8.4 Maintaining the Fan Filter
The back of the system includes two 120-millimeter (4-3/4 inch) fans, which suck in ambient air through a filter element and maintain a slightly positive pressure inside the housing. While the system is running, filtered air comes in contact with the electronics.
The fan filters should be inspected weekly for cleanliness. If found dirty, they can be washed in hot water or be replaced.
• To inspect each filter, pry off the fan bezel with a flat-blade screwdriver and remove the filter, which is held by the bezel.
• To reinstall the filter, reseat it in the bezel and press the bezel back in place. Fan filters and the fan itself are user-replaceable items.
Fan filters are readily available from electronics distributors and computer stores. When purchasing a new fan, ensure that its voltage is the same as the voltage marked on the old fan.
