SERVICE MANUAL
EVO FRONT LOADING DISHWASHER
suitable omnipolar cut-off Circuit Breaker with a minimum contact separation of 3 mm must be installed.
This device should be used to disconnect the appliance during installation, repair, cleaning and
maintenance work. It is recommended that it has lockout-tagout capabilities. The manufacturer will not be
held liable for damage originated by failure to observe this requirement.
• A suitable safety switch / Residual current device must be installed near the appliance between the power
supply and the appliance. The manufacturer will not be held liable for damage originated by failure to
observe this requirement.
• If any faults are observed during the installation of the equipment, the supplier should be notified
immediately.
To access the connection strip, release the left side panel, pass the cable sleeve through the stuffing box on the
lower exterior base and connect as shown on the strip.
.
VERY IMPORTANT: Before installing the left side panel, attach the electrical supply hose securely to
the stuffing box.
When several appliances are installed in series, they should be earthed to each other using the point
assigned for this purpose, located in the oven base, at the back. The connection is represented by the
symbol.
8.2. HYDRAULIC CONNECTION
Before connecting the machine to the mains water supply, the
water must be tested and should comply with the following
requirements:
If the water quality does not meet the specified requirements, contact a professional able to advise on the water
treatment systems necessary to make the water suitable and to obtain a satisfactory process.
If the water hardness is higher than that indicated, a descaler should be installed to prevent the build-up of lime on
the machine and to permit optimum cleaning and drying. It is also possible to install a SOFT model with built-in
descaler (n this case if the water hardness is higher than 45 ºfH / 31.5 ºeH / 25.2 ºdH, it will still be necessary to
install an external descaler).
In addition to water quality, the pressure of the mains water supply must be considered. This is important to ensure
the unit operates correctly. The dynamic pressure of the water inlet must be within the values indicated in the
following table.
