7.5 Cleaning the heating bath
IMPORTANT
Risk of short circuit from fluid penetration into device
u
Do not immerse heating bath or rotary drive unit in water or pour water over them.
u Only wipe down the housing with a damp cloth.
The inside of the heating bath bowl should be cleaned regularly and at the latest if:
— the heating bath is contaminated
— limescale deposits start to form
— the stainless steel surface of the heating bath starts to rust
u Unplug the power supply for the heating bath and rotary drive unit.
u Allow the heating bath to cool down then empty it.

Use acetic acid to dissolve stubborn limescale deposits. Afterwards thoroughly
rinse out the bath.
