To access the system check valves:

Fig. 13.3. Location of the inlet (bottom) and outlet (top) check valves on the pump assembly.
Note: The inlet and outlet check valves look similar, but they are different parts. Assembly
and disassembly procedures for the valves are not identical; be sure to return them to their
correct locations (inlet valves on the bottom and outlet valves on the top). The instrument
will not operate properly if the check valves are replaced in the incorrect positions.
