strict accordance with national and
local safety regulations.
This machine conforms to IEC 61770
and EN 61770.
The water quality must conform to
the requirements for drinking water
in the country the machine is being
installed in.
– All items used for connecting the
machine to the mains water supply
must comply with the current national
and local safety regulations in the
country in which the machine is
being installed.

The flow pressure needs to be at
least 10
5
Pascal (1 bar). There is a
minimum flow pressure of 10
5
Pascal
if 5 litres of water flow into a suitable
container in 15 seconds.
–
The static water pressure must not
exceed 10
6
Pascal (10 bar). If it is
higher than this a pressure reducing
valve must be fitted.

The stainless steel hose is 1.5 m
long. The hose may not be
lengthened as too much water would
then remain in the hose, adversely
affecting the quality of the coffee.
–
A stopcock must be provided
between the stainless steel hose and
the household water supply to
ensure that the water supply can be
disconnected if necessary.
The stopcock should be easily
accessible after the machine has
been built in.
