Information for Care and Maintenance of the Heating Plate with Technical
Enamel Coating
The technical enamel makes the heating plate easier to care fort and more
resistant to acids and bases. Because of it, however, the heating plate is also
more susceptible to extreme fluctuations in temperature and the force of
impact. This can result in cracks forming or the coating flaking off.
Make certain that the bottom of the placing vessel is even, clean and dry. The
bottom of the placing vessel must not have any sharp grooves, sides or edges.
We recommend most strongly that you clean the heating plate regularly.
