Cleaning 

 

Warning! 

 

Live parts in contact with cleaning agents 

Electric shock hazard 

 

Disconnect the device from the mains before cleaning.  

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. 

Notice

 

 

Live parts in contact with cleaning agents 

Property damage 

 

Disconnect the device from the mains before cleaning. 

 

Water and other liquids must not enter the control head. 

Only clean the control head with the cleaning agents, water (with washing-up liquid), petroleum benzine or ethanol.  
Do not use any acetone or aromatic hydrocarbons (dilution) This would lead to permanent damage to the plastic 
surfaces. 
Before all maintenance or cleaning work you must ensure that decontamination of the device is carried out if it has 
been in contact with hazardous materials.
