In the case of an error, the first two digits of the display show ER, followed by
the error number. Refer to the chapter on errors for more information.
It is possible to change the operating parameters of the furnace. In the
parameter edit menu, the central display shows a P, followed by the parameter
number. The two digits on the right show the value of the parameter. Refer to
the chapter on the configuration menu for more information.
Table 2: Description of messages on the central screen.
2.1.1 Switching on the equipment
The equipment is switched on or off by pressing the START/STOP button for two
seconds.
In order to protect the furnace from possible overheating, some protective
elements may work even when the furnace is switched off. When the oven is at
a safe temperature it will automatically turn off.
If the equipment does not turn on, check the status of the safety thermostat and the
service switch, located at the rear of the equipment.

2.1.2 Cooking modes
There are three cooking modes: convection, mixed and steam. To select a particular
mode, tap on the corresponding button.
Figure 5: Cooking mode selector.
The convection mode acts as a forced convection oven without adding or removing
moisture from the baking chamber.
The mixed convection mode allows to regulate, in an intelligent and controlled way by
the oven, the elimination or contribution of humidity in the cooking chamber. To do this,
press the humidity button and adjust with the +/- buttons to the desired value. This value
is shown in the central indicator.

Table 3: Cooking modes in Mychef ovens
In order to prolong the life of your oven, it may automatically reduce the
maximum temperature of the baking chamber.
In all cooking modes it is possible to humidify the chamber at will. To do so, press the
HUMIDITY button until the oven sprays water into the baking chamber.
2.1.3 Cooking control
2.1.3.1 Temperature and time controlled cooking
In the temperature and time control mode we choose a cooking mode, a temperature
and a time by adjusting with the +/- buttons after having pressed the TEMPERATURE and
TIME buttons respectively.

11
By pressing the START/STOP button, the oven will start to heat the chamber and will
stop when the set time has passed. At this point, the time indicator will display the
keyword "End", the oven will beep for one second and the interior light will illuminate until
the user finishes cooking by lightly pressing the START/STOP button.
Example of cooking at 90º for 10 minutes:
Figure 7: Example. Cooking at 90ºC in steam mode for 10 minutes.
Figure 8: Oven temperature.
2.1.4 Start of the cooking cycle
Once the firing parameters have been selected, either in manual mode or in a certain
program, the process can be started.
To do this, press the START/STOP key slightly. The two central points will flash every
second.

2.1.5 End of cycle
At the end of a cooking cycle, the unit signals this status visually and acoustically.
Specifically:
- A beep is emitted.
- The light in the oven chamber comes on.
- The keyword END appears in the central display until the user finishes the firing.
Press START/STOP to end the cooking process.
2.1.6 Speed selection
In any cooking mode the user can select the speed of the convection fan that best suits
his needs. To do this, press the fan speed button. Then select the appropriate speed with
the +/- buttons.

2.1.7 Automatic cleaning
2.1.7.1 Self-cleaning and rinsing program
Using the MyCare cleaning system allows for automatic cleaning of the firing chamber
and has a washing program specifically designed to use CleanDuo detergent. The
special formulation of this product stands out for having twice the concentration of
active product than most similar products available on the market. It also includes a
polishing additive for a perfect all-in-one finish. This allows you to use only one CleanDuo
tablet per wash, with the consequent savings and ease of use.
Use CleanDuo in the Cook and Bake ovens, both equipped with the automatic
washing system. The use of other products will void the warranty.
For the use of the cleaning processes and for the handling of the products used
in the process, appropriate protections should be used. Never touch the
detergent with your hands.
The time required to perform the self-cleaning program is listed in the table below:
Program
Description
Duration

ECO self-cleaning program
70
minutes
Table 4: Self-cleaning and rinsing program.
Before starting any cleaning process, make sure that the water passage to the
equipment is open.
Prior to the self-cleaning cycle, remove any solid food pieces/rests from the chamber by
hand. Do not use the hand shower accessory to remove food residues from the cooking
chamber, remove them first and prevent them from going down the drain. No trays or

