7. Pull the grey connecting tubes off of each end of the filter and remove it.
8. Install the new filter with the red RKI logo and part number on the inlet
side of the flow chamber, facing the front of the EAGLE 2. Make sure to
push the grey connection tubes all the way onto the filter’s hose barbs.
9. Confirm that the main PCB is seated in its slots and that its bottom edge
is resting on the bottom of the bottom case. If the main PCB is not seated
properly, then it may be damaged when the top case is re-installed.
10. Make sure that the top case gasket is fully seated in its groove and
carefully put the top case back on the bottom case. If you have any
difficulty mating the top and bottom cases, inspect the placement of the
main PCB and the placement of the top case gasket.
11. Turn the EAGLE 2 upside down and tighten the three case screws to
secure the top case to the bottom case.
