The borewell should fully be developed and flushed free of cutting and sand.
Ÿ
Determine the maximum depth of well and the draw down level at max pump capacity. Pump setting depth should be
atleast one meter below the max draw down level.
Ÿ
Ensure a minimum velocity of 0.2 m/s part of the motor for proper cooling.
Ÿ
The motor should be filled with pure drinking water free of any silt or suspended particles. Replace the water filling drain
plugs without fail.
