EBARA SB3 Use And Maintenance Instruction Manual page 7

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.
NEVER RUN
ATTENTION
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.

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.
12. TECHNICAL DOCUMENTATION ATTACHED
Installation diagram.
CAUSE
Lack of electricity
Plug not inserted
Incorrect electrical connection
Automatic breaker tripped or fuses burnt
Suction hole/filter obstructed
Pressure too low
Plant too small
Dirty plant
Water level too low
Incorrect sense of rotation (three phase only)
Incorrect power supply voltage
Pressure too high
Internal fault
Capacity too high
Irregular pipes
SOLUTION
Check the counter of the power line
Check the electrical connection to the line
Check terminal board and control panel - Reset the
circuit breaker or replace fuses and check the cause
Clean filter/hole
Choke the discharge gate
Review the plant
Clean pipes, valves, filters
Turn off the pump
Invert two phases between them
Feed the pump with data voltage
Review the plant
Contact the nearest dealer
Reduce the capacity
Fix them in a better way
