Safety notes for the user 

12 

3.3. Safety 

recommendations 

Follow the safety recommendations to prevent damage to persons or property. 
Further, the valid safety instructions for working places must be followed. 

 

 

 

  Only connect the unit to a power socket with earthing contact (PE – 

protective earth)! 

  The power supply plug serves as safe disconnecting device from the line 

and must be always easily accessible. 

  Operation is permitted with non-flammable liquids only. 

  Place the instrument on an even surface on a pad made of non-

inflammable material. 

  Do not stay in the area below the unit. 

  Make sure you read and understand all instructions and safety precautions 

listed in this manual before installing or operating your unit. 

  Never operate the unit without bath fluid in the bath. 

  Check the filling level of the bath fluid from time to time. Pump and heater 

must always be fully covered with the bath fluid! 

  The instrument is not suited for unsupervised continuous operation. 

  Do not drain the bath fluid while it is hot! 

Check the temperature of the bath fluid prior to draining (by switching the 
unit on for a short moment for example). 

  Observe the limited working temperature range when using plastic bath 

tanks. 

  Employ suitable connecting tubing. 

Make sure that the tubes are securely attached. 

  Never operate damaged or leaking equipment. 

  Always turn off the unit and disconnect the mains cable from the power 

source before performing any service or maintenance procedures, or 
before moving the unit. 

  Always empty the bath before moving the unit. 

  Never operate equipment with damaged mains power cables. 

 

 

  Some parts of the bath cover and the pump connections may become 

extremely warm during continuous operation. Therefore, exercise particular 
caution when touching these parts.
