It is advisable to install a water softener (1) for the water connection of the machine (Pic.17.1).
Attention. Before connecting the water softener to the machine, perform a rinsing cycle and
wait until the water is clear. Only after this you can connect the water softener to the machine.
Attention. The manometer “PUMP” shows the inlet pressure (the hydraulic mains pressure).
Therefore, even with the pump out of function, the manometer will never show “0” value. When the
pump is off, the pressure does not have to exceed 5 bars. The hydraulic mains pressure we recom-
mend is between 2-3 bars. If you register a higher or lower inlet pressure, please contact a specialist
to adjust the pressure. Anyway, the inlet pressure must not exceed 5 bars to avoid damages.
If the pressure of the mains is above 0.5 Mpa (5 bar), it is recommended to install a balanced pres-
sure reducing valve for high pressure (a device in which any increase in the mains pressure does not
affect the output pressure).
The water draining tube (2) must not bend to avoid water returns to the machine (Pic.17.2).
To complete the installation of the machine and assemble the cup warmer rail proceed as indi-
cated below. Follow the assembling instructions carefully. In case of maintenance / opening the
machine body, act the other way round.
