8.4 Replacing the glass pane
FDM221
The glass pane is provided with a number. It is covered by a foil layer. This foil
holds the glass splinters together when the glass pane is pushed in, enabling
trouble-free removal of the glass.
Proceed as follows:
1. Press the two key knobs in the recesses.
2. Pull the lid forwards.
3. Insert the glass pane so that the number is pointing to the bottom and can be
read from the front.
4. Insert the glass on the guiding (1) and push it towards the alarm actuator (2).
5. Push the retainer (3) to the right until the glass is below the retainer.
6. Close the housing with the lid.
