Translation of original Operating Instructions, English, KNF 126291-126293 11/14 

1.  About this document 

 

1.1.  Using the Operating Instructions 

The Operating Instructions are an integral part of the rotary evapo-
rator. 

  Carefully read the Operating Instructions before bringing the 

rotary evaporator into operation. 

  Keep the Operating Instructions readily accessible at all times. 

  Pass on the Operating Instructions to the next owner. 

Rotary evaporators produced for specific customers (model desig-
nations prefixed with "PJ" or "PM") may exhibit differences from the 
Operating Instructions. 

  Whenever using custom rotary evaporators, also observe the 

agreed specifications. 

 

Compliance with the Operating Instructions is essential for safe 
and reliable operation of the rotary evaporator. Failure to 
observe the Operating Instructions may result in damage or 
injury. 

 

1.2.  Symbols and markings 

Warning 

 

WARNING 

 This symbol indicates a potential danger. 

 

It also indicates the possible consequences of failure 
to observe the warning. The signal word (e.g. "Warn-
ing") indicates the level of danger. 

 

  Here you will see actions for avoiding the danger 

and potential consequences.
