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 flow-rate no lower
than the rated flow of the fill solenoid valve, the connection is G3/4M
(see par. “11.2 Technical specifications”);
•
hardness no greater than 40 °f (equal to 400 ppm of CaCO
3
),
conductivity: 75 to 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, affecting 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.
