15.11.2 Cleaning The Air Filters
1 The filters are in the fan guards, which are held in place by four plastic clips,
see Figure 15-60. Pry two adjacent clips free with finger-tips and slide the filter
free.
2 Wash the two filters in soapy water, and rinse them, shaking off the rinse water.
3 Examine the blades of the fan. If they are dirty, wipe them clean or blow the dust
off with compressed air.
4 Replace the filters, being sure that the clips are all engaged. The orientation
does not matter.

15.11.3 Closing The Service Module
1 Replace the plastic cover of the Service Module, by pivoting the cover back into
place.
NOTE: Check the cable connection to the printed circuit board to be sure the
connection has not loosened.
NOTE: The brackets holding the electrical and pneumatic connections may
impede the placement of the plastic cover. The cover has small ledges
which go inside the brackets. As the cover drops down, however, the
brackets may need to be pressed against the ledges.
2 When the cover is fully in place, the four aluminum legs will be in view through
the screw holes. If any of the legs are not touching the inside of the plastic,
check all around the joint between the plastic cover and the cast aluminum
base plate to find out why the cover is not correctly seated. Once the cover is
correctly seated, replace the four screws with their rubber feet. Tighten the
screws securely. Pick up the Service Module and invert to normal position. The
Service Module is now ready to be put back in service.
