5.1.3Replacing 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.
