Catalytic wallsThe walls with a catalytic coating are self-cleaning. They absorb fat which collects on wallswhile the oven operates.To support this self-cleaning process heat the oven without any food regularly:1. Open the oven door. The oven light turns on automatically.2. Remove all accessories from the oven.3. Close the door.4. Set an oven function.5. Set the oven temperature to 250 °C and let the oven operate for 1 hour.6. Clean the oven cavity with a soft and damp sponge.CAUTION!Do not attempt to clean catalytic surfaces with oven sprays, abrasive cleaners, soap or othercleaning agents. This may damage the catalytic surface.Discolouration of the catalytic surface has no effect on catalytic properties.Shelf Support RailsRemoving the shelf support rails1.
