Electrical connection
Electrical connection - The appliance must be connected to the electrical mains according to
current legal regulations. Before making the connection, make sure of the following:
-
the voltage and frequency values of the power supply system match the values on the
"technical data" plate affixed on the appliance;
-
the limiting valve and the system are able to support the appliance's load (see the
"technical data" plate);
-
the power supply system has an adequate earth connection according to current legal

a omnipolar switch with minimum between-contacts aperture of the overvoltage category
III (4000 V), sized to the load and conforming to current legal regulations, is fitted
between the appliance and the mains in the direct connection to the mains;

Connection to the water mains
Connection to the water mains - The appliance must be fed with softened drinking water, with
hardness from 0.5°F to 3°F (it is obligatory to use a softener to reduce the formation of lime
inside the cooking chamber) and pressure in the range from 100 to 200 kPa (1.0 - 2.0 bar).
Connection to the water mains should be made through the threaded 3/4" solenoid-valve on the
rear (on the bottom) of the appliance, fitting in between a mechanical filter and an on/off tap
(before you connect the filter, allow a certain quantity of water to flow out in order to drain any
waste from the pipe).

Connecting the power cable - To access the terminal board, just remove the appliance's rear side-
panel. Loosen the cable gripper and allow the cable to pass through it. Arrange the conductors
so that the earth conductor is the last to detach from its terminal if the cable goes into a state of
faulty traction. Connect the phase
