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 the maximum.
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, connection to the mains sockets,
and water.
The appliance is not meant to be fitted and a 5 cm space must be left all round it.
Do not position other heat sources like, fryers or hotplates, near the oven. 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 heat-
proof material and by checking fire hazard regulations.
4. PREPARING FOR INSTALLATION
Remove the outer packaging (wooden or carton box) and
dispose it in compliance with the laws in force in the
country of installation.
REMOVING PROTECTIVE FILM ETC.

EN
For direct connection to the mains, it is necessary to interpose a device between the equipment and the same
mains, sized for the load, that ensure its disconnection. The contacts must have an opening distance enabling
the full disconnection, in conditions of over-voltage category III, per compliance with installation regulations.
This device also must be located in a place and in a manner to be easily accessible at any moment by the
operator.
OVENS WITH CABLE AND SINGLE PHASE PLUGS
For appliance 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 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. The earth wire
must always be yellow green.
APPLIANCE NOT SUPPLIED WITH CABLE WITH
THREE PHASE TERMINALS
Articles supplied by us come with terminals such as in the image. To connect to the mains see the label in the
manual and stuck to the lower part of the back of the appliance near the Information Plate .
The oven must be connected to the electricity with a rubber cable such as H07RN-F.
WARNING: the yellow/green voltage wires in the earth cable must be 3cm longer than the others.
The oven must be connected directly to the mains and must have an easily accessible switch from the start
,installed for the device according to the national, international and local laws in the country where it is in-
stalled. This switch must separate polarization guaranteeing complete disconnection in accordance with the
overvoltage III category.
Correct earthing is obligatory and the earth wire must not be operated by the protection switch.
CABLE CONNECTION
Proceed as follows to connect the power supply wire to the terminal board:
• ( A1 ) Loosen the tops of the cable gland and open the bottom part of the back of the appliance by loosening

the screws.
• ( A2 ) Feed the new cable through the cable gland. Connect the cable voltage to the terminal strips following
the connection diagram on the label on the back of the appliance. Only connect what is indicated inserting the
copper bridge and the electricity cable together under the screws, in the tightening direction, so the cable and
the bridge are tightly fixed by tightening the screw. The type of cable to be used (HO7RN-F) is indicated on the
label for each connection and the voltage sections in mm².
• ( A4 ) Close the bottom part of the back of the appliance by tightening the screws and fit the cable by tight-
ening the cable gland top.
Erroneous connection could lead to overheating of the terminal board which could lead to blowout and electric
shock.
Check that all the connections are tight before connecting the oven to the mains.
PE = Yellow/Green: “EARTH” protection conductor.
N = Blue: neutral conductor.
L1, L2, L3 = Brown, Grey, Black: live conductors
Check there is no static discharge between live and earth. Check the limit switch continuity between the ex-
ternal casing and the earth wire of the mains. It is advised to use a multi tester to carry out these operations.

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 ca-
ble with a section between 2.5 and 10mm² .
The appliance shall be included in an equipotential sys-
tem whose efficiency shall be duly verified according to
the provisions of the laws in force.
6. WATER CONNECTION
Make sure the device is placed near a water connection.
Before connecting the device,
allow enough water through to remove any remnants in
the piping so that they did not get into the magnetic valves.
It is necessary to install a shut-off valve and mechanical
filter between the plumbing and the device. On the back of
the device, in the area marked with a label, the convection
oven has an input G 3/4’’ with a filter.
The inflowing water shall have a pressure value com-
prised between 150 (1,5 bar) and 200 kPa (2bar) and a
maximum temperature of 30°C. If the inflow pressure
value exceeds 200kPa (2bar), a pressure reducer will have
to be installed, calibrated at 200kPa
(2 bar).
WATER TREATMENT
In order to ensure trouble-free operation of the device, the water should have a hardness of maximum 5°dH to
prevent lime deposits. For higher values a water softening station should be installed first.
7. FUMES DISCHARGE
Hot fumes and odours are emitted from the cooking chamber during cooking. This is located at the top part
of the back of the oven. Do not place objects on the discharge so as not to hinder the outflow of the fumes
and hence avoid causing damage thereto. It is advisable to position the oven under a suctioning or ensure
adequate ventilation to outside for hot fumes and odours through a pipe no smaller than the oven drainage.
Avoid bends and blockages.
8. STACKING OVENS
Stacking several ovens requires the use of the special kit which keeps the correct distance between the two
ovens.
