2) First time heating the oven
On the display, select the option First Heating and press
(OK).
The process of heating the oven for the first time is extremely
important to ensure its future proper functioning and avoid
structural problems. The first heating programme must be
executed in full and only after it has been completed does
the control panel enter normal operation mode. If there is a
power cut, the programme will restart in the last temperature
recorded with a 25ºC margin.
When the oven is turned on for the first time it will automati-
cally enter Ramalhos mode and show the message Function
Test and First Heating on the display.
You can use the and , buttons to select one of the
following operation options shown on the display:
1) Function Test:
On the display, select the option Function Test and press
(OK).
It is used to check the oven is functioning properly after in-
stallation.
During this phase the oven temperature will not surpass
50º C.
The whole process will be managed automatically by the
control panel.
Throughout the process, the display will show different infor-
mation alternately. For example:
Note
To return to Ramalhos mode, press the button to
turn the oven off and on again.
Note
The first heating process may take up to 3 hours.
END OF FIRST HEATING PROCESS
Once all stages of the first heating programme have been
completed the control panel will show the following infor-

will be done automatically.
Once the programmed baking time is over, an acoustic signal
will be heard and the message OPEN TO STOP will show up
on the display intermittently.
Open the oven door and unload the baked produce.
If the oven door is kept open for more than 10 seconds when
the product is unloaded, the oven will remain inactive until a

EDITING PROGRAMMES DURING THE BAKING CYCLE
Proceed as follows to alter the temperature or baking time
during a baking cycle (while the message BAKING IN COURSE
appears intermittently on the display):
• Temperature
1 - Press the temperature button on the display once to see
the selected temperature.
2 - Use ( ) or ( ) to alter the temperature.
3 - Press (OK) to set the desired temperature.
• Baking time
1 - Press the time button on the display once to see the se-
lected baking time.
2 - Use ( ) or ( ) to alter the baking time.
3 - Press (OK) to set the desired baking time.
• Open or close the steam output valve manually
The steam output valve may be opened or closed by press-
ing the button.
If the LED of the button is turned off it means the valve is
closed. If the LED is on it means the valve is opened.
• Manual steam injection
The oven will inject steam automatically in the beginning of
the baking cycle (as mentioned previously). However, should
you need to inject more steam press the button once
and the control panel will inject steam.
If the operator realizes that baking time needs to be extend-
ed as the product is unloaded, he/she should close the oven
door within ten seconds and the oven will automatically add
minutes to the baking cycle.
Even when the oven is in standby mode in between baking
cycles, the turbines will continue functioning until the tem-
perature drops below 150ºC to allow the motors to cool
down.
If the changes are made in the programme 0---Manual, they
will be immediately stored in that programme.
If the changes are made in a different programme (not
0---Manual), they will only be effective for that baking cycle
and will not be stored in the programme for future baking
cycles.
Important note
Baking of products with high alcohol content is strongly
disadvised due to potential danger of explosion and fire.
If reduced alcohol content products are used, the steam
valve must remain open throughout baking in order to
easily evaporate alcohol content.

Notwithstanding the fulfilment of the aforementioned dead-
lines, the oven has a system that warns the operator of the need
to carry out periodic maintenance. This warning is a general
preventative warning. Therefore, the shorter term maintenance
tasks must be carried out regardless of there being a warning
signal.
This warning shows up with the message“SAT MAINTENANCE”
on the display. This message will be shown on the display as
long as the condition that triggered the warning persists.
After the maintenance process has been concluded, the warning
must be cancelled as it will reappear in a programmed manne
