Hydraulic connection.

The new hoses supplied with the appliance should be used (do not reuse old hoses). Before connect-
ing the machine to the water supply, the water quality should be tested. Please refer to table 5.
If the water hardness is more than 10 ⁰fH (French degrees), a descaler must be installed. In addition
to water quality, the pressure of the mains water supply at the installation must be considered. This is
important to ensure the machine operates correctly. (See table 6)

PRES-
SURE
If the water pressure is higher than the recommended pressure, a pressure regulator must be
mounted at the output (see figure 2). If the mains water pressure is lower than the recommended
pressure, a pressure pump should be mounted at the mains water supply outlet (see figure 3).
