- 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.
- Fit a main quadripole switch with fuses or an automatic switch
suitable for the values shown on the rating plate, to allow the
oven to be disconnected from the mains and that provide full
disconnection under overvoltage category III conditions.
NOTE:
The device selected should be in the immediate vicinity
of the oven and within easy access.
- The oven is delivered with the required voltage indicated on the
rating plate (See Fig.2).
- To carry out electrical connection, remove the protective cover
located on the rear side of the oven (Fig.10 item A). 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 an adequate cross-section (See TAB. 10) into the
cable raceway provided (Fig.10 item B) and then connect it to the
terminal board as illustrated (Fig.10 items F and G).
- When connection has been completed, check that the supply voltage,
with the appliance running, does not differ from the rated value by
more than ±5%.
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 Tab1).
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.10 items F and G). 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.10 item E).
It is marked with the symbol TERMINAL FOR THE EQUIPOTENTIAL
SYSTEM.

2.5.5
CONNECTING TO THE WATER SUPPLY
Connection to the water supply must be made in accordance with local
Laws and Regulations and flexible pipes for the connection to the
water supply network must comply with IEC 61770 and subsequent
modifications.
WARNING!
Use only the hose supplied to the equipment.
In any case never use tubes used.
WARNING!
A tap must be fitted upstream of the
appliance to shut off the water supply.
The 3/4 male gas type water filler (Fig. 10 item D) is located at the
rear of the oven. The working pressure must be between 1 and 1,5 bar.
WARNING!
Higher pressures may result in situations
that are dangerous for persons and harmful for the appliance.
The appliance must be connected to a supply of soft water.
For preference, a flexible pipe should be used so as to avoid even small
pressure changes in the water supply.
Leave the water to run through the pipe before connecting the oven.
If the oven is connected to a supply of hard water this will cause rapid
calcification of the steam generator.
WARNING!
In order to eliminate corrosion problems, the
Langelier index for the water used should be between 0 and +0.2.
NOTE:
The manufacturer declines any responsibility in the
event of failure to comply with the above safety precautions.

WARNING!
working. Do not touch it, or you will burn yourself.
WARNING!
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.
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.
For more even results, we recommend avoiding the use of
temperatures above those recommended for the type of product being
baked.
3.1.1
CHECKING NOZZLES
Check that the oven (rated gas category and type) is set up for the type
and 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!

The rated thermal capacity is achieved with the nozzle indicated in the
table (see technical data TAB.1), the air feed opening (fig.14) must be

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.

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.
