8.1.4 Vacuum sensor
NOTE
Please refer to the separate operating manual of the vacuum sensor!
The vacuum sensor has only a limited service life. Especially carbon-
containing substances, e.g. alcoholic compounds, reduce the service life
extremely.
• The vacuum sensor is maintenance-free.
• Remove any soiling on the outside with a cloth.

8.1.5 Accessories
CAUTION
For the care of the accessories, special safety measures must be
considered as these are measures that will ensure operational safety at
the same time.
Chemical reactions as well as stress-corrosion (combination of oscillating
pressure and chemical reaction) can affect or destroy the metal and plastic
parts. Barely detectable cracks on the surface can expand and weaken the
material without any visible signs.
• Check the material regularly (at least once a month) for
– cracks
– visible damage of the surface
– pressure marks
– signs of corrosion
– other changes.
• Replace any damaged components immediately for your own safety.
• Immediately rinse off the accessories if any liquids that may cause
corrosion come into contact with them.
• Clean the accessories outside the freeze-dryer once a week or
preferably after each use.
