We thank you for the trust you granted us when you purchased our
product and advise you to carefully read this guide before using the
ovens.
This document contains all the information you need for the correct
use and maintenance of the oven.
The purpose of this guide is to allow the user, most of all the direct
user, to take all the measures and prepare all the equipment and the
necessary materials for a safe and long-lasting use of the oven.
This guide must be consigned to the person in charge of its use who
shall keep it in a suitable place, in order to make it available for consul-
tation and for the ordinary maintenance of the oven. In case the oven
is resold, the guide must be consigned together with it.
This guide is also intended to be used by the technician when per-
forming commissioning and extraordinary maintenance operations.
The intended use and available congurations of the machines are
the only ones approved by the producer; do not attempt to use the
machines in a way which would not comply with the indications sup-
plied by the producer.
The intended use indicated is only valid for machines having full
structural, mechanical and system eciency.
The producer refuses to accept any liability deriving from improper
use or use by untrained personnel, from ‘do-it-yourself’ changes or
repairs performed by unauthorized personnel and from use of non-
original spare parts or non-specic for the oven model.
1.1 Reference guide
Also please pay attention to the text in bold, with LARGER or under-
lined fonts, because they refer to particularly important information
or operations.
The guide must be kept until the nal disposal of the machine in an
adequate place, making sure it is always available for consultation in
its best conservation state. In case of loss or deterioration, the substi-
tute document will have to be requested directly to the producer or
the reseller.

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
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 ecient 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 mm2 connected to the clamp marked with the
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 o 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.
