ELECTRICAL CONNECTION

WARNING! Electrical connection must only be carried out by
specialised personnel, in compliance with current local state Electric
Quality Assurance Corporation requirements.
- Before starting the connection procedure, check that the earthing
system is provided in accordance with European EN standards.
- Before starting the connection procedure, check that the main
power switch has been turned to the "off" position.
- The rating plate contains all the information necessary for proper
connection.
2.5.3.1 ELECTRICAL CONNECTION
CHAMBER
WARNING! Each baking chamber must be fitted with a main
homopolar switch with fuses or an automatic switch suitable for the
values shown on the plate, to allow the single appliances to be
disconnected from the mains. The switch must have a contact aperture
of at least 3 mm.
NOTE! The device selected should be in the immediate vicinity of the
oven and within easy access.
Electrical supply for the equipment is 230 Vac 1 50/60Hz (see rating plate
fig.2 item A).
To carry out electrical connection, remove the protective cover located on
the rear side of the baking chamber (fig. 10).
The connection cable must be supplied by the installer.
When connecting to the power mains, it is necessary to fit a plug that
complies with the standards and regulations in force.
Insert a cable with a minimum cross-section of 3 x 2,5 mm
raceway provided (fig.11 item A) and connect it to the terminal board as
illustrated in fig.12.
When connection has been completed, check that the supply voltage, with
the appliance running, does not differ from the rated value by more than
±10%.
WARNING! The flexible wire for connection to the power supply
must have characteristics at least equal to the model with rubber
insulation HO7RN-F and must have a rated section suited to the
maximum absorption.
WARNING! It is essential that the oven be properly earthed. A
special earth terminal has been provided for this purpose on the
connection terminal board (fig.12). It is marked with the earth symbol
and the earth wire must be connected to it.
These ovens must also be included in the unipotential system.
terminal to be used for this purpose is located at the back of the oven
(fig.11 item B). It is marked with the symbol TERMINAL FOR THE
UNIPOTENTIAL SYSTEM.
2.5.3.2 ELECTRICAL CONNECTION OF THE LEAVENING
COMPARTMENT
WARNING! The compartment must be fitted with a main homopolar
switch suitable for the values shown on the plate, to allow the single
appliances to be disconnected from the mains.
NOTE! The device selected should be in the immediate vicinity of the
appliance and within easy access.
The leavening compartment is delivered with a voltage of 230Vac. 1N
50/60 Hz, as indicated on the rating plate (fig. 2-part C).
To carry out electrical connection, remove the protective cover located on
the left hand rear side of the compartment (fig.13).
The connection cable must be supplied by the installer.
When connecting to the power mains, it is necessary to fit a plug that
complies with the standards and regulations in force.
Insert a cable with a minimum cross-section of 3 x 2,5 mm
raceway provided (fig.14 item A) and connect it to the terminal board as
illustrated in fig.15. When connection has been completed, check that the
supply voltage, with the appliance running, does not differ from the rated
value by more than ±10%.
WARNING! The flexible wire for connection to the power supply
must have characteristics at least equal to the model with rubber
insulation HO7RN-F and must have a rated section suited to the
maximum absorption.
WARNING! It is essential that the oven be properly earthed. A
special earth terminal has been provided for this purpose on the
connection terminal board (fig.15). It is marked with the earth symbol
and the earth wire must be connected to it.
These ovens must also be included in the unipotential system. The
terminal to be used for this purpose is located at the back of the oven
(fig. 14-part B). It is marked with the symbol TERMINAL FOR THE
UNIPOTENTIAL SYSTEM.
WARNING! The manufacturer declines any responsibility in the
OF THE BAKING
event of failure to comply with the above safety precautions.

WARNING! Before commencing start-up and programming of the
oven, always check that:
all electrical and earthing connections have been properly made;
all gas and vapour exhaust connections have been properly made;
all control operations must be carried out by specialised technicians
holding a proper license.
For more even results, we recommend avoiding the use of temperatures
above those recommended for the type of product being baked.
3.1.1
Check that the oven (rated gas category and type) is set up for the type and
2
in the cable
family of gas supplied. If this is not the case, convert to the type of gas
available.
The oven must be put into operation using the nozzles foreseen for the
rated thermal capacity (see technical data TAB.1).
WARNING! MODELS P110G! The valve adjustment screws must not
be tampered with: they are calibrated and sealed in the factory. It is
necessary to intervene on the pressure regulator for the gas valve
(fig.17 item C) , to guarantee the correct thermal capacity (see
technical data TAB.1) on the P150G only
3.1.2
3.1.2.1 MODELS P110G
The rated thermal capacity is achieved with the nozzle indicated in the
The
table (see technical data TAB.1), the air feed opening (fig.21 item D) must
be at a distance X= see technical data TAB.1.
Operation depends on the inflow pressure available (see technical data
TAB.1):
Should the pressure be outside the values indicated above, advise those
responsible for the system and do not start up the oven until the cause has
been traced and eliminated.
3.1.2.2 MODELS P150G
Rated thermal capacity is only achieved by setting the gas valve pressure
regulator (fig.17 item C) as shown in 3.1.6, so as to guarantee valve outlet
pressure (fig.17 item B) the same as the one shown in the technical details
TAB.1; the air feed opening (fig.21 item D) must be at a distance X= see
technical data TAB.1, the nozzle needs to be the one listed in the nozzle
table (see technical data TAB.1).
Operation depends on the inflow pressure available (see technical data
TAB.1):
Should the pressure be outside the values indicated above, advise those
responsible for the system and do not start up the oven until the cause has
been traced and eliminated.

The rated thermal capacity is achieved with the nozzle indicated in the
table (see technical data TAB.1), the air feed opening (fig.21 item D) must

in the cable be at a distance X= see technical data TAB.1.
Operation depends on the inflow pressure available (see technical data
TAB.1).
Should the pressure be outside the values indicated above, advise the gas
supply company and do not start up the oven until the cause has been
traced and eliminated.
NOTE! Should an additional test be required for the thermal capacity,
it can be performed using the volumetric method.
3.1.3.2
Rated thermal capacity is only achieved by setting the gas valve pressure
regulator (fig.17 item C) as shown in 3.1.6, so as to guarantee valve outlet
pressure (fig.17 item B) the same as the one shown in the technical details
