  Make sure that the tubing is securely attached. 

  Regularly check the tubing for material defects (e.g., for cracks). 

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

before cleaning the unit. 

  Always empty the bath before moving the unit. 

  Transport the unit with care.  

  Sudden jolts or drops may cause damage in the interior of the unit. 

  Observe all warning labels. 

  Never remove warning labels. 

  Never operate equipment with damaged mains power cables. 

  Repairs are to be carried out only by qualified service personnel.

4. Installation 

 

  Place the unit on an even surface on a base made of 

nonflammable material. Using the castors (10a, 10b) move the unit 
to the intended location. 
For better stability, apply the holding breaks on the front casters 
(10a). 

  Cooling machine, pump motor and electronics produce intrinsic 

heat that is dissipated via the venting openings! Never cover these 
openings! 

  Do not set up the unit in the immediate vicinity of heat sources and 

do not expose to sun light. 

  Keep at least 20 cm of open space on the front and rear venting 

grid. 

  The place of installation should be large enough and provide 

sufficient air ventilation to ensure the room does not warm up 
excessively because of the heat the instrument rejects to the 
environment.  
For a fault (leakage) in the refrigeration system, the standard EN 
378 prescribes a certain room space to be available for each kg of 
refrigerant. 
> For 0.52 kg of refrigerant R-404A, 1 m3 of space is required.
