Hydraulic connection.

The new hoses supplied with the appliance should be used (do not reuse old hoses). Before connecting the
machine to the water supply, the water quality should be tested. Please refer to table 6.
If the water hardness is more than 10 ⁰fH (French degrees), a descaler must be installed. In addition to wa-
ter 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)

SURE
If the water pressure is higher than the recommended pressure, a pressure regulator must be mounted at
the output (see figure 4). 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 5). It is not necessary to install a
pressure pump in the model (TECH-H500 HP W B).
