Calcification protection
Limescale deposits from the water increase significantly at higher temperatures (>55°C). Set
the temperature as low as possible for this reason.
Observe hygiene regulations!
In order to ensure the longest possible service life of the plate heat exchanger, the manufac-
turer recommends using water softeners if the water hardness level is > 8.5°dH.
