Maintenance and cleaning
7.4.1 Before starting the automatic cleaning cycle
The Pyrolysis process can be performed at any time of the day or night
(to take advantage of lower night-time electricity rates).
Before proceeding, check the following:
47
• The baking sheet, the oven dish and the roof liner only can be left
inside the oven, since they withstand the high temperatures of the
pyrolysis process; all the other accessories must be taken out of the
oven;
• remove the most obvious traces of dirt (Pyrolysis cleaning would take
too long);
• make sure the oven door is properly closed;
• when setting the cleaning cycle, remember the following:
NOT VERY DIRTY DIRTY VERY DIRTY
DURATION OF
CLEANING :
90 MIN. 105 MIN. 120 MIN.
NOTE:
THE FIRST AUTOMATIC CLEANING CYCLE COULD CAUSE BAD SMELLS DUE
TO EVAPORATION OF OILY SUBSTANCES USED DURING MANUFACTURE.
THIS IS A QUITE NORMAL OCCURRENCE WHICH DISAPPEARS AFTER THE
FIRST CLEANING CYCLE.
DURING THE AUTOMATIC CLEANING CYCLE, THE FANS MAKE MORE NOISE
DUE TO GREATER ROTATION SPEED. THIS IS QUITE NORMAL AND IS
INTENDED TO FAVOUR THE ELIMINATION OF HEAT. AFTER PYROLYSIS,
VENTILATION CONTINUES AUTOMATICALLY FOR LONG ENOUGH TO PREVENT
THE CABINET WALLS AND FRONT OF THE OVEN FROM OVERHEATING.
7.4.2 How the automatic cleaning cycle works
The following table shows an example of automatic cleaning cycle
operation.
When the cleaning cycle is set, the thermostat light comes on, while the
door lock device (and indicator light) is not engaged.
When the temperature reaches 300 °C, a lock device triggers to prevent
door opening.
At the end of the cleaning cycle, the thermostat indicator light goes off.
The door-lock is only released afterwards when the temperature inside
the oven has dropped below 300 °C.