14
grids should be placed during the washing process. It should always be done without
load, to ensure that the equipment is properly cleaned.
The automatic cleaning cycle can then be started. To do this, select the cleaning program
on the control panel by pressing the CLEAN button. The cleaning program appears on
the central display.
Figure 12: Self-cleaning program.
2.1.7.2 Fast cooling
Before placing the CleanDuo tablet, check that the temperature of the cooking chamber
is not too high. If the furnace is too hot, the central display will show that cooling is
required.
Figure 13: Required temperature setting.
In this mode the convection fan is turned on and the resistors are turned off. In this
particular case, even if the oven door is opened the process will not stop and the fan will
continue to rotate. In this way, and with the door open, the temperature of the chamber
can be lowered in a few seconds.
Once in this mode, the display alternately shows the temperature of the cooking
chamber. To exit the fast cooling mode, briefly press START/STOP.
Please note that in this mode the convection fan works with the door open. Take
the appropriate precautions.
Once the oven is at a low enough temperature, it will show that you can cancel the
cooling process:

15
Figure 14: Cooling completed.
At this point it is important to stop the fan using the START/STOP button, open the door
and insert the detergent tablet into the dedicated housing. Once entered, close the door
again to start the cleaning program.
Never place the detergent with the convection fan running.
If cooling is not required, you can place the MyCare detergent directly in its allocated
space, and start the cleaning or rinsing cycle by pressing the START/STOP key. Place as
many tablets as there are holes in your oven.
Figure 15: MyCare detergent holder.

16
Before starting any cleaning process, check that no temperature adjustment of
the firing chamber is required.
To introduce the detergent tablet into the chamber it is essential to stop the
fan. It is important not to introduce the detergent while it is in operation in
order to prevent the detergent from being dragged away by the air current
which could endanger the health of the user.
Once the automatic washing process has started, do not open the door under any
circumstances, as chemicals used for cleaning may escape and come out as steam.
This situation would entail a significant risk of corrosion and burns.
Never open the oven door during an automatic cleaning process.
The process can be stopped in an emergency with the START/STOP button.
If the cleaning process has been stopped without automatic completion, it is
mandatory to remove all undissolved detergent tablet pieces from the chamber
before proceeding with the final rinse.
If, at the end of any of the automatic cleaning processes, you find that there are still
traces of detergent in the chamber (even behind the fan protection plate), run a self-
cleaning program without detergent again or carry out a thorough manual rinse of the
cooking chamber.
If there is a power failure during the cleaning process, the furnace will resume the
cleaning process from the beginning.

2.2 Configuration menu
To access the configuration menu, with the furnace turned off, press the CONVECTION
and START/STOP buttons simultaneously.
Figure 16: Accessing the configuration menu.
When entering the configuration menu, the three mode indicators, convection, mixed and
steam, will light up simultaneously.
To navigate through the parameters, press the CONVECTION button and adjust the
parameter number with the +/- buttons.
Once the parameter is selected, to edit it press the STEAM button and adjust the
parameter value with the +/- buttons.

The parameters provide information on a very wide range of characteristics, from the
type of furnace to the configuration of the fan, etc. and also allow the technical service
to carry out tests and trials to ensure perfect operation.
2.2.1.1 NightWatch
NightWatch allows the oven to automatically continue a cooking process after a power
failure. This functionality is especially useful for unattended cooking.
This function will only continue with one firing in the event of a power failure and
subsequent recovery of the power supply.
This function can be disabled by your dealer. Make sure that you fully understand
the risks of its use.
When a power failure and subsequent restoration of the power supply occur, the furnace
recovers the firing in progress (if any) and continues it with the same parameters as
before the power failure.
In the event of a power failure during a wash, the oven starts the self-cleaning process
from scratch.

2.3 Errors and alarms
Errors and alarms can occur during the preparation and execution of cooking or washing
processes. If this is the case, the central display will show the error or alarm code.
