9.6.2 Vessel Top Plate
CAUTION!
Danger of damaging the vessel top plate or its
component parts and sensors!
Individual component parts of the vessel top plate
are very sensitive to force effects. Component
parts may be damaged by negligent or inappropri-
ate cleaning.
Therefore:
– Carefully handle component parts of the vessel
top plate, especially the stirrer shaft and the ce-
ramic bottom bearings.
– Always clean component parts of the vessel top
plate manually. The vessel top plate must not
be cleaned in a washing machine.
NOTICE!
Handling of the vessel top plate and its component
parts is described in detail in the subchapter "Pre-
paring the vessel" of the main chapter "Prepara-
tions for Use". Furthermore, these single steps are
not repeatedly described.
