Cleaning and Maintenance
Cleaning

The housing and surfaces of the device can be cleaned using a damp cloth and, if
required, a mild soap solution.
Warning!
Risk of electric shock!
Liquids penetrating into the device could cause the device to become
live if it is still connected to the power supply.
Before cleaning the device:
▪ Switch the device off.
▪ Disconnect the power cord plug.
Caution:
Damage to the device
Liquids penetrating into the device could damage the electronics.
Only wipe the surfaces with a damp cloth and not a wet cloth.
Caution:
Damage to surfaces
The surfaces could be damaged by improper cleaning.
Do not use the following under any circumstances:
▪ Chlorine bleach or cleaning agents containing chlorine
▪ Substances containing solvents (e.g. acetone)
▪ Ammonia
▪ Abrasive cleaning agents such as cleaning wool, scouring agents or
Cleaning the heating bath
Rust spots on the bottom of the heating bath after shorter or longer use are caused by
the deposition of foreign substances (iron particles or rust particles).
Rust spots can be removed by cleaning with a commercial available
stainless steel polish.
Lime deposits can be removed easily by cleaning with a commercially
available lime solvent, e.g. on citric or acetic acid basis.
Please follow the instructions of the cleaning agent manufacturer.
Deposits of lime can lead to premature formation of rust as a result of
crevice corrosion.
We therefore recommend to clean the heating bath at regular intervals
with a stainless steel polish. At the same time, certain polishes can
hinder depositions of lime.
Cleaning of coated glassware sets
If the cleaning temperature is too high, the coating of the
glassware sets may be damaged.
Rinse coated glass parts only up to a maximum temperature of 50 °C.
