To reach the power terminal board remove the left side of the appliance. Loosen the cable-
clamp on the back (at the bottom) of the appliance (see Fig. 1) and pass the cable through up
to near to the terminal board. Locate the leads against the terminal board so that the earth lead
is the last to detach from its terminal in the event of reverse pulling.
Connect the 3 phase phase leads to the terminals marked "1" phase phase
terminal marked " " " " 4 4 4 4 " " " " or "5"
following layout:
(this electrical connection layout is also available near the power supply terminal board). Tighten
the cable clamp on the back (at the bottom) of the appliance and replace the left side. The
cable must correspond to those given in the "Technical specifications" table (paragraph 1.1).
The appliance must be connected to an equipotential system
according to current regulations.
This connection must be made between different appliances using the special terminal
marked with . The equipotential lead must have a minimum diameter of 10 mm
equipotential terminal is on the rear of the appliance.

The oven must be supplied with softened drinking water with a hardness value of 0.5 to 3°F
(It is obligatory to use water softener to reduce the formation of scaling inside the cooking
chamber). The water pressure must be in the range of 100 to 200 kPa (1.0 – 2.0 bar). If the
water pressure exceeds 2.0 bar, install a pressure reducer device upstream. If the pressure is
below 1.0 bar, use a pressure pump to increase the level.
The connection to the water supply is done using the ¾" threaded solenoid valve on the
back (at the bottom) of the appliance (see fig. 1), fitting a mechanical filter with a cut-off cock
(before connecting the filter, allow a certain amount of water to flow out in order to remove
any waste from the pipe).

There is a drainage pipe on the back of the appliance (see Fig. 1) for emptying the cooking
chamber. A pipe of at least 30 mm internal diameter (DN30) must be connected to this pipe
that is resistant to the steam temperature. To avoid throttling, we advise using a rigid pipe
without any elbow bends along its length. The pipe must have a constant inclination of at least
5% along its length (the length is that from the outlet pipe from the appliance to the drain and
must not exceed 1 meter overall). The outlet pipe must flow into an open drain on the floor
(Fig. 2). If not, there must be a difference in height between the outlet pipe on the appliance
and the drain of at least 30 cm (see Fig. 3) to ensure the water flows out correctly. In conformity
with hygiene regulations in force, the pipe connected to the water outlet pipe on the appliance
must not be directly in contact with the outlet point.
