The steamer requires a permanent connection to the water
supply by means of a 1/4 ”connector on the back of the
same. The steamer is equipped with a
flow reducer
and a
Y filter
with a 300 micron filter mesh on the water loading
circuit (both are located inside the steamer and therefore are
not visible from the outside).
To avoid corrosion and limescale phenomena, the
incoming water must have the following chemical/physical
characteristics:
• have a maximum temperature of
30°C
;
• be
drinkable
;
• have a pressure value between 150 and 600 kPa (200 kPa
recommended). If the inlet water pressure is lower than
the specified minimum value (150 kPa), a pump must be
installed (minimum flow rate: 300 l/h);
• have 1000 μS/cm maximum water conductivity;
• Free chlorine ≤ 0.1 ppm
• Chloramines ≤ 0.1 ppm (mg / L)
• TDS ≤ 125 ppm
• Silica ≤ 12 ppm
• pH 7 ÷ 8.5
• Total hardness (TH) ≤ 6 °dH
• Chlorides ≤ 25 ppm
• Alkalinity ≤ 150 mg/L as CaCO3
If the water values differ from those listed above, it is
necessary to adequately treat the incoming water to bring
the values within the limits indicated for each circuit.
It is advisable to install an
shut-off cock (not supplied)
between the water mains and the steamer.
For the connection to the water mains, a new hose (not
supplied) must be used; the hoses already used must not
be reused.
