2 - INSTRUCTIONS FOR INSTALLATION AND MAINTENANCE
This switch must be installed in the permanent electrical system of
the room where the oven is installed and in close proximity to the
oven itself so that operators have easy access to it.
For the dimensions of the power supply line, of the general switch
and the cable refer to the data given in the technical data table (see
paragraph 1.3).
In order to connect or replace the power supply cable to the ter-
minal box of the oven proceed as follows:
1) Connect the terminal box placed on the backside of the oven to
the wires of the electric cable, as indicated in the illustrated electrical
EN
diagram.
Make sure the yellow/green grounding wire is longer than the others
(phase and neutral) of about 3 cms so that in case of pulling it is
going to be the last one to break loose guaranteeing the security of
the protection against electric shock.
2) Block the cable and close the lid of the terminal box.
Grounding
The oven must be connected to an efficient grounding system.
The yellow/green wire of the supply cable must be secured in the
clamp marked with the grounding symbol
The oven must be included in an equipotential system the connec-
tion of which will have to be performed with a cable having a mini-
mum section of 10 mm
symbol placed on the backside of the oven.

Connection to water supply grid
Connect the water supply tube to the 3/4'' connection piece of the
oven (X- Fig. 4).
The supply pressure admitted is minimum 200 kPa, maximum 300 kPa.

2.3 - Safety devices

The oven is equipped with the following protection and safety
devices:
• Cabinet safety thermostat (if present): in case of overheating of the
cooking cabinet, it intervenes by cutting off the chamber heating.
The safety thermostat (F1 - Fig. 5) may be reactivated only in manual
by pressing the red button after having removed the front panel in
order to reach the component. Before executing the operation make
sure you have disconnected the power supply.
• Door switch that interrupts the operation of the oven when the door
is opened: both the heating system and the cabinet ventilation fan
motor.
• Protection grilles preventing access to the moving parts of the coo-
king cabinet.
CAUTION!
All potential reactivation operations must be performed by
specialized technical personnel after the elimination of the cau-
ses of interruption.
