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 glo-
ves (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. With the system "HP Designjet 9000s/10000s Air Purifier System" two filter elements are
placed behind each other in the filter unit. With the filter system "HP Designjet 9000s/10000s
Air Purification System" always replace both filter elements at the same time.
You should proceed as follows when replacing the filter:
