lower part.
Danger of electrocution!
Isolate the appliance from the power supply before
changing the fuse.

14. Maintenance
The fan duct behind the air outlet grille should be checked
by a contractor every two years. Small dirt deposits can build
up here.
As part of regular maintenance, we recommend also checking the
control components. The safety and control components, and the
entire charge and discharge control system should be checked by
a contractor no more than ten years after commissioning.
