Water
installation must have the following
characteristics:
Temperature
:
10÷12 °C
Dynamic Pressure :
2 ÷ 4 bar (200 ÷ 400 kPa).
If the dynamic pressure is lower than
specified on the data plate of the machine, it is
advisable to install a Pump for pressure
increase.
If the dynamic pressure is higher than 4 bar, it is
advisable to install a pressure reduction.
Hardness:
between
7,2 and 12,5 °French
.
If the hardness values are higher than
those mentioned above, it is advisable to install
