Electrical connection - The appliance must be connected to the electrical mains according to Electrical connection Electrical connection Electrical connection
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 the power supply system has an adequate earth connection according to current legal
the power supply system has an adequate earth connection according to current legal the power supply system has an adequate earth connection according to current legal
regulations; regulations; regulations; regulations;
- 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;
- the omnipolar switch used for connection is easy to reach when the appliance is installed;
- the yellow/green earth wire is not interrupted by the switch; the the the yellow/green earth wire is not interrupted by the switch; yellow/green earth wire is not interrupted by the switch; yellow/green earth wire is not interrupted by the switch;
- the power supply, when the appliance is operating, must not deviate from the rated
voltage value by ±10%;
- make sure that after inserting the power supply cord into the terminal block it does not
come into contact with any of the cooking range's hot parts.
- if the supply cable is damaged then it must be replaced by the manufacturer or by your if the supply cable is damaged then it must be replaced by the manufacturer or by your if the supply cable is damaged then it must be replaced by the manufacturer or by your if the supply cable is damaged then it must be replaced by the manufacturer or by your

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- Connecting the power cable Connecting the power cable Connecting the power cable
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
connecting the neutral neutral conductor to the terminal marked "N" neutral neutral
terminal marked with the symbol
(this electrical connection lay-out is located near the power supply terminal board ). Tighten the
cable gripper and re-fit the rear side-panel of the appliance.
The appliance must be connected to an equipotential system
checked according to current legal regulations.
This connection must be made between different appliances by using the appropriate terminal
marked with the symbol
2
mm The equipotential terminal is at the rear of the appliance.
