Natural refrigerants are flammable! 

The device contains flammable refrigerants. If there is a leak in the refrigerant 
cycle, a flammable concentration may form in the air and ignite or explode. This 
can result in serious injury or death. 
•  Use the required minimum room size for operating the device. 
•  Do not store any potential sources of ignition near the device. 
•  If refrigerant leaks, stop the device immediately and ventilate the room 

thoroughly. 

•  Have damage to the refrigerant cycle repaired only by JULABO service 

technicians or qualified specialists. 

•  Have maintenance work performed only by JULABO service technicians or 

qualified specialists. 

 

 

Wear personal protective equipment! 

Lacking or unsuitable personal protective equipment increases the risk of health 
damage and injury. 
Personal protective equipment includes, for example: 
–  Work gloves 
–  Safety shoes 
-  Protective clothing 
–  Breathing protection 
-  Hearing protection 
–  Face and eye protection 
•  Specify and provide personal protective equipment for the respective 

application. 

•  Use only personal protective equipment that is in good condition and 

provides effective protection. 

•  Adapt personal protective equipment to the person, e.g., by size. 
 

 

Keep safety symbols legible! 

Safety symbols on the unit warn of dangers in hazardous areas and are an 
important part of the unit’s safety equipment. Missing safety symbols increase 
the risk of injury to persons. 
•  Clean dirty safety symbols. 
•  Replace damaged and unrecognizable safety symbols immediately.
