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
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 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
technical support or by a qualified person to avoid any risk.
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).
Connection of power cable - To access the power supply terminal board just remove the
side/rear panel of the appliance. Loosen the ring nut of the cable gland at the rear of the
appliance and run the cable through it until reaching the terminal board. 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 conductor to the terminal marked with the
letter "L", the neutral conductor to the terminal marked with the letter "N" and the earth
conductor to the terminal marked with the symbol
. Tighten the ring-nut of the cable gripper
and close the terminal board cover. The appliance must be connected to an equipotential
system whose efficiency must first be checked according to current legal regulations. This
connection must be made between different appliances by using the appropriate terminal
marked with the symbol . The equipotential conductor must have a minimum diameter of 2,5
mm
2
The equipotential terminal is at the rear of the appliance.
Safety thermal breaker - The appliance has safety thermal breaker. It protects against excessive
dangerous over-temperatures which could be accidentally generated inside the appliance. If the
device is tripped, it interrupts electrical power to the appliance and thus prevents it from
operating.
