10.3 Removing the Vessel Top Plate and Accessories
All accessories must be removed for thorough cleaning of the indi-
vidual parts of the culture vessel. This is described in the following
sections. The cleaning itself is described in the chapter “Cleaning
and Storing Individual Parts”.
The cleaning of the hoses with pump heads, the basic unit, operat-
ing panel and the exit gas cooler are described in separate sec-
tions.
Sensors from third-party manufacturers are cleaned according to
their manufacturer’s specifications.

Unscrew the exit gas cooler from the vessel top plate port by
hand.

the exit gas filter and dispose of it.

gas cooler. (For details see the chapter “Cleaning the Exit Gas
