4. STARTING

If there is a line valve, open it completely.
Connect the power supply switch. Water will never
flow at the end of the line immediately; if the path is
considerable, wait a few minutes. The voltage
indicator will light up (LINE).
The unit then starts automatically. While the pump
is working, the function indicator will be lit (RUN).
During this operation, keep a water outlet tap open
to purge any air existing in the installation. Once the
installation is purged, close the tap; the group will
stop after 10 seconds. Only the voltage indicator
(LINE) will remain lit.
If the pump is not properly primed or no water
supply is available at start-up, the FAULT LED
indicator will light up after 10 seconds. To complete
pump priming, press the (+) and (-) buttons
simultaneously; this will reinitiate the circuit and the
10-second timing.
The pump continues working with a water supply of
over 2 l/minute; below this level, the control makes
the RUN LED blink intermittently to indicate that
water flow is below minimum and the pump stops
after about 10 seconds.
Just before the circuit stops the pump, the electrical
control increases the motor revolutions slightly to
raise the default pressure a bit and stay paused
longer.
If the motor does not start or no water flows at the
end of the line, try to find the anomaly using the
troubleshooting guide in point 8.

4.1. Default pressure adjustment

To raise or lower default pressure, the pump must
be functioning and the RUN LED must be lit
constantly. Change the
pressing the (+) or (-) control button. Start-up
pressure is adjusted 0.5 bar below default pressure.
(Fig.9)
Comments: Default pressure must be 0.5 bar above
the highest outlet of the installation. Default
pressure must be adjusted from 1.5 bars to 4.5
bars. (Fig.4)
4.2. Faiure detection
If the electrical circuit detects lack of water, the
pump will stop and the Alarm LED will blink. The
circuit will make 4 attempts; if pressure cannot be
re-established because of lack of water, the circuit
will stay in FAULT indefinitely, until manual
reactivation.
While the pump is stopped in FAULT mode, waiting
for re-attempts, the Alarm LED will blink. After the 4
attempts without success, the Alarm LED will
remain lit without blinking.
The Fig.8 shows the times that pass between the
different attempts, if none of them is successful.

5. MAINTENANCE

These submersible pumps do not require maintenance.
During frosty periods, remember to drain the
line and any water from inside the pump and
the kit.
If the pump will be out of service for extended
periods, it should be removed from the well
and stored in a dry, well-ventilated location.
Warning: In the event of faults or damage occurring
to the pump, repairs should only be carried out by
an authorised service agent.
