3.0 CONTROL AND SAFETY DEVICES

The ovens are equipped with a set of control and safety devices for the electric and hydraulic circuits.
3.0A 2A fuse: it is in the auxiliary circuit to protect against short circuiting of the electrical system and is in-
side its own support on the contactor's fixing bracket.
3.0D Motor overload protection: a thermal probe disengages the motor when, for various reasons, there is
an overload. When the overload protection triggers it stops the motor and also disconnects the heating ele-
ments or the gas valve. The probe is reset automatically when motor temperature drops.
3.0E Oven safety thermostat: disconnects the heating element or the gas valve when anomalies related to
overheating occur. Subsequent re-set will have to be done manually when causes for thermostat operation have
been determined.
3.0F Door micro switch: it stops the oven working when the door is opened.
3.0G Thermostat system for condensation of discharge steam: it
comprises a solenoid valve controlled by a thermostat whose sensor is
housed in contact with the discharge.
The solenoid valve, via the injector (G), lets cold water into the drainpipe
to condense the steam when a temperature of 90°C is reached.
Removing the side panel of the oven and acting on the F3 adjuster, it's
possible to modify the condensation system in the following way: if you
turn the thermostat pin F3 counterclockwise until you hear a click, the
function is disabled.
If you turn the pin counterclockwise without reaching the limit stop, steam
condensation system activates when the temperature in the drain pipe is
around 30 °C.
If you turn the pin counterclockwise till limit stop, condensation system
activates when the temperature inside the drain is around 90 °C.
In our factory the ovens are supplied with F3 thermostat regulated at 90
°C.

3.1 REPLACING SPARE PARTS

The replacement of damaged parts must be done only by qualified personnel.
To request the manufacturer parts to be replaced must be provided the oven model and serial number.
These data can be found on the rating plate attached to the oven (see par. 1.4).
Before starting to replace spare parts make sure, for safety reasons, that the electricity main switch is off
and that the water on-off valve are closed.

3.2 CHECKING THE FUNCTIONS

After completing the installation of the oven is necessary to perform a leak test to the water network.
The installer must check with suitable measurement instruments that the air noise emissions have
a level of sound pressure type weighed A, less than 70 dB (A).
The label ISO 3864-1 here on the side must be stuck on a visible surface, 1,6 mt
height from the ground.
On floor models, the label is already stuck in the suitable position.
On table models, the label is supplied along with the documentation and must be
stuck after installation on a visible part of the appliance at 1.60 mt from the ground.
The installer must verify proper operation of the oven, providing the necessary instructions
to the customer and give this instruction manual that the user must follow carefully.
IMPORTANT:
Before the operator turns the oven on and uses it for any cooking or washing cycle, it is necessary that the install-
er or a qualified technician checks all the connections have been done up to the instructions stated in our manual.
The technician or the installer must therefore check as follows:
• The oven must stand (horizontal position) and be fixed on a stand or a shelf, that can guarantee stability.
• Wiring connection must be effected according to the directives and the feed cable section must be no lower than
the one indicated in the manual.
• Pressure and hardness of the water must comply the values indicated in this manual;
• If the oven is supplied with drain pipe, this must be connected properly and the materials used should withstand
the working temperature.
After you have checked everything, open the water on-off valve, eventually the gas on-off valve and the protec-
tion switch, all installed upstream.
The installer must check the proper functioning of the oven and give to the operator necessary instructions for a
correct use of the oven, and also verify that the operator owns a copy of this manual.
At the end the installer must fill in and sign the chart for correct installation and give it to the custo-
mer, who will keep it for all warranty period of the oven.
