2.0 INSTALLING THE APPLIANCE
Read this handbook through carefully as it provides important information to guarantee a safe installation,
use and maintenance.
The appliance must be installed only and exclusively by qualied personnel following the instructions
given herein and in compliance with current laws in force.
The water, electricity and the
premises on which the appli-
ances are installed comply with
the relative installation and safety
standard.
Install the oven on aerated prem-
ises and level with the adjustable
feet, keeping at least 6 cm be-
tween the bottom of the oven and
the supporting surface on which
the feet stand.
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, as illustrated in gure 2.0A.
Take the protective lm 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, (Fig. 2.0A).

2.2 ELECTRICAL CONNECTION
When the appliance is delivered it is set to work at the voltage given on the rating plate afxed 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.
Before connecting the cable, remove the steel protection
xed to the ovens base with its specic screws, (see Fig.
2.2A) 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 specications of the exible cable for the electrical con-
nection should be no lower than those of the type with rub-
ber insulation H07 RN-F, with the cross section of the wires
as given in the technical data.
Install a circuit breaker of a suitable capacity upstream from
the appliance, making sure it has an opening between the
contacts of at least 3 mm.
It is essential to connect the appliance to an effective earthing system; (Fig. 2.2) for this purpose the rela-
tive terminal with the symbol to which the earth wire is to be connected is on the terminal board.
The effectiveness of the equipotential system of which the appliance
is part of, must conform to current standards. Connect using the
screw you nd 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
2.2A-CHECKING MOTOR ROTATION DIRECTION
(only for three-phase motors).
Check that the fans’ rotation direction is the same as that of the arrow
on the stainless steel air-conveying panel, located inside the oven. If
they are rotating in the opposite direction, reverse two phases on the
supply terminal board.

2.3 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 lter on the water inlet pipe.
Always connect to the cold water.
In Convection + Humidication models, the solenoid valve (B)
supplies the steam generation in Combination cycle (Fig. 2.3A).
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.
2.3B).
The water must be suitable to human use with the follow-
ing characteristics:
Temperature: included between 15 – 20°C
Total hardness: included between 4 and 8 °f (French de-
grees), it is advisable to install a softener upstream 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 100 and 200 KPa (1 – 2 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.

2.4 PLUMBING – WATER DRAINAGE
Drainage for the water is at the back of the oven and must be
connected directly to the end of the stainless 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 pressure with the appro-
priate 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.
Important: The drain system must be installed so that any
vapours coming from the open drain do not enter the aeration
vents under the appliance. (Fig. 2.4 and 2.4A).

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 xing 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 tempera-
ture drops.
3.0E Oven safety thermostat: disconnects the heating element or the gas valve when anomalies re-
lated to overheating occur. Subsequent re-set 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 + humidication models): it
comprises 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).
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
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 is closed.
3.2 CHECKING THE FUNCTIONS
Start the appliance following the “USER MANUAL”.
Test the water pipes for leaks.
It is essential to explain to the user exactly how the appliance works and to supply him with the instruction
handbook that he must follow when using the oven.

USE AND MAINTENANCE
For a correct comprehension of the terminology used in the following paragraphs, we underline that coo-
king phase is the period of time in which the oven carries out one of the following cooking modes:
Convection hot forced air
(temperature range between 50 - 270°C)
Combination hot forced air and steam
(temperature range between 50 - 270°C)
Steam
(temperature range between 50 - 100°C)
