The appliance must be connected to a main switch that cuts off all the power supply poles.
When the switch is in off position, the distance separating each contact must respect the
indications in table 0tris.

3.2 Configuration of the Integrated Inverter

The system is configured by the manufacturer to satisfy most installation cases operating
at constant pressure. The main parameters set in the factory are:
• Set-Point (desired value of constant pressure); SP = 2.7 bar / 39 psi.
• Reduction of pressure to restart RP = 0.3 bar / 4.3 psi.
• Anti-cycling function: Disabled.
However, these parameters and others can be set by the user according to the system. See
par. 5-6-7 for the specifications.
For the definition of the parameters SP and RP, the pressure at which the
system starts has the value:
Pstart = SP – RP For example: 2.7 – 0.3 = 2.4 bar in the default configuration
The system does not work if the utility is at a height higher than the equivalent in metres of
water column of the Pstart (consider 1 bar = 10 m water column): for the default configura-
tion, if the utility is at a height of at least 27m the system does not start.
3.3 - Priming
The priming of a pump is the phase during which the machine attempts to fill the body and
the suction pipe with water. If the operation is successful the machine can work regularly.
