Note The green LED blinks after an interval period of 700 operating hours as an indication to order new filters, and also this means the filter elements must be replaced within 100 additional operating hours. Caution! When removing or inserting the filter elements it is recommended to use protective gloves (disposable gloves made of polyethylene, latex or Nitrile®) before carrying out the filters replacement and/or the suction hoses. With the system "HP Designjet 8000s Air Purifier System" one filter element is used in the filter unit.
