use the accessory tool (Fig.3_point 5) or a screwdriver. You must survey the
operation and close the loading door as soon as the water comes out (however
it is recommended to t a check valve in the section of the suction pipe and to
use it to control the loading operation with the cap loose). Alternatively, in the
case where the suction pipe is intercepted by a closed valve, the loading op-
eration may be carried out in a similar way to the one described for installation
over head.
3 - COMMISSIONING
Maximum working pressure 8 bar.
The intake depth must not exceed 8m for e.sybox and 7 m for
e.sybox30/50.
3.1 - Electrical Connections
To improve immunity to the possible noise radiated towards other appli-
ances it is recommended to use a separate electrical duct to supply the
product.
Attention: always respect the safety regulations!
Electrical installation must be carried out by an expert, author-
ised electrician, who takes on all responsibility.
The system must be correctly and safely earthed as required by
the regulations in force.
The line voltage may change when the electropump is started.
The line voltage may undergo variations depending on other de-
vices connected to it and on the quality of the line.
The differential switch protecting the system must be correctly
sized and must be of the “Class A” type. The automatic differen-
tial switch must be marked with the following symbols:
The thermal magnetic circuit breaker must be correctly sized
(see Electrical Characteristics)
3.2 Conguration of the Integrated Inverter
The system is congured by the manufacturer to satisfy the majority of
installation cases, that is:
• operation at constant pressure;
• Set-Point (desired value of constant pressure): SP = 3.0 bar
• Reduction of pressure to restart: RP = 0.3 bar
• Anti-cycling function: Disabled
However, all these parameters and many others can be set by the user.
There are many other operating modes and accessory functions. Thanks
to the different possible settings and the availability of congurable input
and output channels, it is possible to adapt the inverter operation to the
requirements of various systems. See par. 5-6-7
For the denition of the parameters SP and RP, the pressure at
which the system starts has the value:
Pstart = SP – RP For example: 3.0 – 0.3 = 2.7 bar
in the default conguration
The system does not work if the utility is at a height higher than the equiv-
alent in metres of water column of the Pstart (consider 1 bar = 10 m water
column): for the default conguration, if the utility is at a height of at least
27m the system does not start.
