Fan/Air Filters
The recommended interval for cleaning the filters is every six months, but periodic checks and
cleaning should be done more often, if the system is in a dusty environment. The customer can
clean the filters.
➤ To clean and replace the filters
1. Remove the left-side fan filter (power supply filter):
a. Remove the filter tray enclosure from the lower left side of the system. The filter tray
enclosure snaps into rubber grommets and can be removed without tools (Figure 8-1).
b. Remove the filter from the filter tray.
2. Open the rear cover door and pull out the rear air filter (Figure 8-2).
3. Vacuum both filters and then clean them with soap and water.
