ump-Down Test -
Be sure pump
has been properly wired, lowered
into the basin, sump or lift station,
check the system by filling with liquid
and allowing the pump to operate
through its pumping cycle. The time
needed to empty the system, or
pump-down time along with the
volume of water, should be recorded.
No lubrication or maintenance is
required. Perform the following
checks when pump is removed from
operation
or
when
pump
performance deteriorates:
Maintenance
a)
I
nspect motor chamber for oil
level and contamination.
b)
I
nspect impeller and body for
excessive build-up or clogging.
c) I
nspect motor, bearings and shaft
seal for wear or leakage.
