5. CONTROL PANEL
The green light lit up indicates that the
device is energized (fig.1/a).
The yellow light lit up indicates that the
pump is running (fig.1/b).
The red light lit up indicates the
presence of an anomaly (fig.1/c).
Reset button to push in case of
anomaly (fig.1/d).

6. INSTALLATION - PLACEMENT
Install the device to ease the inspection, maintenance, and
assistance. Install the device in a well-ventilated room for
proper pump cooling.
The device may be installed internally or externally if protected
from direct sunlight, rain, and snow.
7. INSTALLATION - ASSEMBLING
The device may be installed directly on the pump or between
the pump and the first tap (fig.2).
Respect the maximum height indicated between the device and
the highest tap (fig.2/a – fig.3).
Install the device strictly with the flow arrows directed upwards
and in a position that facilitates control panel visibility and
accessibility (fig.2/b).
No tap can be installed between the pump and the device
(fig.2/c). It is recommended to apply a relief valve at the exit
of the device to test the pump's and the device's functioning,
excluding the hydraulic system through the valve and verifying
the effective pump prevalence with the pressure gauge.
If the pump is placed above the head, always provide a non-
return valve at the entrance of the suction line.

8. INSTALLATION – RESTART VALUE / SYSTEM HEIGHT
The maximum pressure generated by the pump must be at least
1 bar above the restart pressure of the device. In particular, the
pump's effective pressure and the height of the water column
of the system that weighs on the device must be checked with
the start-up pressure of the device itself. (fig.3). The pump stops
if the pressure generated fails to reach the values indicated in
the chart.
The pump starts without restarting if the height of the water
column exceeds the values indicated in the chart.
The restart pressure value is indicated on the side or the
backside of the device.

9. ELECTRICAL WIRING
Electrical shock – Risk of death or serious
personal injuries.
Turn off the power before starting to work on the
device. Check that the power supply cannot be
restored accidentally.
Electrical shock – Risk of death or serious
personal injuries.
Connect the wires to the protective conductor of the
earthing system and protect it from indirect contacts in
compliance with relative local regulations.
Power cables without plugs must be connected to a
switch in compliance with the relative local regulation.
- The system must be equipped with a residual current device
(RCD) with a trip current lower than 30 mA. The device must
be connected to an external network switch with a distance of
at least 3 mm at all poles.
- Electrical wiring must be performed by qualified personnel in
compliance with relative local regulations.
- The device may be powered by a generator or by an
alternative energy supply if power supply requirements have
been satisfied.
- Connect the device to a power source through the supplied
cable and plug.
- Connect the products without the supplied cable by following
the instructions listed below:
1. Remove the cover from the forward part of the device.
2. Carry out the electrical wiring according to the electrical
diagram (fig. 4/a).
3. Fix the cover with all the screws and ensure to close the
cable gland rings well to maintain the IP65 protection class.
