in long and winding pipe runs.
Piping should never rest its weight on the pump.
Sealing adhesive should not be used to seal pump
connections. Use sealing tape for this purpose.

3.4. Electrical connection.

CONNECTING THE PUMP TO THE MAINS (Fig.1)
The electrical installation shall have a multiple
separation system with contact opening
≥3mm.
The protection of the system shall be based
on a differential switch (Iŋ=30 mA).
The electrical connection shall be made by
connecting the pump socket directly to a domestic
power socket duly protected according to the
regulations in force in each country. The electrical
connections must be made according to IEC-60364
(electrical installations in buildings) or according to
the regulations in force in the country of destination.
Single-phase motors have built-in thermal
protection.

3.5. Checks prior to initial start-up

Check that the mains voltage and frequency
correspond to those indicated on the
nameplate.
Make sure that the pump shaft rotates freely.
Fill the pump body completely with water
through the filler plug. If you have installed a
foot valve, fill the suction pipe.
Make sure that there are no leaking seals or
fittings.
THE PUMP MUST NEVER RUN WITHOUT
WATER.
The electrical installation must be effectively
grounded and must comply with current
national regulations.

4. STARTING

4.1. Start-up and operation

Open all shut-off valves in the system, both suction
and discharge.
Switch on the power supply. The LINE voltage
indicator lights up.
The pump-motor unit starts automatically. During
operation of the pump, the (RUN) indicator lights up.
During this operation, keep a water outlet tap open
to purge the air from the installation. Once the
installation has been purged, close the tap and the
unit will stop after ± 10 seconds. Only the voltage
indicator (LINE) will be illuminated.
If the pump is not properly primed or there is no water
to feed it, the pump will stop after 10 seconds and
the LED (FAULT) will light up. To complete the
priming of the pump, press the (+) and (-) keys
simultaneously, thus restarting the circuit and the 10-
second timer.
With a water consumption of more than 2 l/min the
pump is always running, below this consumption the
control flashes the RUN LED to indicate that we are
below the minimum flow rate and after about 10
seconds the pump stops.
If the motor does not work or does not extract water,
try to find out the anomaly through the list of the most
common possible faults and their possible solutions
that we provide on the following pages.

4.2. Set point pressure adjustment.

To raise or lower the setpoint pressure, the pump must be
running and the RUN LED must be permanently lit. By
pressing and holding one of the two control buttons (+) or
(-) the set pressure is varied.
The start pressure is set to 0.5 bar below the set pressure.

Fault: Error LED.
Run: Always on when the engine is running. If it flashes,
it indicates low or minimum flow.
Line: Mains voltage indicator.
+ - : Set pressure adjustments.
