E n g l i s h | 3
III. INSTALLATION AREA
The appliance shall be installed in enclosed and well ventilated areas (not outdoors).
Before positioning the appliance, check the overall dimensions and the exact position of the
electrical connection.
It is advised to place the oven under an extractor hood or in such a way that hot fumes and odours
exit the oven via adequate ventilation to the outside.
The oven must be placed on a flat surface so that it does not slip or turn over.
The installation area must be able to support the weight of the appliance filled to maximum capacity.
See the information level on the back of the oven for the gross weight.
Make sure that it is placed so that the door may be fully opened.
Position it so that the back of the oven is easily accessible for maintenance and connection to the
main electrical supply.
The appliance is not meant to be fitted and a 15 cm space must be left all round it.
It is not advised to place it near heat, fryers or other hot liquids. If this is not possible at least
respect the following distances from machinery: 50 cm from the sides and above the appliance and
70 cm from behind.
Do not place the device near materials or containers of inflammable liquids (such as walls, furniture,
screens, gas canisters) as it can be a fire hazard. If this is not possible, cover the inflammable parts
with fire and heatproof material and check fire hazard regulations.
IV. PREPARING FOR INSTALLATION
Remove the outer packaging (wooden caging and/or carton box) and dispose of it in compliance
with the laws in force in the country of installation.
REMOVING PROTECTIVE FILM ETC.
Remove the protection film from the external and
internal walls. (See image)
Remove all information covering from the
inside, and take off all plastic packaging.
STAND
Do not use the appliance without stands.
The stands are already screwed to the underside of the oven.
If they are not used, this prevents airflow from cooling the electric parts and outsides of the oven
which causes over-heating and damage to components.
The oven will function correctly if placed level on a flat surface.

V. ELECTRICAL CONNECTION
WARNING: The main connection must be carried out by a qualified and authorised
technician according to national, international and local laws in the country where it is
installed.
Before the main connection, ensure that the frequency (…..Hz) and voltage (….V) meet the
requirements indicated in the in the information tag on the back of the appliance.
OVENS WITH CABLE AND SINGLE PHASE PLUGS
For appliances with cable and plug (single phase 220-240V) the plug merely needs to go into the
appropriate socket (the socket must be adapted for the supplied plug and must withstand the
voltage required by the appliance indicated on the information plate). The product must be
positioned so that the plug is always accessible.
The appliance comes with a certified cable and plug therefore they must not be tampered with or
modified.
Only the cable can be substituted: this must be carried out by a qualified authorized technician.

be yellow green.
WARNING: the yellow/green voltage wires in the ground cable must be 3cm longer than the
others.
Check that all the connections are tight before connecting the oven to the main.
WARNING: Erroneous connection could lead to overheating of the terminal board which
could lead to blowout and electric shock.
Check there is no static discharge between live and earth. Check the limit switch continuity between
the external casing and the ground wire of the main. It is advised to use a multimeter to carry out
these operations.
The appliance must be connected to the main using a H07RN-F cable.
EQUIPOTENTIAL CONNECTION
This connection shall be carried between the
different appliances with the terminal marked by
the symbol: (see image).
This terminal enables the connection of
Yellow/Green cable with a section between 2.5
and 10mm².
The appliance shall be included in an
equipotential system whose efficiency shall be
duly verified according to the provisions of the
laws in force.

specialized authorized technician.
Any maintenance, installation or repair work must be carried out by qualified authorized personnel
by contacting the Assistance Centre. Before carrying out any operation the appliance must be
disconnected from the main and wait for it to cool down.
Before moving the appliance from its position, check that the electricity connections (electric cables)
are correctly disconnected.
If the appliance is on wheels check that electric cables, pipes or anything else are not damaged
while moving it. Ensure the break is on. Avoid placing the device near heat (such as fryers etc.).
After carrying out the task and replacing the appliance in its initial position, check that the electric
supply is connected correctly.
V. MAINTENANCE IN CASE OF BREAKAGE
If the appliance breaks, disconnect it from the electrical main.
Before ringing Customer Service, check the chart below.

E n g l i s h | 10
If the problem persists we advise you to consult a retailer of the manufacturer for Assistance
Service specifying the problem and supplying your the code (Art.) and appliance Ser N°. This
information is provided on the INFORMATION PLATE on the back of the machine.
SPARE PARTS
Use only authorized parts for product repair. All interventions shall be carried out by authorized and
specialized technical personnel. Contact the Assistance Centre to request spare parts.
VI. ADVICE DURING COOKING
Where the grill is used to cook fatty food such as roasts or poultry it is advisable to insert a
container on the bottom of the cooking chamber to collect the fat during cooking.
While cooking food with full containers or filled with liquids, ensure
they do not spill, both during and after cooking on taking them out of
the oven. Scalding danger!
When ovens are placed on proving cabinets, stainless steel tables or
other ovens, it is not advisable to use shelves so high that the inside of
the oven is not at eye level. Scalding danger!
Always clean accessories before use.
To cook food perfectly and uniformly it is not advised to use deep baking trays because they would
prevent the correct air circulation. There must be a space of at least 2cm between the top tray and
food.
To cook uniformly do not overload the oven and make sure baked goods or bread face the right
direction toward airflow in the cooking chamber.

Correct use of core probe: insert in the thickest part of the food from top to bottom until the centre is
reached with the core probe.
To counteract the loss of heat through opening the door to put food in the oven, it is advised to
preheat to at least 30 °C higher than the desired cooking temperature.
In case of interventions on the food, leave the door open for the least time possible, so as to prevent
the temperature within the oven from dropping to a point of jeopardizing successful cooking.
WARNING: it is advisable to open the door twice: keep the door ajar (3-4 cm) for 4-5’’, then
open completely. This is to prevent heat and steam causing annoyance or burns.
DEFROST
The oven can be used for accelerating the defrosting process for foods to be cooked, by using
forced air at ambient temperature or at lower temperature (depending on the size of the product to
be defrosted). This guarantees quick thawing of frozen products without altering their taste and
aspect.
PREHEATING
To avoid the effects of heat loss when the oven door is opened to place food inside it is advised to
preheat to at least 30 °C higher than the desired cooking temperature.
