WATER CONNECTIONS
Carefully comply with any national or regional
regulations in force.
Water
installation must have the following
characteristics:
Temperature
:
55°C (P440-ek)
Dynamic Pressure
:
-
2 ÷ 4 bar (200÷400 kPa);
For machines with steam condenser P440-CV:
Temperature
:
10÷12 °C
.
ATTENTION!: do NOT connect to softened
water.
WARNING!
If the water pressure is higher than 4 bar, fit the
pressure reducer “A” supplied into the solenoid
valve as shown in the drawing.
If the dynamic pressure is lower than specified
on the data plate of the machine, it is advisable
to install a Booster Pump.
Hardness:
between
7,2 and 12,5 °French
.
If the hardness values are higher than
those mentioned above, it is advisable to install
a water-softener.
