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
overload, the source of this condition
should be determined and corrected
immediately.
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.

Installation & Service
DO NOT ALLOW THE
PUMP TO CYCLE OR RUN IF AN
OVERLOAD CONDITION OCCURS.
WARNING
Pre-Operation
Check Voltage and Phase -
Compare the voltage and phase
information stamped on the
pump name plate.
Kickback should always be in a
counter-clockwise
direction
as
viewed from motor end or opposite
to impeller rotation. Impeller rotation
is counter-clockwise as viewed from
bottom of pump.
Name Plate -
Record the
information from the pump name
plate to drawing in front of
manual for future reference.
a) Inspect motor chamber for oil level
and contamination.
b) Inspect impeller and body for
excessive build-up or clogging.
c) Inspect motor, bearings and shaft
seal for wear or leakage.
No lubrication or maintenance is
required. Perform the following
checks when pump is removed from
operation
or
when
pump
performance deteriorates:
Maintenance
NOTE: Item numbers in ( ) refer to
Figure 5.
Servicing
After leak is repaired, dispose of old
oil properly, and refill with new oil.
Insulation 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.
Pump-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.
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".
Cooling Oil -
Anytime the pump is
removed from operation, the cooling
oil in the motor housing should be
checked visually for oil level and
contamination. To check oil, set unit
upright. Remove pipe plug (34) from
housing (3). With a flashlight, visually
inspect the oil in the housing (3) to
make sure it is clean and clear, light
amber in color and free from
suspended particles. Milky white oil
indicates the presence of water. Oil
level should be just above the motor
when pump is in vertical position.
Oil Testing
Ÿ
Drain oil into a clean, dry
container by placing pump on it’s
side, remove pipe plug (34), from
housing (3).
Ÿ
Check oil for contamination using
an oil tester with a range to 30
kilovolts breakdown.
Ÿ
If oil is found to be clean and
uncontaminated
(measuring
above 15 kV breakdown), refill the
housing.
Ÿ
If oil is found to be dirty or
contaminated (or measures below
15 kV breakdown), the pump
must be carefully inspected for
leaks at the shaft seal, cable
assembly, square ring and pipe
plug, before refilling with oil. To
locate the leak, perform a
pressure test.
