Protection against dry running
The standard electric panel is ready for connection of a common float switch applicable for open tanks or a
minimum pressure switch on the suction side (recommended value 0.2÷0.4 bar). When the minimum pressure
conditions are restored, the pumps start up automatically. If protection against dry running is considered
superfluous, do not remove the jumper on the terminal in electrical panel. The correct terminal numbers are
specified in wiring terminal that is found inside the panels.
Factory setting: the electric pump e-SM drive comes from the factory with the software protection enabled.
No dry running control: the booster unit comes from factory with jumper already installed, which disabled the
control.
With the optional electronic level kit, control by electric probes is possible.
Put the three electric probes that are supplied with the kit inside the storage tank and connect them to the
terminal in the electric panel.
The correct terminal numbers are specified in the wiring diagram inside the panel:
Probe Max (A) determines the unit activation level during the filling of storage tank.
Probe Min (B) determines the unit deactivation level.
Probe (C) must be put at a lower level than that of the bottom probe (B).

Outdoor installation

When the unit is installed outdoors a suitable cover must be provided. See Figure 8.
The cover must be sized to ensure that the booster unit is not exposed to snow, rain, or direct sunlight.
