MAINTENANCE

Replacing Fan Filters

(Transformer Models Only)
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.
