supply before maintenance work. Always observe the
safety instructions!

Allow the appliance to cool down before removing it.
7.2 Maintenance and cleaning by the user
The switching power supply is low-maintenance due to the
components used. However, it is advisable to check the dust
accumulation inside the device from time to time. If there is a lot of
dust, the device should be blown out with dry compressed air in order
to prevent a reduction in cooling and thus a reduction in service life.
