5.1.3 Replacing Fan Filters
Nfinity’s intake fans contain filters that will need to
be replaced or cleaned periodically, depending on
the surrounding environment. Check by removing
the bottom bezel and noting the condition of the two
filters. If filters are dirty, replace them by removing
the plastic cover over the filter frame and inserting
a new filter in its place. Use caution when replacing
filters when fans are running.
The fan filters are washable and can be reused. To
wash filters, place them under running water (with
the dirt side down) to remove dirt and dust. Blot dry
with a towel and allow air-drying before reusing.
