The wiring diagram inside the terminal block will show you how to make correct connection.
Wrong connection will destroy the whole electronic circuit. Cable used for connection must be a
three-wired one with compulsory grounding end. It shall have the outer diameter at 6 mm min and 9
mm max. One of the leading end of the cable must be lower than the position of the fixing screws
while the cable being connected to the power as shown in the fig.
The four screws on the panel board and the two nuts for fixing cable must be well fastened to avoid
water entering into the control box and damaging the electronic circuit.

It is advisable to
connect the unit outlet
to the system by means
of a flexible hose.
If the column of water between
the pump and the highest tap
exceeds 15 mts, the unit cannot
be installed directly on the pump,
but it has to be raised until the
column of water between the unit
and the highest tap does not
exceed 15 mts.
I.E. If column of water is 20 mts.
from the pump, the unit musb be
places 5 mts higher than the
pump.
The unit is equipped with a
check valve to prevent the
pipeline from losing pressure.
No taps can be installed
between the pump and
the unit.
Pump´s pressure
The unit is pre-set by the
manufacturer at a restarting
pressure of 1.5 bar.
The pressure produced by the
pump must be normally 0.8 bar
higher than the pre-set pressure.
Before starting the unit check
suction and ensure that the
pump is primed.
It´s imperative to install
the unit with the arrows
in the upward position.
The unit can be installed
directly on the pump, or
between the pump
and the first tap.
15 mts max
