Operator responsibility – Safety instructions 

The products of JULABO ensure safe operation when installed, operated, and maintained 

according to common safety regulations. This section explains the potential dangers that may 

arise when operating the refrigerators for chemicals and also specifies the most important 

safety precautions to preclude these dangers as far as possible. 
 
The operator is responsible for the qualification of the personnel operating the units.  
The personnel operating the units should be regularly instructed about the dangers involved 

with their job activities as well as measures to avert these dangers. 
Make sure all persons tasked with operating, installing, and maintaining the unit have read 

and understand the safety information and operating instructions. 
When using hazardous materials or materials that could become hazardous, the refrigerators 

for chemicals may be operated only by persons who are absolutely familiar with these 

materials and the circulator. These persons must be fully aware of possible risks. 
 
If you have any questions concerning the operation of your unit or the information in this 

manual, please contact us!
