The side filter is sandwiched between the right outer panel of the projector and
the interior EMI shield that covers most components. It is installed vertically
near the perforated area of the right outer panel. Grasp the end of the filter and
pull it straight up to remove.
Insert the new side filter between the brackets, making sure that the tabbed side
faces out. Slide all the way down.

The top filter is installed horizontally near the center-right of the interior.
Standing at the left side of the projector, locate the edge of the filter just visible
under the small end of the funnel-like duct. Slide the filter towards the rear of the
projector as far as possible, exposing the entire filter. Lift out (Figure 4-7).
