OPERATION
7
Plug the pump cable into a
grounded
receptacle.
It is
strongly
recommended that a Ground Fault In
terrupter (GFI) type receptacle (or equivalent) be
used (see Figure 2).
Operational Checks
Check the pump for proper operation when it is first
started and periodically thereafter to identify minor
problems.
Check the pump for unusual noises or excessive
vibration while it is operating. If noise or vibration is
excessive, stop the pump and refer to the
troubleshooting chart for possible causes.
Check the pump strainer screen for clogging
caused by stones, sticks, or other debris. Clean
the strainer screen when required. In some cases,
stopping the pump momentarily may back flush
the strainer screen, purging most of the debris
from it. If this fails to clean the screen, unplug the
pump, remove it from the sump, and remove the
debris manually.
Never
introduce air or steam pressure into the
pump casing or piping to remove a blockage. This
could result in personal injury or damage to the
equipment.
Each of these pumps has a built‐in thermal protec
tion switch in the motor. The pump will stop if over
heating occurs. The pump will restart automatically
after it has cooled down.
The integral thermal overload switch
will
shut off the motor if the temperature
rises above design limits. When the
pump cools and the temperature falls
below these limits, the motor will restart
automatically. To avoid the hazards of
an unexpected motor start‐up, unplug
the power cable from the receptacle be
fore attempting to handle the pump;
otherwise, serious personal injury
could result.
STOPPING
To stop the pump when in manual mode, simply
unplug it from the receptacle. After stopping the
pump, be sure to perform all required maintenance
and preservation procedures.
This pump is equipped with automatic
thermal overload protection which will stop
the pump if overheating occurs. Unplug
the pump and allow it to cool before at
tempting to service the pump.
When operated in the automatic mode, the pump
will stop and start as the liquid level rises and falls.
For service or extended stopping, unplug the
pump from the receptacle.
Storage and Cold Weather Preservation
After stopping the pump, use the rope or chain at
tached to the lifting handle on the pump to remove
the pump from the sump.
Do not
lift the unit by the
power cable or the discharge piping. Customer in
stalled equipment such as rigid discharge piping
must
be removed before attempting to lift.
Do not attempt to lift the pump by the
power cable or piping. Attach proper
lifting equipment to the handle on the
pump.
Clean the strainer screen before storage. If the
application involves a lot of mud or sludge, remove
the strainer and clean the impeller before storage.
NOTE
The most common cause of failure to run is hard
ened mud or sludge in the impeller.
In freezing temperatures, the pump will not freeze
as long as it is submerged in liquid. If the pump
casing is not submerged, or if the liquid begins to
freeze, remove the pump from the sump and allow
