2.2 Control panel
1 Function knob
The oven's various functions are suitable for
different cooking methods. After selecting
the required function, set the cooking
temperature using the temperature knob.
2 Thermostat indicator light
When the indicator light is fixed, it indicates
that the oven is heating up to reach the set
temperature. Once the temperature has
been reached, the indicator light comes on
and goes off to indicate that the
temperature is being kept constant.
3 Temperature knob
This knob allows you to select the cooking
temperature.
Turn the knob clockwise to the required
value, between the minimum and maximum
setting.
4 Humidification knob
Dispenses steam to improve cooking. Turn
the knob clockwise to the 1position. Steam
will be dispensed until the knob is released.
5 Timer indicator light
When off, it indicates the beginning of
timed cooking. When on, it indicates that
timed cooking has finished.
6 Timer knob
This knob allows you to select manual or
timed cooking. Turn the knob to the symbol
for manual cooking or to the numbers
to select the minutes of cooking. Once the
countdown has finished, the knob will
automatically return to the “0” position, the
oven switches off and a beep sounds to
indicate the end of cooking.
For humidified cooking, place the
function/temperature knob at a
temperature greater than 150°C.

Use

EN
2.3 Other parts
Shelves
The appliance features shelves to position
trays and racks at different heights. The
insertion heights are indicated from the
bottom upwards (see 2.1 General
Description).
Internal ventilation
When the door is opened, oven ventilation
is automatically switched off (together with
the heating elements); it then resumes as
soon as the door is closed.
Interior lighting
The oven light comes on when the
appliance is running or when the door is
opened.
Safety thermostat
The appliance is equipped with a safety
device that triggers in case of serious
malfunction.
Only for the installer/technical support:
1. Unscrew the protective cover for the
thermostat with the dedicated tool.
2. To reset the safety thermostat, press the
button on the back.
Optional accessories
Original optional accessories can be
requested from Authorised Assistance
Centres. Use only original accessories
supplied by the manufacturer.
Contact Technical Support
immediately after the safety device
has triggered to check if there are
any faults.

Use
36
3 Use
3.1 First use
1. Remove any protective film from the
outside or inside of the appliance,
including accessories.
2. Remove any labels (apart from the
technical data plate) from the
accessories and from the oven cavity.
3. Remove and wash all the appliance
accessories (if fitted) (see 4 Cleaning
and maintenance).
4. Heat the empty oven at the maximum
temperature to burn off any residues left
by the manufacturing process.
3.2 Using the oven
Switching on the oven
To switch the oven on:
1. Select the cooking function using the
function knob.
2. Select the temperature using the
temperature knob.
3. Select the cooking time (up to 60’), or set
manual cooking using the timer
knob.
Cooking modes
The oven is designed for a
maximum load of 12 kg.
Defrost
The movement of air at room
temperature causes frozen food to
defrost quickly. This type of rapid
defrosting is ideal as the taste and
appearance of the de-frozen food,
whether previously deep-frozen or
frozen in the freezer, remain
unaltered.
Fan with circulaire
The combination of the fans and the
circulaire heating elements
(incorporated in the rear of the
oven) allows you to cook different
foods on several levels, as long as
they need the same temperatures
and same type of cooking. Hot air
circulation ensures instant and even
distribution of heat. It will be
possible, for instance, to cook fish,
vegetables and biscuits
simultaneously (on different levels)
without odours and flavours
mingling.

Use
37
EN
Static
As the heat comes from above and
below at the same time, this system
is particularly suitable for certain
types of food. Traditional cooking,
also known as static cooking, is
suitable for cooking just one dish at
a time. Perfect for all types of roasts,
bread and cakes and in any case
particularly suitable for fatty meats
such as goose and duck.
Grill
The heat coming from the grill
element gives perfect grilling results
above all for thin and medium
thickness meat and, in combination
with the rotisserie (where fitted),
gives the food an even browning at
the end of cooking. Perfect for
sausages, spare ribs and bacon.
This function enables large
quantities of food, particularly meat,
to be grilled evenly.
Grilling can only take place with
the oven door closed: opening the
door deactivates the heating
elements.
Fan-assisted lower element
The combination of the fan with just
the lower heating element allows
cooking to be completed more
rapidly. This system is
recommended for sterilising or for
finishing off the cooking of foods
which are already well-cooked on
the surface, but not inside, which
therefore need a little more heat.
Perfect for any type of food.
Cooking with humidification
Oven humidification does not take
place at temperatures lower than
150°C: lower temperatures cause
condensation and dripping.
Therefore, turn the temperature
knob to a value higher than 150°C
and wait until the (orange)
thermostat indicator light switches
off before starting the oven
humidification cycle.
It is not recommended to keep the
humidification knob turned for
more than 3 seconds at a time.

Use
38
3.3 Cooking advice
General advice
• Use a fan assisted function to achieve
consistent cooking at several levels.
• It is not possible to shorten cooking times
by increasing the temperature (the food
could be overcooked on the outside and
undercooked on the inside).
Advice for cooking meat
• Cooking times vary according to the
thickness and quality of the food and to
consumer taste.
• Use a meat thermometer when roasting
meat, or simply press on the roast with a
spoon. If it is hard, it is ready; If not, it
needs another few minutes cooking.
Advice for cooking with the Grill
• Meat can be grilled even when it is put
into the cold oven or into the preheated
oven if you wish to change the effect of
the cooking.
• We recommend placing the food at the
centre of the rack.
• With the Grill function, we recommend
that you turn the temperature knob to the
maximum value to optimise cooking.
Advice for cooking desserts/pastries and
biscuits
• Use dark metal moulds: They help to
absorb the heat better.
• The temperature and the cooking time
depend on the quality and consistency
of the dough.
• To check whether the dessert is cooked
right through: At the end of the cooking
time, put a toothpick into the highest point
of the dessert. If the dough does not stick
to the toothpick, the dessert is cooked.
• If the dessert collapses when it comes
out of the oven, on the next occasion
reduce the set temperature by about
10°C, selecting a longer cooking time if
necessary.
Advice for defrosting
• Place frozen foods without their
packaging in a lidless container on the
first shelf of the oven.
• Avoid overlapping the food.
• To defrost meat, use the rack placed on
the second level and a tray on the first
level. In this way, the liquid from the
defrosting food drains away from the
food.
To save energy
• Stop cooking a few minutes before the
time normally used. Cooking will
continue for the remaining minutes with
the heat which has accumulated inside
the oven.
• Reduce any opening of the door to a
minimum to avoid heat dispersal.
• Keep the inside of the appliance clean
at all times.

Cleaning the oven cavity
In order to keep your oven in the best
possible condition, clean it regularly after
letting it cool down.
Avoid letting food residue dry inside the
oven cavity, as this could damage the
surfaces.
Take out all removable parts before
cleaning.
For easier cleaning, we recommend
removing:
• The door
• Tray support frames
• The gasket.
In the event you are using specific
cleaning products, we recommend
running the oven at maximum
temperature for 15-20 minutes in
order to eliminate any residue.
For easier cleaning, remove the
door.

links up parts that are normally
earthed. Connect the appliances
appropriately using this terminal in
order to make sure that they are
equipotential.
If the phase voltage drops below
190V~, the performance of the
oven may suffer, not due to the
product itself.
The values indicated above refer
