Warning
Switch OFF the power before working on electrical lines
Caution
Do not use this pump for pumping liquid exceeding 33
0
C as this may lead to
product failure
Warning
Do not switch ON the pump if there is any human contact with the pumped
medium. If any electrical leakage occurs, this could be fatal
Caution
The Openwell Submersibles has water lubricated journal and thrust bearings
and therefore shall not be run dry. Starting of the Openwell Submersibles
without water must be strictly avoided as it will cause damage to the
bearings. Fill with pure drinking water
Note
During monsoons, the pump will run with higher flooded suction resulting in
the pump running with higher discharge. This results in increase in the current
drawn being higher than that specified on the name plate. Fit a gate valve in
the delivery line to throttle the discharge till the current is lower than that
specified on the name plate
Caution
Ensure proper direction of rotation of the pump on powering up.
Operation Precautions
Note
Check the bottom of the well. In case there is mud accumulated at the well
bottom, de-silt the well
Note
Periodically de-silt the bottom of the well so that the Openwell Submersibles
rests on the rocky bottom
