Replacing Fan Filters
Nfinity’s intake fans contain filters that will need
to be replaced / 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 a running
faucet (with the dirt side down) to remove dirt
and dust. Blot dry with a towel and allow air-
drying before reusing.
