Filters Replacement  

 

Dif-Pur models have a visual indicator of dirty filter alarm. When 
the LED lights up, the two filters need to be changed. 
 
Even if the dirty filter signal is not turned on, it is highly 
recommended to replace the filters every 500 hours in the case of 
the G4 and every 3,000 hours for the HEPA filter. 
 
For the replacement of the absolute filter, the inlet grille must first 
be removed and then the four wing nuts that press the filter 
loosen. 
Finally, remove the dirty filter and place the new one by following 
the steps in reverse order. 
In the case of the prefilter it is not necessary to remove the inlet grille since the filter is located on top of the 
equipment. Just loosen the two wing nuts that keep it fixed to the equipment and remove the dirty filter. 
 
To assemble, place the filter clean and tighten the wing nuts to prevent it from moving or entering air without 
passing through the filter. 
 

  

  

 

   

   

 

 

   

 

Fans Replacement  

 
Before  changing  any  fan  or  fans,  it  is  mandatory  to  advise  and  indicate  that  work  is  under  way  on  the 
equipment, disconnect the power from the current and make sure that there is no voltage and that the fans 
have stopped.
