1.3 TRANSPORT OF THE OVEN AND PACKAGING REMOVAL
Upon receipt of the oven and before installing it, check the packaging is intact and there are not visible
damages. Also check that along with the oven you receive also the documentation, consisting of:
•Instructions for installation, use and maintenance
•Chart to check correct installation
•Wiring diagram
•Label ISO 3864-1
Before bringing the oven to the point, where it must be installed, check the following:
•The doors are large enough to allow passage of the oven
•The floor supports the weight.
According to the model of oven, its dimensions and its weight, use suitable facilities to handle goods dur-
ing transport and installation, able to guarantee stability in order to avoid overturning, falls or uncontrolled
movements of the appliance or its components.
Keep the oven packed until you reach the site where the oven is going to be installed.
The packaging makes the handling of goods easier and protects the oven from accidental push.
During moving and installation of the oven, the installer must comply with accident-prevention regulations
in force at the place of installation (use of safety shoes, gloves, etc.)
Remove the packaging taking care not to damage the oven.
The adhesive film, that protects the surfaces made of stainless steel can be removed also after you have
positioned the oven on the corresponding stand or the support surface.
ATTENTION: Packaging materials and adhesive film are potentially dangerous.
For this reason, they must be kept out of the reach of children and properly disposed
of in compliance with local directives.
You should separate packaging materials (wood, cardboard, plastic...) and dispose of
them separately, in compliance with directives in force at installation site.
Note: Take the protective film off the stainless steel parts by hand before starting the appliance.
Do not use abrasive substances and/or metal objects.
Clear any adhesive residues using a sponge soaked in solvent.
If the oven is heated up before removing the adhesive film, the removal of the film and cleaning of residues
of glue will be much more difficult.

1.4 INFORMATIVE LABELS
On each oven there are applied some metal labels, that give important info concerning characteristics of
the oven, electric and plumbing connections and eventually the drain connection.
On the right hand side panel there is the label A.
The info contained on this label are:
•Name and address of the manufacturer
•Oven model
•IPX protection grade against water jet.
•Conformity to EC directives.
•Power input and power supply (single or three phase).
•Serial number of the oven
•Symbol of European Directive 2012/19/UE
Removing the right hand side panel, on the oven chassis you find
label B.
On this label the serial number of the oven is repeated.
In this way, the customer or the installer can find the serial num-
ber of the oven also when the label A is dirty or damaged.
In the back of the oven, near the connector for water connection
there is the label C.
Label C indicates water features necessary for a correct function-
ing of the oven.
Same features are listed at paragraph 2.3A of this manual.
Close to the drain there is the label D, containing info concerning
drain connection.

1.5 POSITIONING OF THE OVEN
The place where the oven will be installed must comply the followingrequirements:
•Be protected from atmospheric agents and have an adequate air circulation;
•Comply with regulations concerning safety at work;
•Have a room temperature between 5 °C and 35 °C with a humidification not higher than70%.
Place the oven and proceed with levelling using adjustable feet.
Keep a suitable distance at the back, in order the label of equipotential clamp is easy to see when the
oven has been installed. The same clamp must be easy to access to install equipotential cable after the
oven has been installed in compliance with our instructions.
Install the appliance in a position that allows access to the right side for installation, maintenance and
technical assistance.
Maintain the minimum distances between the oven walls, (rear and right side) and either the brick walls or
the other appliances.
Take the protective film off the stainless steel parts
by hand before starting the appliance.
Do not use abrasive substances and/or metal ob-
jects.
If the oven is placed on its supports, supplied by us
on request, make sure the centre hole of the feet
snap on to the support pin which will guarantee
stability.

1.7 ELECTRICAL CONNECTION
When the appliance is delivered it is set to work at the voltage given on the rating plate affixed on the right
side of the appliance.
The terminal board used for connecting can be accessed from the right of the appliance, removing the
side panel.
The effectiveness of the equipotential system of which the
appliance is part of, must conform to current standards.
Connect using the screw you find near the power cable’s
relief cable strain, marked with the word EQUIPOTENTIAL.
The Manufacturer declines all and every responsibility if this
important accident prevention norm is not complied with.
If the feeding cable is damaged, it must be replaced by the
technical service or in any case by similar qualified person-
nel, in order to avoid any risk.
Before connecting the cable, remove the steel protec-
tion fixed to the ovens base with its specific screws, insert
the cable in the clamp-connector and then in the terminal
board zone, passing through the hole with the gasket near
the terminal board.
Once the electric connection has been carried out, reas-
semble the steel protection previously removed.
The specifications of the flexible cable for the electrical
connection should be no lower than those of the type with
rubber insulation H07 RN-F, with the cross section of the
wires as given in the technical data.
Install upstream a device that can ensure disconnection
from the main, with an opening distance of the contacts,
able to guarantee complete disconnection of the category
overvoltage III, in compliance with installation rules.
It is essential to connect the appliance to an effective earthing system; for this purpose the relative termi-
nal with the symbol to which the earth wire is to be connected is on the terminal board.

2.3 WATER FEATURES
The water must be suitable to human use with the following characteristics:
Temperature: included between 15 –20°C
Total hardness: included between 4 and 12 °f (French degrees), it is advisable to install a softener up-
stream from the appliance that will maintain the hardness level at the mentioned values.
The oven’s running with water that has a higher hardness level will not be long before scale forms
on the walls of the oven and in this case the technical assistance required to repair such damage
is not covered by the guarantee.
Pressure: included between 150 and 250 KPa (1,5 –2,5 bar).
Attention: higher water pressure values result in increased water consumption and can compromise the
correct functioning of some components.
Maximum chloride concentration (Cl-): less than 150 mg/litre.
Chlorine concentration (Cl2): less than 0.2 mg/litre.
pH: more than 7.
Water conductivity: included between 50 and 2000 µS/cm.
Attention: Water treatment systems that bring to different values to the ones above mentioned automati-
cally invalidate the guarantee.
The use of dosing systems designed to prevent the build-up of lime-scale in pipes (i.e. polyphosphate
dosing systems) is also prohibited since it may impair the performance of the appliance.

