8.1 Cleaning
Warning!
Danger of injury by electric shock. Before any cleaning work, pull
out the mains plug.
8.1.1 Interior and metal surfaces
Regular cleaning of the easy-to-clean interior prevents
build-up of material remains that could impair the
appearance and functionality of the stainless steel
chamber over time.
To clean the interior, the fan cover can be removed by
pulling it slightly forwards after the two fixing screws
have been screwed out ( Fig. 31 ). The metal surfaces of
the chamber can be cleaned with normal stainless steel
cleaning agents.
Make sure that no rusty objects come into contact with
the working chamber or with the stainless steel housing.
Rust deposits can lead to an infection of the stainless
steel. If rust spots should appear on the surface of the
working chamber due to impurities, immediately clean
and polish the affected area.
8.1.2 Plastic parts
Do not clean the operating panel, the plastic input module and other plastic parts of the ap-
pliance with caustic or solvent-based cleaning agents.
8.1.3 Peltier module
In order to guarantee perfect function and long lifetime
of the Peltier dehumidification modules on the rear side
of the appliance, it is absolutely essential to remove dust
deposits from the heat sink (with a vacuum cleaner,
paintbrush or bottle brush, depending on the amount).
To make cleaning easier, the protective cover can be
removed after the screws have been loosened ( Fig. 32 ).
