Cleaning, Care And Maintenance; Malfunction, Possible Defects - SCHOTT Instruments SLK 1 Gebrauchsanleitung

5 Cleaning, care, and maintenance
The glass-ceramics material is largely chemically resistant, the heating zone remains plane at all times, is
free of pores and therefore easy to clean. If the heating zone is slightly dirty, you should at best clean it
simply using warm water and a few drops of a household washing-up liquid as long as the heating zone is
lukewarm or cold.
To remove crust, lime, and water marks or stains with a metallic shine you should use a household deter-
gent for ovens with glass-ceramics boiling zones. Please use a wet cloth or sponge to remove the deter-
gent residues as well, since some of the commercially available detergents adopt an etching effect at
higher temperatures. If soiling has already turned into a crust, you should use a razor-blade scraper. Plas-
tic objects and aluminium foil as well as sugar-containing substances reaching the hot surface are to
be lifted off immediately using the razor-blade scraper.

Malfunction, possible defects

Malfunction / defect
The Laboratory hot plates
does not switch on;
heating zone does not heat up
No display
Impossibility of switching the
Laboratory hot plates off
In the case of the SLK 6 no
display of the temperature,
but
Never use abrasive cleaners! In most cases it will suffice after each use to
clean the plates using a moist cloth and some household washing-up liquid.
Subsequently rub dry.
Crusts and food boiled over should at best be first soaked with a wet cloth.
Subsequently, use a glass scraper to remove the residues.
Note:
Sugar and melted plastics should be removed immediately when the heating
zone is still hot.
Cause
