therefore, any other type of use is strictly forbidden in order to assure, at any time, the safety of the
authorized operators, as well as the efficiency of the oven itself.
INSTALLATION
Verify that the electrical set-up corresponds with the numbers of the techincal characteristics on the
small plate at the back of the oven. The characteristics of the electric socket must be compatible with
the plug installed on the cable.
The place where the oven is installed must have the following enviromental characteristics:
 To be dry;
 Water sources at safe distance;
 Adequate ventilation and lighting corresponding to hygene and security rules following the

To connect the machine to the electric network it is necessary to proceed as follows:
1) connect to the wires to the terminals L1—L2—L3—N —of power cord type H07RNF 3G X “x”
mm²unsheathed with ferule;
2) put together the other end of the cable and a plug, which is normalised and polarised (the
distinction between phase and neutral must be unequivocal.
3) to connect the oven to 230 V single phase is sufficient to make a bridge between L1-L2-L3 with
the special plates present in the terminal box
ELECTRIC CONNECTION
THE ELECTRIC CONNECTION OF THE OVEN TO THE MAINS MUST BE
COMPULSORILY AND EXCLUSIVELY PERFORMED BY AN AUTHORIZED
TECHNICIAN (ELECTRICIAN) SATISFYING THE TECHNICAL AND PROFESSIONAL
REQUIREMENTS STATED BY THE REGULATIONS IN FORCE IN THE COUNTRY OF
USE OF THE OVEN, WHO MUST ISSUE A DECLARATION OF CONFORMITY FOR
THE INTERVENTION PERFORMED.
FOR DIRECT CONNECTION TO THE NETWORK, YOU MUST HAVE A DEVICE THAT
HAS A CONTACT GAP TO ENSURE THE COMPLETE DISCONNECTION, IN THE
CONDITIONS OF OVERVOLTAGE CATEGORY III, IN ACCORDANCE WITH THE
RULES FOR INSTALLATION.
L1 Clamp N.1
L2 Clamp N.2
L3 Clamp N. 3
N Clamp N. 4 or N. 5
Clamp N. 6
ONCE THE ELECTRIC CONNECTION HAS BEEN PERFORMED, THE AUTHORIZED
TECHNICIAN (ELECTRICIAN) MUST ISSUE A DECLARATION CERTIFYING THE
MEASUREMENT OF THE CONTINUITY OF THE EQUIPOTENTIAL PROTECTION
CIRCUIT.
THE APPLIANCE IS TO BE SUPPLIED THROUGH A RESIBASIC CURRENT DEVICE
(RCD) HAVING A RATED RESIBASIC OPERATING CURRENT NOT EXCEEDING 30
MA

TERMINAL BOX
The equipment must be connected with an equi-potential system . the connection terminal is located
near the terminal box. The bonding wire must have a minimal section of 10 mm ².

1 Warning light If lighted, it signals the operation of the resistor in use.
2 Thermostat
• Pos.0:it disables the operation of the resistor;
• Pos. 0-500°C :it enables the operation of the resistor
and sets the wished temperature.
3 Thermometer Indicates the temperature in the baking chamber.
4 Switch heating element • Pos. I: It enables the operation of the resistor;
• Pos. 0: It disables the operation of the resistor.
5 Chamber lamp switch • Pos. I: It switches on the light in the oven chamber;
• Pos. 0: It switches off the light in the oven chamber.

10
The first commissioning must be carried out as follows:
1) Clean the front of the oven with a dry, soft cloth to remove any residue;
2) Connect the plug to the socket;
3) Push “ON/OFF” button;
4) Set the oven temperature to 150°C
5) Let the oven work for about 1 h.
6) Turn the oven off by pressing ON/OFF button;
7) Open the door for about 15 min in order to let eventual vapors and smell go out;
8) Close the door and repeat the process described in Section 4) at the temperature of 300°C;
9) Let the oven work for about 1 h;
10) Switch the heating elements off by putting “ON/OFF” button in off position.
Remove the polystyrene underneath the refractory stones and the protective film avoiding using
tools that can damage the surfaces.
FIRST COMMISIONING
TURNING ON OVEN
1) Connect the plug to the socket;
2) Push the “ON/OFF” button;
3) Set the oven temperature to desired
4) Once the oven has reached the desired temperature, it is possible to insert the pizza in the oven
for the backing;
5) Open the oven manually using the suitable handles;
6) To switch the light on, press the oven lamp button;
7) Insert the pizza and/or the pizzas to be backed using suitable devices. It is important to avoid
leaving the door open for too long, since the temperature drops down.
8) Close the door again and check the backing through the glass door;
9) The baking temperature varies if it is positioned directly on the refractory stone or on a baking
pan. In the first case, it is suggested to set the backing temperature at 280 °C for the bottom and
320 °C for the ceiling; in the second case, set 320 °C for the bottom and 280 °C for the ceiling;
10) When the baking process is over, open the door extract the pizza (or pizzas) and close the
door again.
TURNING OFF THE OVEN
Once the use of the oven has ended, proceed as follows:
For turning off the oven press the ON/OFF button.
FOR THE SAFETY REASONS, THE MAXIMUM TEMPERATURE ALLOWED TO BE SET IS
500°C.
THE FIRST COMMISSIONING CAN BE CARRIED OUT ONLY AFTER AN INSTALLATION
CARRIED OUT BY AUTHORIZED PERSONEL WHO WILL ISSUE A DECLARATION OF
CONFORMITY.

11
The clearing must be done every time the oven has been used following all the rules to prevent
malfunctioning of the oven and for hygienic purpose.
Cleaning of the refractory surface: this operation has to be performed with hot oven.
Once the temperature of about 350°C has been reached, turn off the oven, open the door and
clean the surface using a brush in vegetable fiber equipped with a long handle in order to avoid
the contact with the oven hot parts.
External clearing of the oven: (surfaces in stainless steel, inspection WIDE and control panel):
this operation has to be performed with cold oven.
BEFORE PERFORMING ANY TYPE OF MAINTENANCE INTERVENTION, IT IS
COMPULSORY TO DISCONNECT THE PLUG OF THE OVEN FROM THE POWER
SUPPLY OUTLET.
MAINTENANCE
CLEANING
For any intervention of supplementary maintenance, repairing and/or replacement refer exclusively to
the authorized dealer where the oven has been purchased and/or to an authorized technician satisfying
the technical and professional requirements stated by the regulations in force.
IT IS RECOMMENDED TO THE OPERATOR IN CHARGE TO USE PROPER GLOVES
AND SUITABLE CLOTHING TO AVOID BURNINGS.
IT IS FORBIDDEN TO USE THROWS OR DRIPS OF WATER, ABRASIVE OR
CORROSIVE SUBSTANCES, AND ANYTHING ELSE THAT CAN DAMAGE THE
COMPONENTS, COMPROMISE THE SAFETY, AND BE DANGEROUS FROM AN
HYGIENIC POINT OF VIEW.
When dismantling the oven, compulsorily observe the provisions of the regulations in force.
