8.1.8 

Refrigeration system 

 

 

DANGER 

Risk of explosion due to refrigerants (natural, flammable 
refrigerants) 

The natural refrigerants used are highly flammable and can form an 
explosive mixture if their concentration in the ambient air is sufficiently 
high. 

There is an explosion hazard. 
•  Work on the refrigeration system of the freeze-dryer must only be 

carried out by qualified specialist personnel who have been trained to 
handle flammable refrigerants! 

•  Ensure good ventilation and make sure that no ignition sources (e.g. 

soldering iron, welding equipment) are present! 

 

 

 

WARNING 

Risk of cold burns or frostbite caused by the refrigerant 

When work is performed on the refrigeration system of the freeze-dryer, 
refrigerant may escape in the liquid or gas state and under high pressure. 

In the case of skin contact with liquid refrigerant, cold burns or frostbite 
may result. 
•  Only qualified persons are authorised to perform work on the 

refrigeration system of the freeze-dryer! 

 

 

WARNING 

Risk of poisoning caused by the refrigerant (non-flammable 
refrigerants) 

During its decomposition (e.g. due to naked flames or hot surfaces), 
hazardous/toxic gases are released. 

Contact with the decomposition products may cause severe damage to 
health. 
•  Only qualified persons are authorised to perform work on the 

refrigeration system of the freeze-dryer! 

•  Do not eat, drink, or smoke when working on the refrigeration system! 

 

 

 

 

The refrigerant circuit is a closed system. Only certified and qualified 
persons are authorised to perform work on the refrigeration system! 

 

 

 

 

8.1.9 

 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.
