•
this contains the same substances dissolved in the supply water,
however in larger quantities;
•
it may reach a temperature of 100 °C;
•
it is not toxic and can be drained into the sewerage system, category
3, EN 1717.

4.3 Supply water
Only use mains drinking water with:
•
pressure between 0.1 and 0.8 MPa (1 and 8 bars), temperature between
1 and 40 °C and an instant fl ow-rate no lower than the rated fl ow of the
fi ll solenoid valve, the connection is G 3/4’’ M;
•
hardness no greater than 400 ppm of CaCO3 (40 °fH), conductivity
range: 75-1250 μS/cm;
•
no organic compounds.

There is not reliable relationship between hardness and conductivity of
the water.
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.
