INSTRUCTION MANUAL (Translation from the original Spanish)
Considerations:
The set pressure must be 10 m. (1 bar.) above the highest
tap of the installation (H.max).
Pressure limited between 1.5 and 2.5 bars.
4.3. Fault detection / Automatic restarting
In the event that the electronic circuit detects a lack
of water, it will stop the pump and the alarm LED will
flash. The circuit will make 4 attempts to connect and
if no attempt is successful in re-establishing the
pressure due to lack of water, the circuit will remain
in fault mode indefinitely until it is manually
reactivated.
While the pump is stopped in fault mode, waiting for
a retry, the alarm LED will be flashing and if 4
unsuccessful retries have been made, the alarm
LED will always remain active.
The following graph illustrates the time that elapses
between the different retries in the event of not
succeeding in any of them.
Pressing the (+) and (-) buttons simultaneously
resets the circuit.

6. LEVEL PROBE
It is possible to install an external level probe for the
suction tank. The probe must be of the float type.
See connection diagram fig. 1.
Never open
disconnected the power supply for at least 5
minutes.
7. MAINTENANCE
Our pumps are maintenance-free.
In times of frost, be careful to empty the pipes.
If the pump is not to be used for a long period
of time, it is recommended to dismantle it and
store it in a dry and ventilated place.
ATTENTION: In the event of faults or damage
occurring to the pump, both the replacement
of the electric cable and the manipulation of
the equipment should only be carried out by
an authorised service agent.
