c.
Check water source. Never operate the pump if water has presence of excess sand or any solid
particles.
d.
Check motor insulation using insulation tester. Never activate the motor if insulation reading
is less than 100 mega ohms. Please check IOM manual of submersible motor for details.
e.
Check power voltage. Never operate motor if voltage is not within the normal range. Please
refer Section VII. #5.a for reference.
e.
Make sure rotation of electric motor is correct prior for start-up to avoid producing strong

a.
Close the isolation valve in discharge pipe.
b.
Start the driver.
c.
Slowly open the isolation valve in discharge pipe.
d.
Do not operate the pump exceeding to its rated working pressure.
e.
Use calibrated tester or current meter instrument to check if actual current of motor is within
the normal range.
f.
Observe the pump & discharge pipe. If excess vibration and disturbing noise are observe,
immediately shut down the motor and inspect the pump and main riser column pipe.
f.
Adjust all necessary protective electrical components in control panel for motor protection.
g.
Do not operate electric motors if actual voltage fluctuates. Please refer Section VII. #5.a for
