2.1 Supply water
Only use mains water with:
•
pressure between 0.1 and 0.8 MPa (14.5 and 116 PSI), temperature
between 1 and 40 °C (33.8 and104 °F) and an instant fl ow-rate no lower
than the rated fl ow of the fi ll solenoid valve, the connection is G3/4M
(see par. "11.2 Technical specifi cations");
•
range hardness 10 to 40 °F (equal to 400 ppm of CaCO
75 to 1250 μS/cm;
•
no organic compounds.

There is not reliable relationship between hardness and conductivity of
the water
Important:
Important:
•
do not treat the water with softeners, this may cause the entrainment
of foam, aff ecting the operation of the unit;
•
do not add disinfectants or anticorrosive compounds to the water, as
these are potential irritants;
•
the use of well water, industrial water or water from cooling circuits
and, in general, any potentially chemically or bacteriologically
contaminated water is not recommended.
2.2 Drain water
•
this contains the same substances dissolved in the supply water,
however in larger quantities;
•
it may reach a temperature of 100 °C (212 °F);
•
it is not toxic and can be drained into the sewerage system.
