Maintenance 

7.1  

Cleaning 

 

  Withdraw the mains plug before cleaning the unit! 

Cleaning can be carried out with water with a few drops of a surfactant (washing-up liquid) added and 
with the aid of a damp cloth. 

 

  No water should penetrate into the control section! 

 

  Carry out appropriate decontamination if dangerous material is spilt on or in the 

unit. 

  The cleaning or decontamination method is determined through the user's spe-

cialist knowledge. In case of doubt contact the manufacturer. 

7.2 

Servicing and repair 

 

  Withdraw the mains plug before all servicing and repair work! 

  Have repairs in the control section carried out only by specialists! 

LAUDA circulation heat exchangers need practically no servicing. If the temperature stabilising liquid in 
the laboratory circuit becomes contaminated, it should be renewed. 

 

 

Contaminated cooling liquid in the cooling circuit can lead to blockage of 
the heat exchanger, pump and bypass valve. 

The following safety fuses are located on the mains circuit board. If a fuse blows, re-
place it only by a fuse with the specified data: 

  Mains fuse F2 and F3 6.3A slow-blow (EEF 006) (

 mains indicator lamp no 

longer illuminates). 

  Low voltage fuse F1 0.2A quick-blow (EEF 002) (

 temperature display does 

not illuminate).
