Installation
65
Before attaching the inlet hoses to the machine, the filters and seals
included in the accessory pack must be inserted.
Hoses must be replaced with hoses tested for a burst pressure of at
least 7000 kPa (70 bar) and for water temperatures of a minimum of
90 °C. This also applies to the associated connection fittings. Miele
original spare parts fulfil these requirements.
The hot water supply must not exceed a maximum temperature of
70 °C.
Connection to the
cold water supply
- See the installation plan provided.
Use of non-return
valves
In Germany, the machine must be connected to the water supply us-
ing the non-return valve provided.
According to national regulations for drinking water quality, with ef-
fect from 21 March 2021, a non-return valve to prevent backsiphon-
ing must be installed between the stopcock and the water inlet hose
during commissioning on all machines in Germany. The non-return
valve prevents water from the water inlet hose from flowing back into
the on-site drinking water supply.
