8. Maintenance and service
8.1 Cleaning
Warning!
Danger due to electric shock. Before doing any maintenance
work, pull out the mains plug.
Warning!
In case of appliances of a certain size, you can get accidentally
locked in, which is life-threatening. Do not climb into the appliance!
Caution!
Danger of cuts due to sharp edges. Always wear gloves when wor-
king in the chamber interior.
8.1.1 Working chamber and metal surfaces
Regular cleaning of the easy-to-clean working chamber prevents build up of material remains
that could impair the appearance and functionality of the stainless steel working chamber
over time.
The metal surfaces of the appliance 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, the affected
area must be immediately cleaned and polished.
8.1.2 Plastic parts
Do not clean the ControlCOCKPIT and other plastic parts of the appliance with caustic or
solvent-based cleaning agents.
8.1.3 Glass surfaces
Glass surfaces can be cleaned with a commercially available glass cleaner.
8.1.4 Peltier cooling module
In order to guarantee perfect
function and long lifetime of the
Peltier cooling modules, it is
absolutely essential that you
remove dust deposits from the
heat sink on the rear of the
appliance (with a vacuum
cleaner, paintbrush or bottle
brush, depending on the
amount).
To make cleaning easier, the
cover can be removed after the
screws have been loosened (Fig.
30).
