4.6Water supply installation
If the unit is fitted with a humidifier, the use of an anti-lime filter at the water supply inlet and a check
valve is recommended. The oven has a ¾” connection for water inlet.
Besides, installing a “digimeter” or digital instrument for measuring the litres of water consumed by the
oven is recommended. In this way, you will know when the filter should be replaced.
Important: before connecting the water supply, check that there are no residues in the pipe. The pressure
of the incoming water should range between 2 and 3 bar, with temperature not highter than 30ºC. If
pressure is higher than these values, a pressure reducer at the inlet should be installed.
The inlet water must have a pressure between 1 and 3 bar, with a temperature not exceeding 30 ºC. If the
pressure is higher than these values, a pressure reducer should be installed at the inlet.
The inlet water must have a pressure between 1 and 3 bar, with a temperature not exceeding 30ºC. If the
pressure is higher than these values, a pressure reducer should be installed at the inlet.
4.7Salida de Gases
Los gases de salida pueden ser húmedos y llegar a una temperatura elevada, por lo que para canalizarlos no
utilicen tubos de materiales que no garanticen una absoluta estabilidad térmica de hasta 200ºC.
Para el tratado de los vapores de la cocción es posible adpatar un condensador que permitirá condensar los
vapores y expulsarlos a un desagüe. El horno esta dotado de una conexión en la parte posterior para dicha función.
4.8Vapour exhaust
The appliance does not necessarily require the use of an extractor hood, but if installed, the following
should be considered: Install a grease filter in the area protruding from the hood.

5.4Operation in manual cooking mode
When the oven is off it shows “off”on the top display, everything else will be off. Pressing on the ON/OFF
button turns the oven on. When the oven is on, the display shows the current temperature value inside the firing
chamber (value measured by the probe, “fixed temperature icon”) and the TIME/HUMIDITY display shows END
(clock icon on). Pressing the increase or decrease button allows you to set a temperature value (see point 6.2.2
“temperaturesetting”).
By pressing on the time button, it allows you the setting of the cooking time (see point 6.2.3)
By pressing the start/stop button, you can start or stop a cooking cycle.
5.5Temperature adjustment
At the first start-up, the current oven temperature will be shown on the display. By default, it will have a set
point temperature of 30ºC. At the end of the cycle, the previously set value will be displayed flashing.
When the furnace is switched on, pressing the increase or decrease buttons immediately allows you to set a
temperature value (adjustable temperature range from 30 –170ºC).
When editing the values, they will be show non the display flashing. To confirm the value, wait 8 seconds or
press button 3 “time”. Once the value has been confirmed, the flashing will stop. Pressing ON/OFF will delete the
set values.
5.6Cooking time adjustment
When the furnace is switched on, END appears in the lower display (display time). The time range can be set
between 00 hours 01 minutes –15 hours 59 minutes.
Pressing the “increase or decrease”buttons will allow us to set a time value. If we want to set a “continuous
mode”of cooking we have to press the decrease button until “INF” appears on the display. If we have chosen the
INF time it means that you have set an infinite time and the oven will be running until we press the Start/Stop
button. When editing the values, they are always shown flashing on the display. To confirm the values, either wait
8 seconds until they stop flashing or press button 3 “time”.
If we are in programming mode, and we need to dispense with one of the three phases, we simply set the
END time value for the phase we want to eliminate.
5.7Humidity adjustment

Ed.:21 –Ver.:01 –01/01/2021

During firing, the continuous pressure on the humidity button allows the activation of the solenoid valve for
a punctual steam injection.
To set the humidity by percentage, when setting the firing parameters, either in a manual program or in
programming, press the humidity button. At this point, “OFF”will flash on the lower display. Pressing the increase
or decrease button allows you to enter the desired humidity value. Humidity range: 0%-100%. To confirm, press
the humidity button again. After confirming, the humidity value dissapears from the display and the cooking time is
displayed. When pressing the Start/Stop button to start a firing cycle, if the cycle has a programmed humidity
percentage e.g. from 10% to 100%, it will not start injecting water until the actual temperature of the firing
chamber has exceeded 85ºC. When humidification is active, the humidity icon will be permanently illuminated
green when performing each injection.
During steam injection the steam icon will illuminate green. In case of coinciding with a fan rotation change
the injection will stop until the fan rotation change is finished.
5.8Automatic preheating
Automatic preheating allows us to preheat the oven before starting the cooking cycle to ensure that the
oven is always the desired temperature to start cooking. In this way we will compensate the lemperature loss that
exists from the moment we open the door and load the food. To start the cycle it will only be necessary to open
the door, introduce the food and close the door and immediately after that time will start to count down.
When the symbol “PRE” is illuminated, it means that the oven will preheat before cooking. During
preheating, the oven will rise 30ºC above the set temperature. Once the preheating is finished, the equipment will
emit an acoustic signal indicating that the product can now be placed in the oven.
To actívate preheating, press the time key for three seconds before starting cooking.
To deactivate the preheating, it can be done by pressing the time button for three seconds while setting the
cooking parameters, or by opening and closing the door once the cycle has started.
5.9Running a cooking cycle in manual mode
With the oven on and after having set the time and temperature values, pressing and holding the time
button for 3 seconds will activate preheating. Then press START/STOP to start the cycle. This will activate the
heating element, fan and humidification is programmed. Pressing start /stop stops the cooking cycle at any time
and the countdown is locked and the remaining time is shown on the display. If the set value was INF, the value
displayed will remain INF. Pressing the Start/Stop button again will restart the cooking cycle with the programmed
time.
During the cooking time:
- The upper display (temperature display) will show the actual value of the temperature inside the oven
measured by the probe (fixed temperature icon). The lower display (time display) will show the remaining time
in hours and minutes (when the set value is greater than 1 hour) and in minutes and seconds (when the set

Ed.:21 –Ver.:01 –01/01/2021
17
value is less than 60 minutes) If the INF value is replaced by a certain time, the countdown will start from the
time the value is set.
- At the end of a cooking cycle (the time icon is illuminated) the time display shows END flashing, the fans and
heating elements are switched off and a buzzer will sound for 1 min. If during this minute, a new time is set,
the oven will resume operation for the extra time added with the same temperature settings as before.
Otherwise by pressing the Start/Stop button the buzzer is silenced and the display returns to the normal
display.
Note: To extend the cooking cycle, simply press the time button and increase the value, then press the
time button again to confirm and the oven will resume cooking.
5 minutes after the cooking ending if there is no operation made over the oven, it will authomatically turn off.
