3 Constructive principles
3 1 Cooling tangential system
The cooling system of the door ensures it has a continuous flow of air passing through it, eliminating residual heat and
external heat expel. This circulation is carried out by a mechanical fan (Tangential or Centrifugal) which creates the
flow of air passing through the slits in the door, as schematically indicated below.
this drawing shows the air flow created by a moto-tangential
fan .
The air is sucked from the surrounding room and spreads
through the door and expelled in the temperature ( the lower
temperature) which is expelled towards the bottom side.
On the other hand, the double o en cookers (ex: SUK62), the air flow is created thanks to a moto-fan (tangential)
whose air flow passes through slits positioned on the upper door and under the hob as shown in the following
drawing.
This drawing shows the air flow created by a moto-
tangential fan.
Hot air suction mo ement : the room cold air is sucked
and passes through the slits obtained on the front panel
and through the upper door , then the air is expelled from
the back slits.
The lower door has 4 glasses, not cooled.

1Top element + bottom element (conventional nad static cooking):
Wit eat supplied from above and below simultaneously, t is system is suitable
for cooking foods of all kinds.In conventional cooking, also known as
t ermoradiant cooking, it is preferable to cook one dis at a time. Ideal for roasts
of all kinds, bread and pies, it is particularly good for fatty meats suc as goose or
duck.
2Grill element: T e eat provided by t e grill element allows to ave good grilling
results particularly medium/small pieces of meat it can also be used in
combination wit t e rotisserie (w ere installed) to brown foods at t e end of
cooking. Ideal for sausages, spare ribs and bacon. T ose ovens wit 7,9 and 9
functions, t e grill element is composed by a double element w ic allows t e
grilling on t e w ole supporting ob ( large grill). T is function on t ese models
allows to grill a great quantity of food in a uniform way, especially meat.
3Bottom element (final cooking):
Wit eat from below only, t is mode is used to complete t e cooking of foods
w ic require a ig er base temperature wit out browning. Ideal for cakes, pies
and pizzas
4Fan + circular element + top element + bottom element (turbo ventilated
cooking):
T e combination of t e ventilated cooking wit traditional cooking allows to cook
different kind of food wit rapidity and efficacy on more t an one level, wit out
mixing any smells or flavors. Ideal for large quantities of food t at requires intense
cooking.
5Snowflake:
Wit t e switc on t is symbol, no eating is possible even if t e t ermostat is
turned.
6Fan + top element+ bottom element:
w en t e fan works toget er wit traditional cooking, it ensures omogeneous
cooking even wit complicated recipes. Ideal for biscuits and cakes, even cooked
toget er on more t an one level
7Fan + grill element:
t e air produced by t e fan softens t e wave of eat w i c t e grill generates,
allowing optimum grilling, even wit very t ick food. Ideal for large cuts of meat
(ex. pork s inbone). T e models wit 7, 9 and 10 functions t e grill element
is composed by a double greater element in comparison wit t e traditional grill,
allowing exceptional results (rapid cooking and au gratin cooking of a
great quantity of meat).
8Ventola + resistenza circolare (cottura a ventilazione forzata o ventilata):
la combinazione tra la ventola e la resistenza circolare (incorporata nella parte
posteriore del forno) consente la cottura di cibi diversi su più piani, purc é
necessitino delle stesse temperature e dello stesso tipo di cottura. La circolazione
14

di aria calda assicura una istantanea ed uniforme ripartizione del calore. Sarà
possibile, per esempio, cucinare contemporaneamente pesce, verdure e biscotti
senza alcuna mescolanza di odori e sapori.
9Fan + central grill element
this function is available only on 7, 9 and 10 functions models, through the
simultaneous action of fan and heat of the only central element is excellent for
coo ing and rapid gratinate small quantities of food (specially meats), putting
together the grill dietetically advantages to the uniformity of the ventilated coo ing.
10 Fan + bottom element (delicate cooking):
the combination between the fan and the bottom element allows to end the
coo ing more rapidly. This system is advisable for sterilizer or to finish coo ing of
well coo ed food on the outside, but not internally, thus requiring a moderate high
heat. Ideal for any ind of food.
11 Central grill element:
this function is available only on models with 7, 9, 10 functions, allowing the action
of heat emission from the only central element, grilling small portions of meat and
fish, for preparing ebabs, toasted sandwiches and grilled vegetable side plates.
12 Fan:
By selecting this symbol ( where foresee) the defrosting function can be obtained
by putting the thermostat on the 0°C initial position, in fact, this symbol gives the
possibility to act on the thermostat, in order to activate the circular element at the
same time.
13 Fan + circular element + bottom element:
the ventilated cooking is combined with the heat coming from the bottom giving a
slight browning at the same time. Ideal for any kind of food.
14 Rotisserie: The rotisserie (where installed) wor s in combination with the grill
element to brown foods to perfection.
The symbols that are present on the pyrolytic oven show the possibility to use the
grill spit in combination with the central or large grill.
