Maximal allowed content of individual substances in heated water and their influence on the
heat exchanger are shown in the table below. The heated water which includes any
substance in a concentration which causes corrosion (influence "-") in the heating system is
forbidden. The heating water which contains two or more substances in a concentration,
which may cause corrosion (influence "0") in the heating system is also forbidden.

Table: Influence of various aggressive substances in heating water onto the durability of hot
sanitary water tank (
+ = no influence, 0 = danger of corrosion, - = corrosion
– use forbidden)
.
WARNING
The heating system must be filled with water of a hardness between 5 °dH and
10 °dH . Device defects due to unsuitable heating water hardness are not
covered by warranty.
WARNING
Quality of potable water must comply with Potable Water Regulation (Official
Gazette of the Republic of Slovenia, no. 19/04, 35/04, 26/06, 92/06, 25/09).
This regulation complies with the European Council Directive 98/83/EC.
WARNING
For proper operation of active anti-corrosion protection, the hot sanitary water
tank (boiler) must be filled with water, the conductivity of which is at least
200
µS.
