9. EXTRAORDINARY MAINTENANCE
The oven may require extraordinary maintenance or replacement of
parts subject to wear such as seals, bulbs, and so on. The following
instructions describe how to carry out these minor maintenance
operations.
Before any intervention, disconnect the power supply of the device.
9.1 Replacement of light bulb
Remove the bulb protector A by turning anticlockwise and change bulb
B (in the 8-function model with front glass panel change the halogen
bulb C) with a similar one. Re-fit the bulb protector A.
Only use oven bulbs (T 300°C).
9.2 Oven door seal
To permit thorough cleaning of the oven, the seal
may be removed. Before removing the seal, take off
the door as described above. Once the door has
been taken off, lift the tabs at the corners as shown
in the figure.
After cleaning, refit the seal with the longer side
horizontal and insert the tabs into the appropriate
holes starting from the top ones.
