30– Press the – or + key to change the duration of thepyrolysis. You can choose between the followingtimes: 02:00, 02:30 and 3:00.– Press the (Confirm) key to start pyrolysis. Anaudible signal is sounded.– For your safety, the oven door is lockedimmediately. The locking and unlocking processtakes about 30 seconds. The (door lock)symbol lights up during this time. The ovenlighting goes off. On the display, the (doorlock), (cooking time) and (pyrolysis)symbols light up.Do not try to open the oven door during the self-cleaning process.Note: during the pyrolysis process, it is notpossible to query the temperature value nor thetime.End of pyrolysis:After the pyrolysis process has ended, an audiblesignal sounds and the (cooking time) symbolflashes. Press any key and turn the “Temperature"control knob to the 0 position and the “Mode" knobto a position other than Pyrolysis.Please note that, for safety reasons, the door will notbe unlocked until until the oven has cooled down to150 °C. The door lock symbol goes off.Wait until the oven has cooled down; then, you canremove any pyrolysis residues (e.g. ash) from theoven compartment.Ending the pyrolysis process before expiry ofthe entered time:– Turn the “Temperature" control knob to the 0position and the “Mode" control knob to a positionother than Pyrolysis.– Pay attention to the fact that the door is notunlocked until at a temperature of 150 °C or less.Tip: wait until the appliance indicates that thepyrolysis process has ended. This ensures that youwill achieve an optimum cleaning result.Starting pyrolysis at a later time:– Enter the required switch-off time (seeChapter 3).– Turn the control knobs to the pyrolysis setting asdescribed above.Note: you can query the current pyrolysis time bypressing the (Timer) key. You can increase thelength of the pyrolytic cleaning process duringoperation. Press the + key to increase the valueby 30 minutes in each case. Confirm the value bypressing the (confirmation) key.In this mode of operation (auto pyrolysis), evenstubborn soiling is burnt away at temperaturesaround 485 °C.After the pyrolytic cleaning process, you canremove the ash easily from the oven using a moistcloth.
