Switching on the product

Danger!
Risk of scalding caused by hot water
During operation, the domestic hot water
temperature can reach 70 °C. As of a do-
mestic hot water temperature of 43 °C, there
is a risk of scalding.
▶
The installer must ensure they activate
the scald protection for limiting the do-
mestic hot water temperature in order to
prevent any risk of scalding, especially
when the product is used with a shower.
