3.8 Power supply cable connection
Remove the back and left side of the appliance to access the power supply terminal board.
Loosen the cable retainer at the rear (bottom) of the appliance (see Fig.1) and run the cable
through it until reaching the terminal board. Prepare conductors for connection with the terminal
board so that the earth conductor is the last to be extracted from its terminal in the event the
cable should be abnormally pulled. Connect the 3 phase conductors (L1, L2, L3) of the cable to
the terminals marked with "1"(brown conductor) "2"(black conductor) and "3"(grey conductor)
of the terminal board, the neutral conductor (blue) to the terminal marked with "4" or "5" and
the earth conductor (yellow/green) to the terminal marked with the symbol (see diagram also
available by the terminal board):
Tighten the cable retainer on the rear of the appliance; fit the left side and back on again. The
cable must be as per specifications in the "Technical features" table (paragraph 2.2). The
appliance must be connected to an equipotential system the effectiveness of which must be
suitably assessed according to applicable regulations.
This connection must be performed between different appliances through the suitable terminal
which is marked with the symbol . The equipotential conductor must have minimum section
2.5mm². The equipotential terminal is at the rear of the appliance.
3.9 Connection to the water mains
The appliance must be supplied with softened drinking water, with hardness between 0.5°F and
5°F. and maximum temperature 30°C. It is obligatory to use a softener to reduce the formation
of limescale inside the cooking chamber. The water pressure must be between 100 and 200 kPa
(1.0 -2.0 bar). If the mains pressure exceeds 2.0 bar, install a pressure reducer upstream of the
appliance. If the value is lower than 1.0 bar use a pump to raise the pressure. The appliance is
equipped with flexible hose (1.5 metres) with threaded ¾" female fittings and relevant gaskets.
The old joints must not be used. Connection to the water mains must be performed through the
¾" threaded solenoid valve located at the rear (bottom) of the appliance (see Fig.1), interposing a
mechanical filter and a stopcock (before connecting the filter drain off a certain amount of water
to flush the pipe from any dirt).
Warning
Any damage caused by limescale or other chemicals contained in the water are not covered by
warranty.
3.10 Water drain
A drain pipe comes out of the rear of the appliance (see Fig.1) to drain the cooking chamber.
This pipe must be connected to piping with 30 mm inner diameter (DN 30) resistant to steam
temperature (90°C-100°C).
To avoid choking the pipe should be stiff and there should be no "elbows" along the drain path.
The pipe must also maintain constant slope (min. 5%) along its entire length (the length
considered is that of the appliance's drain pipe at the drain point and must not exceed 2 metres).
The drain piping must be conveyed into an open floor drain (Fig.2); otherwise, there must be at
least 30 cm height difference between the drain pipe of the appliance and the drain point in order
to assure regular water drainage.
Furthermore, the minimum "air gap" must be 25 mm (distance between the drain pipe from the
appliance and the cup of the drain duct pipe).
