disconnected in case of overtemperature inside the
baking chamber.
4.4 - USER’S AREAS (Fig 3)
During the oven functioning, user is in front of it, in order
to be able to easily insert and remove the pizza through
the door (1) (see Fig.3 “O” position).
To carry out maintenance operations, technician’s
position may be on the rear or lateral side of the oven -
“T” position.
4.5 - RESIDUAL DANGER AREAS (Fig. 3)
Remaining danger areas: areas which cannot be
protected due to the particular concerned kind of
production;as to the oven, they can be read as follows:
•Door area and baking chamber inner area: risk of
burns.

5.1 - CONTROL BOARD AND PILOT LIGHTS ON DIGITALLY CONTROLLED OVENS (Fig 1)
On the oven, there are the following control elements:
1. Line key ON/OFF
Pressing it, the display (2) lights up, the lamp inside
the chamber lights up and the control elements are
energized.
2. Display
The set and real temperature as well as the ceiling
and bedplate resistance functioning percentage are
displayed.
3. Ceiling resistance capacity
Pressing it, the connection percentage value of the
upper resistances is displayed; to increase it press
(4), to reduce it press (5).
4. Increment key
To increase the values to be set.
5. Decrement key
To reduce the values to be set.
6. Bedplate resistance capacity
Pressing it, the connection percentage value of the
lower resistances is displayed; to increase it press
(4), to reduce it press (5).
7. Handwheel opening/closing
By turning towards , the chimney damper opens;
by turning towards , the chimney damper closes.
Temperature setting
Onthedisplay(2) the real oventemperatureisdisplayed,
to modify the set temperature press or , on the
display the set temperature is displayed, then press the
key within 5 seconds to raise or reduce the
temperature. After approximately 10 seconds from the
temperature setting, a temperature self-entering occurs
and the real oven temperature is displayed.

5.2 - MANUAL OVEN CONTROL BOARD (Fig 2)
On the oven, there are the following control elements:
1. Line key ON/OFF
Pressing it, the display (2) lights up and the control
elements are energized.
2. Display
The set & real temperatures are displayed.
3. Handwheel opening/closing

4. Adjustment hand grip for bedplate resistance
capacity
By rotating the hand grip (4) clockwise, the bedplate
resistance percentage capacity is increased,
counterclockwise it is reduced.
5. Adjustment hand grip for ceiling resistance
capacity
By rotating the hand grip (5) clockwise, the ceiling
resistance percentage capacity is increased,
counterclockwise it is reduced.
6. Increment key
To increase the temperature value.
7. Decrement key
To reduce the temperature value.
