12.1 Cleaning: 
 

  Use a soft and damp cloth to clean the outside of the unit. 

  Only use mild cleaning agents to clean your air purifier. 

  Please make sure that water does not get inside the unit or the electric touch panel display at any time ! 

 
12.2 Storage: 
 

  We recommend covering the unit for storage or ideally packing it in its original box. 

  Store the unit in a dry and sufficiently ventilated place/space. 

 

 
13.) Other 
 

The air purifier has a so-called MEMORY function. This means that the unit retains the last settings made after an 
on/off. However, for safety reasons, this is not the case in the event of a power failure or if the mains plug is pulled 
out! 
 
The air purifier can be controlled and adjusted via the touch panel display as well as via the supplied remote 
control. 
A button cell CR2032 (3V) is required to operate the remote control. 

 
 
 

Notes on UV light: 

 

1.  The UV lamp normally has a service life of approx. 4,000 - 8,000 hours, depending on the on/off interval. 
2.  The wavelength is 254 nm. 
3.  The socket is T5 and the UV lamp has a 6 watt lead. 
4.  Replace the UV light only when the unit is switched off. 

 
 
 

Notes for the filters: 

 

1.  With an average use of approx. 8 hours daily, the filters last up to one year! In more polluted rooms, e.g. 

smokers' households, the filters may have to be replaced after approx. 4 - 6 months (see colour scale on the 
side of the HEPA/ULPA filter) ! 

2.  Change the HEPA/ULPA filter when it is dirty. 
3.  Never wash the fine filters.
