Removing valve unit, collecting tank and condenser
Turn off the apparatus before beginning work.
The collecting tank and the Woulff-bottle should be checked
regularly for possible contents. If any substances have been
collected in these containers, they must be emptied. To do
this, the valve unit must be removed from its holder. The col-
lecting tank or Woulff-bottle can then be removed by twisting
it counterclockwise a quarter-turn. This is also a good oppor-
tunity to check the gasket for damage. The top of the housing
must be unscrewed if the condenser must be removed. The
condenser can then also be removed by turning it clockwise
a quarter-turn. However, the hoses must first be disconnected
from the condenser.
