Table: Influence of various aggressive substances in heating water on the device. ( + = no
influence, 0 = danger of corrosion, - = corrosion - use not permitted).
CAUTION
The heating system has to be filled with water with the hardness between 5 °dH and
10 °dH. Malfunctions of the device because of water hardness are not covered by the