2.5 HYDRAULIC CONNECTION –WATER INLET
The ovens have a water inlet coupling at the back. Always install an on-off valve between the appliance
and the water mains, making sure it is easy to operate.
We also suggest installing a cartridge filter on the water inlet pipe.
Always use a set of new water joints, eventual old joints must not be used again.
Plumbing connection must be always effected with cold water and rigid pipes.
Never use hoses to connect the oven to the water main.
In Convection + Humidification models, the solenoid valve (B)
supplies the steam generation in Combination cycle (Fig. 2.5A).
In Combi Direct models, the solenoid valve (A) supplies the
steam generation in Steam cycle, the solenoid valve (A1) in
Combination cycle and the solenoid (B) supplies the steam
condensation system that comes out of the drainpipe (Fig.
2.5B).

2.6 PLUMBING –WATER DRAINAGE
Drainage for the water is at the back of the oven and must be connected directly to the end of the stain-
less steel drainpipe.
The drain must have no trap and be made in rigid pipes that can withstand a temperature of 110°C.
Under no circumstances must pipe diameter be reduced. The actual pipe should be at atmospheric pres-
sure with the appropriate funnel type air intake.
If the drainpipe is clogged for any reason steam can escape from the door and bad smells can be created
inside in the oven.

3.0 CONTROL AND SAFETY DEVICES
The ovens are equipped with a set of control and safety devices for the electric and hydraulic circuits.
3.0A 2A fuse: it is in the auxiliary circuit to protect against short circuiting of the electrical system and is
inside its own support on the contactor’s fixing bracket.
3.0D Motor overload protection: a thermal probe disengages the motor when, for various reasons,
there is an overload. When the overload protection triggers it stops the motor and also disconnects the
heating elements or the gas valve. The probe is reset automatically when motor temperature drops.
3.0E Oven safety thermostat: disconnects the heating element or the gas valve when anomalies
related to overheating occur. Reset will have to be done manually when causes for thermostat operation
have been determined.
3.0F Door micro switch: it stops the oven working when the door is opened.
3.0G Thermostat system for condensation of discharge
steam: (optional in convection + humidification models): it com-
prises a solenoid valve controlled by a thermostat whose sensor
is housed in contact with the discharge.
The solenoid valve, via the injector (G), lets cold water into the
drainpipe to condense the steam when a temperature of 90°C is
reached (Fig. 3.0G).
Removing the side panel of the oven and acting on the F3 ad-
juster of the Pic.3.0G1, it’s possible to modify the condensation
system in the following way: if you turn the thermostat pin F3
counterclockwise until you hear a click, the function is disabled.
If you turn the pin counterclockwise without reaching the limit
stop, steam condensation system activates when the tempera-
ture in the drain pipe is around 30° C.
If you turn the pin counterclockwise till limit stop, condensa-
tion system activates when the temperature inside the drain is
around 90°C.
In our factory the ovens are supplied with F3 thermostat regu-
lated at 90°C.
3.0H Oven relief valve: its job is to adjust humidity inside the
cooking chamber.
The valve is manually activated acting on the knob (A)
(Fig.3.0H) on top of the door.

3.1 REPLACING SPARE PARTS
The replacement of damaged parts must be done only by qualified personnel.
To request the manufacturer parts to be replaced must be provided the oven model and serial number.
These data can be found on the rating plate attached to the oven (see par. 1.4).
Before starting to replace spare parts make sure, for safety reasons, that the electricity main switch is off
and that the water on-off valve are closed.
3.2 CHECKING THE FUNCTIONS
After completing the installation of the oven is necessary to perform a leak test to the water network.
The installer must check with suitable measurement instruments that the air noise emissions have
a level of sound pressure type weighed A, less than 70 dB (A).
The label ISO 3864-1 here on the side must be stuck on a visible surface, 1,6 mt
height from the ground.
On floor models, the label is already stuck in the suitable position.
On table models, the label is supplied along with the documentation and must be
stuck after installation on a visible part of the appliance at 1.60 mt from the ground.
The installer must verify proper operation of the oven, providing the necessary instructions to the customer
and give this instruction manual that the user must follow carefully.
IMPORTANT:
Before the operator turns the oven on and uses it for any cooking or washing cycle,
it is necessary that the installer or a qualified technician checks all the connections
have been done up to the instructions stated in our manual.
The technician or the installer must therefore check as follows:
•The oven must stand (horizontal position) and be fixed on a stand or a shelf, that can guarantee stability.
•Wiring connection must be effected according to the directives and the feed cable section must be no
lower than the one indicated in the manual.
•Pressure and hardness of the water must comply the values indicated in this manual;
•If the oven is supplied with drain pipe, this must be connected properly and the materials used should
withstand the working temperature.
After you have checked everything, open the water on-off valve, eventually the gas on-off valve and the
protection switch, all installed upstream.
The installer must check the proper functioning of the oven and give to the operator necessary instructions
for a correct use of the oven, and also verify that the operator owns a copy of this manual.
At the end the installer must fill in and sign the chart for correct installation and give it to the custo-
mer, who will keep it for all warranty period of the oven.
