7.1 • As all ovens of the series are fitted with
an alternating fan motor (clockwise and
anticlockwise rotation), there is no need
for the fan to rotate in any particular
direction. Simply verify, when
commissioning the appliance, that
the fan is balanced and rotates freely.
Warning: the
20 x GN 1/1 and 20 x GN 2/1
models are equipped with two motors.
7.2 • When making the electrical connection you
need to take care that the neutral pin of the
terminal block corresponds to the neutral
wire of the supply line. If this connection is
not made correctly, the burners will not be
able to operate.
This error is signalled by the electronic
circuit board.
7.3 • Check also that the neutral registers
zero potential when tested. If not, the
fault already described in point three of
this section will occur. In this eventuality,
consult the installer of the building’s
electrical system.
7.4 • Ethernet connection
Use at least a category 5 network cable
for the data connection. The Ethernet
connection is located on the lower right-
hand side of the appliance.
