1.3. Water connection
The water pressure must be of maximum (600
kPa)6bars.Ifthepressureofmainswateris
greater than this value, it is necessary to install
a pressure reducer upstream of the oven.
The minimum water pressure for the proper
operation of the oven must be above 3 bar
(onlyovenswithself-cleaning).
The oven has an inlet for softened water on the
rear bottom side of the oven. It will be on the
left side for ovens with 6 trays (g. 3)andto
the right for ovens with 10 trays (g. 4).We
always recommend installing a water softener-
descaler to bring the hardness of the water
entering the appliance to values between 6 °
and12°F(60-120ppm).
Beforeconnection,drainoffasufcientamount
of water to clean the pipe from metal residues.
Connect the "Water" pipeline to water mains
andinstallashut-offvalveandalteronthe
Make sure there is a minimum clearance of
50 mm on all sides between the oven and the
wall or the other equipment (g. 1).
All materials used for packaging are environ-
mentally friendly; they can be stored without
any risk or be disposed of according to local
regulations in force.
The oven should be levelled: to adjust the
height of the leveling feet proceed as shown in
g. 2, using a spirit level.
Unevenness or inclinations of a certain degree
can compromise the operation of the oven.
Remove the entire protective lm from the
external panels of the appliance, detaching it
slowly to remove all traces of adhesive.
Make sure that all openings and holes designed
for heat intake/discharge are not obstructed.

1.4. Drain connection
The oven is equipped with a water drain; this
device is placed at the bottom of the rear part
of the appliance and has a tube with diameter
of 40 mm.
Connect the pipe of the draining device (g.
5, ref. A).Thedrainingsystemconsistsofa
trap; it is advisable to connect the pipe to an
open funnel.
Make sure the internal trap is full of water,
otherwisellitupwithwaterthroughthedrin
present in the cooking chamber.
pipe.
Ensure that the shut-off valve is positioned so
that it can be easily operted by the operator
at any time.
Caution: if the water supply pipe gets
damaged, it should be replaced with a new
one while the old damaged one should not be

1.5. Collegamento elettrico
The electrical system shall be tted with an
efcient earthing system, as required by
the regulations in force. You can ensure the
electrical safety of the appliance only in the
presence of a compliant electrical system.
Before wiring, check the voltage and frequency
of the power grid to ensure that they comply
with appliance rated values given on the
technical data plate (g. 6).
For direct connection to the mains, you should
placed between the appliance and the network
a device, sized according to the load, which
ensures disconnection. Its contacts should
have a minimum opening distance that enables
complete disconnection under the conditions
of overvoltage category III, according to
installation rules; this device should also be
located so that it can be easily used by the
operator at any time.
Turn the master switch, to which the power
plug will be connected, to position 0 (zero).
Make the socket cable section checked by
qualied staff to make sure it suits the the
power absorbed by the device.
The oven is supplied with cable 400V 3N;
when you connected to a different voltage,
you need to open the top compartment by
loosening the fastening screws (g. 7) and
connect the appropriate cable to the power
terminal block. Refer to the table on the next
page (tab. 1).
To make the electrical connection refer to the
wiring diagrams annexed to this manual.
Insert the power cord into the hole of the cable
gland located on the left bottom side of the
oven.
Connect the cable to the terminal block follow-
ing the instructions given in tab. 1.
Secure the cable with the cable gland.
The feed voltage, when the machine is
operating, should not vary in relation to the
rated voltage by more than ± 10%.

and according to the technical and safety instructions given in this manual.
You should also check that the compliance of the following:
The ambient temperature in the location where the oven is installed should be greater than +4
° C.
The cooking chamber should be empty.
All packages must have been completely removed, including the protective lm applied on
oven's walls.
The vents and slits should be open and free of obstructions.
The parts of the oven that were disassembled for installation purposes should be reinstalled.
The master switch should be closed and the water shut-off valve upstream of the unit must be
opened.
Testing
Oven should be tested by completing a cooking cycle to verify that the equipment works properly,
without any anomalies or problems.
Turn on the oven using the master switch T1 g. 9 (nextpage)
Set a cooking cycle with temperature to 150 ° C, time set to 10 min. and humidity to 25%.
Press the key T2 (g. 9)“Start/Stop”.
The applinace must be included into an
equipotential system whose efcency is
checked in compliance with the standards in
force. For the connection use the clamp, placed
on the frame and marked with the symbol g.
8, to which you should connect a cable with
