IMPORTANT
Provide the connections next to the machine on the left
or the right.
Define the precise dimensions taking the local
circumstances into account.

15.3 Water connection
The water-related safety should be as per DIN EN 61770. The machine can be connected to an inlet water
supply without an intermediate connection to other safety equipment.

Water hardness
We recommend a maximum hardness of 3 dH (3.8 e / 5.34 TH / 0.54 mmol/l) to
prevent scaling in the machine.
with UF Energy
:
With conductivity < 200 µS/cm (128 ppm TDS), a stainless-steel heat exchanger
is necessary.
