10. MAINTENANCE AND REPAIR
Often control the plant trying to eliminate the disturbing causes
such as sand, lime, etc. Keep efficient the parts exposed
to damages (valves, filters, detectors and protections). For
interventions always call qualified technicians.
In case of long rests provide to often start the electropump.
Any replacement of the feeding cable as well as all other
maintenance operations must be performed only by the
assistance centre.
11. DEMOLITION
When demolishing the electropumps, follow strictly the
regulations in force in your country.
The user is responsible for disposing the equipment by
delivering it to a collecting point for recycling and disposal
of electrical equipment.
For further information about the collecting points of
equipment, contact your local authority for waste disposal,
or the shop where you purchased your product.

9. USE AND RUNNING
• With discharge gate (5) completely opened no more air
should leak from the piping. Close almost completely
the gate and start the electropump waiting for the exit
of clean water without air bubbles.
Close the gate and control on the pressure-gauge (4)
that the maximum pressure data corresponds to the
one shown in our catalogue, if not, reverse the sense
of rotation of the motor only for three phase motors.
• Gradually open the gate and run the pump until clean
water is coming out.
If the well has correctly been built and previously bled,
clean water will come out in 15 minutes.
• During the previous instructions, control voltage and
current; admitted intermittent rush of current of ±5%
for voltage and current referred to plate data.
ATTENTION
NEVER RUN
THE PUMP DRY.
NEVER LET THE PUMP WORK WITH CLOSED
GATE FOR MORE THAN 2 MINUTES.
NEVER LET THE PUMP RUN IN THE
OPPOSITE DIRECTION FOR MORE THAN 30
SECONDS.
13. TROUBLESHOOTING
FAULT
DISPLAYING
CAUSE SOLUTION
THE PUMP DOES NOT WORK
THE ENGINE DOES NOT RUN
Lack of electricity Check the counter of the power line
Plug not inserted Check the electrical connection to the line
Incorrect electrical connection
Automatic breaker tripped or fuses burnt
Check terminal board and control panel - Reset the
circuit breaker or replace fuses and check the cause
THE PUMP DOES NOT WORK
THE ENGINE RUNS
Suction hole/filter obstructed Clean filter/hole
Pressure too low Choke the discharge gate
THE PUMP WORKS WITH REDUCED
CAPACITY
Plant too small Review the plant
Dirty plant Clean pipes, valves, filters
Water level too low Turn off the pump
Incorrect sense of rotation (three phase only) Invert two phases between them
Incorrect power supply voltage Feed the pump with data voltage
Pressure too high Review the plant
THE PUMP STOPS AFTER SHORT
OPERATIONS INTERVENTION OF THERMAL
PROTECTION
Internal fault Contact the nearest dealer
THE PUMP VIBRATES OR IS VERY NOISY
DURING ITS RUNNING
Capacity too high Reduce the capacity
Irregular pipes Fix them in a better way
