4.2 Choosing a place for installation
An effective, safe and long lasting functioning of the appliance also
depends on the position in which it is installed. For this reason, it is advisable
to carefully consider where to install the equipment before it is delivered
Install the appliance in a dry and easily accessible place both to facilitate its
use and to carry out cleaning and maintenance. The area around the
equipment must be kept clear. It is particularly important to avoid obstructing
the cooling outlets located at the sides of the equipment.
The appliance must be installed
at least 20cm from the walls of the
room or from other equipment so that
the ventilation outlets located on the
sides of the oven are not obstructed.
Whilst in operation, cooking equipment
produces vapor and cooking smells that
compromise the integrity of a healthy
working environment
In the case of electric ovens, even if it is not obligatory, the installation
of an extraction fan and hood is recommended to improve conditions in the
working environment and to avoid damage to the ceiling of the area where it
is housed caused by hot, oily fumes.
A check must be made to ensure that the temperature and relative
humidity never exceed the maximum and minimum values indicted in the
specifications (see paragraph 3.4) even when the oven itself or other ovens
in the room are functioning.
Exceeding these values especially the temperature or the maximum
relative humidity can easily and unexpectedly damage electrical equipment
creating hazardous situations.
The manufacturer cannot answer for damage caused by ignoring
these abovementioned norms as well as the information in this manual.

dispersion capacity as the appliance itself. The efficiency of this system
must be correctly verified according to the norms in force.
The power cable must terminate with a plug to connect to the electrical
switchgear having a corresponding differential magneto thermal switch.
The equipment is not supplied with a power plug.
The coupling between plug and socket must be such that the earth
conductor is connected first and disconnected last and must have the right
dimensions for the rated current (see Table 3-1). Plugs and sockets for
industrial use of the type CEE17 are suitable or those which satisfy European
norm EN 60309.
The thermal circuit breaker must be calibrated to the total rated current and
the magnetic circuit breaker calibrated to the rated current (In the case of
ovens this is only slightly higher than rated current), while the differential
mechanism must be calibrated to the 30 mA current (see Table 3-1).
The electrical socket must be easily accessible and must not require further
location after the installation of the equipment. The distance between the
equipment and the socket must be sufficient to avoid stretching the power
cable
The power cable must never be trapped under the feet or
wheels of the equipment
If the Power cable is damaged it must be substituted by
customer support or by a qualified service engineer so as to avoid
any risk.
The manufacturer does not accept responsibility for damage caused
by failure to observe the abovementioned norms.
For the position of the electrical power connections, see Fig. 4.3.
4.6 Emissions from cooking appliance
ATTENTION! Proceed with the installation of the oven according
to the norms defined by current legislation in the country concerning
the installation of this typology of oven so as to guarantee the

The manufacturer cannot answer for damage caused by ignoring
these abovementioned norms as well as the information in this manual.
4.7 Checking before starting work
After completing installation of the unit a series of checks must be carried out,
listed as follows:
- check that the various disassembled parts have been assembled
- check the power cable
- check that the control panel is working
- If present, check that the ventilation hood is working
IMPORTANT - PRE-HEATING PHASE AT FIRST IGNITION
The components of the brand new oven (refractory stone bottom and metal
parts) need to be pre-heated before being used for the first baking.
When the oven is switched on the first time, it is necessary to HEAT IT
GRADUALLY IN ABOUT 5-6 HOURS (1°h=100°C - 2-3°h=150°C -
4°h=200°C - 5°h=250°C - 6°h=300°C). The max temperature has to be
reached at the end of this pre-heating phase.
This procedure is absolutely necessary to avoid damages to any part of the
oven.

5.2 System functional states
5.2.1 Standby on/off button
When on standby the panel is powered but no system function is enabled.
The general remote switch is disabled and the message OFF is displayed
on the set display on the control panel along with the current time
on the display with flashing seconds dot (between the second
and third figure, ½ second on, ½ second off).
All buttons on the panel are disabled except for the button (system on)
and the key, pressure on which will bring the system to clock setting
mode (see “programming” section).
Pressing the button, the system comes on, the last SET temperature
programmed is displayed on the set display , and the cycle used
prior to switching the oven off is displayed on the display.
5.3 Settings
5.3.1 Set temperature setting
To set the SET temperature use the and buttons until the desired
baking temperature appears on the display.
5.3.2 Upper and lower element setting
Pressing the buttons varies the time the oven heating elements remain
on. Each time the button is pressed increases this value by 1 unit, up to a
maximum of 9 units. Further pressure returns the value to 0.
NB. Each unit on the two displays corresponds to 5 seconds element on
time. For the remaining units the elements remain off. The total duration of
the cycle is 45 seconds.
The on time of the two elements can be varied at any time, even during the
baking cycle. The upper elements during the first part of the cycle while the
lower ones come on during the second.
For example, setting the upper elements to 6 and the lower ones to 5 gives
the following result:
5 10 15 20 25 30 35 40 45
Upper ON OFF
Lower OFF ON

_________________________________________________________________5. WORKING
____________________________________________________________________________
18 CITIZEN 6 - 9/MC, CITIZEN 6+6 - 9+9/MC DIGITAL VERSION
Note that with this setting, for the first 20 seconds only the upper elements
are on, so the oven uses half the total power. Over the next 10 seconds
both the upper and power elements are on, with the oven using full power.
In the remaining 15 seconds, on the lower elements are on, so the oven
once again uses half its available power.
5.3.3 Economy button
Pressing the economy button sets power values to pre-set levels
(upper 5 and lower 3) with the following result:
5 10 15 20 25 30 35 40 45
Upper ON OFF
Lower OFF ON
Note that with this setting, in the first 25 seconds only the upper elements
are on, with the oven using half power. Both elements are off for the
following 5 seconds. In the remaining 15 seconds only the lower elements
are on and so the oven once again uses only half power. This means that
throughout the cycle the oven never uses more than half power and for 5
seconds power consumption is zero.
A similar result can be obtained through manual power settings, if the sum
of upper and lower times is less than or at most equal to 9.
5.3.4 Start/Stop button
Pressing the start/stop button starts the baking cycle according to the
previous setting.
5.3.5 Oven light button
Pressing the oven light button switches on the light in the oven. Press
again to switch it off.
