The vapour exhaust pipe is located at the rear of the oven (part. C –
fig. 7). Insert the perforated ring (part. B – fig. 7) into the vapour
exhaust and connect up.
NOTE: It is advisable to connect the vapour exhaust to a
chimney-pipe or to the outside using a pipe with a diameter of at
least 100 mm.
This pipe (part. A – fig. 7) must be inserted through the ring into the
oven exhaust duct. Any extensions must likewise be connected so
that the upper pipe fits into the lower one, as illustrated for the
connection described above.
If the outer exhaust pipe is very long it is recommended that a small
plastic tube be fitted at the base of the vapour exhaust to allow
drainage of condensation (part. D – fig. 7). This operation must be
carried out before the pipe is fitted into position.
2.5.2 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 for the supply to which the oven is to be connected
has been turned to the "off" position.
The rating plate contains all the information necessary for
proper connection.
WARNING! The appliance is set up for the voltage indicated on
the rating plate (FIG. 1), please contact the Manufacturer for
any changes in voltage.
2.5.2.1 BAKING CHAMBER ELECTRICAL CONNECTION
WARNING! For each individual baking chamber it is necessary
to install a main four-pole switch with a fuse or an automatic
switch suitable for the values shown on the plate, to allow the
appliances to be disconnected from the mains singly.
NOTE: The device selected should be in the immediate vicinity of
the appliance and within easy access.
The baking chamber is delivered with the required voltage indicated
on the rating plate (fig. 1).
To carry out electrical connection, remove the protective cover
located on the rear side of the baking chamber (fig. 8).
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 the cable into the cable outlet provided (part. A – fig. 9),
making sure you use a cable with a suitable section: see TAB.1 of
technical data, then connect it to the terminal as illustrated in figures
10A, 10B and 11, respectively.
When connection has been completed, check that the supply
voltage, with the oven running, does not differ from the rated
value by more than 10%
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. 10A – 10B – 11). It is marked with
the earth symbol and the earth wire most be connected to it.
These ovens must also be inserted in the unipotential system circuit,
and a terminal is provided for this purpose, located at the rear of the
oven (fig. 9 – part. B). It is marked with the symbol TERMINAL
FOR THE UNIPOTENTIAL SYSTEM.
When connection has been completed, check that the supply voltage,
with the oven 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 (see technical data).
2.5.2.2 PROVING OVEN ELECTRICAL CONNECTION
WARNING! The proving oven must be fitted with a general two-
pole switch with fuses or with an automatic switch suitable for
the values shown on the rating plate.
NOTE: The device selected should be in the immediate vicinity of
the appliance and within easy access.
The proving oven is delivered with a voltage of 230V 1N 50/60 Hz,
as indicated on the rating plate located at the rear (fig. 1).
To carry out electrical connection, remove the protective cover
located at the rear of the oven on the left hand side (fig. 12).
The connection cable must be provided 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 of suitable section (see technical data) into the cable
outlet provided (fig. 13 part. A), and connect it to the terminal board
as illustrated in figure 11.
When connection has been completed, check that the supply voltage,
with the oven 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 (see technical data).
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.11). It is marked with the earth
symbol and the earth wire most be connected to it.
These ovens must also be inserted in the unipotential system circuit,
and a terminal is provided for this purpose, located at the rear of the
oven (fig. 13 – part. A). It is marked with the symbol TERMINAL
FOR THE UNIPOTENTIAL SYSTEM.
2.5.3 CONNECTION TO THE WATER SUPPLY
Connection to the water supply mains must comply with the
regulations in force and flexible pipes for the connection to the water
supply network must comply with IEC 61770 and subsequent
modifications.
Connect a copper or iron pipe to the threaded connector provided
(fig. 9 part. C), which is located on the back of the baking chamber.
For the working pressure, please see the table of technical data.
WARNING! A water stop tap must be fitted for each baking
chamber
NOTE: The manufacturer declines any responsibility in the event
of failure to comply with the above safety precautions.
2.5.4 DRAINING OFF CONDENSATION
Connect a rubber tube to the connector provided (fig. 7 part. D).

OPERATION
3.1
PRELIMINARY CONTROL OPERATIONS
WARNING!
Before commencing start-up and programming of the oven,
always check that:
- all electrical and earthing connections have been properly
made.
- all vapour connection and discharge operations have been
properly made.
All control operation must be carried out by specialist
technicians with a regular license.
WARNING!
- The oven must always be under surveillance when in operation.
- During operation the oven surfaces, and in particular the glass,
become hot, so that care must be taken not to touch them so as to
prevent scalding.
- When opening the door make sure you stand at a safe distance
from any hot steam that may come out of the baking chamber.
- Never allow unauthorised persons to approach the oven.
Do not overload the trays with items and always abide by the
minimum space required between the items and the tray above.
Before placing items inside the oven, it is advisable to set the oven to
a temperature above the envisaged set point for cooking and then to
lower the temperature to the required setting.
