5. Cleaning, care and maintenance
WARNING
Risk to life through electrocution!
Before any cleaning and maintenance work, isolate the
appliance from the power supply.
To ensure correct operation of the appliance, the following
inspections and maintenance steps should be carried out.
The frequency with which maintenance work needs to be carried
out depends on the installation location, for example on the level
of dust.
5.1 Cleaning the appliance casing
Use a dry cloth to clean the outside of the appliance. If it is very
dirty, slightly moisten the cloth. Ensure that no moisture enters
the inside of the appliance. Never use scouring or cleaning agents.
5.2 Cleaning the fluff filter
5.2.1 Normal cleaning
To protect the heat exchanger against dirt, a fluff filter is integrated
behind the inlet grille. Dirty fluff filters restrict the air flow and
reduce the appliance efficiency.
For normal use, it is sufficient to check and, if necessary, clean
the fluff filter once a month.
