9.1 Cleaning
Interior and metal surfaces
Regular cleaning of the easy-to-clean bath prevents build up of material residues that
could impair the appearance and functionality of the stainless steel chamber over time.
The metal surfaces of the waterbath can be cleaned with normal stainless steel cleaning
agents. Make sure that no rusty objects come into contact with the interior or with the
stainless steel housing. Rust deposits can lead to an infection of the stainless steel. If rust
spots appear on the surface of the interior due to impurities, the affected area must be
immediately cleaned and polished.
Plastic parts
Do not clean plastic parts of the waterbath with caustic or solvent-based cleaning agents.
Glass surfaces
Glass surfaces can be cleaned with a commercially available glass cleaner.
9.2 Regular Maintenance
Once a year, grease the moving parts of the doors (hinges and lock) with thin silicone
grease and check that the hinge screws are not loose.
To guarantee perfect closed-loop control, we recommend calibrating the appliance once a
year (see }8.5Calibrate).
