Submersible Pump Installation Check List

❑F. Check insulation resistance as pump/motor assembly is lowered into the well. Resistance may drop gradually as more cable enters the water, but any sudden drop indicates possible cable, splice or motor lead damage; see page 44.

9.After Installation

❑A. Check all electrical and water line connections and parts before starting the pump.

❑B. Start the pump and check motor amps and pump delivery. If normal, continue to run the pump until delivery is clear. If three-phase pump delivery is low, it may be running backward. Rotation may be reversed (with power off) by interchanging any two motor lead connections to the power supply.

❑C. Check three-phase motors for current balance within 5% of average, using motor manufacturer instructions. Imbalance over 5% will cause higher motor temperatures and may cause overload trip, vibration, and reduced life.

❑D. Verify that starting, running and stopping cause no signifi cant vibration or hydraulic shocks.

❑E. After at least 15 minutes running time, verify that pump output, electrical input, pumping level, and other characteristics are stable and as specifi ed.
