1. Acquire a mixer (part number WAT055847).
2. Remove the mounting screws and mixer clamps from the upper-left
corner of the chassis face.
3. Orient the mixer between the clamps as shown in configuration 1 of the
figure “1525 pump showing different mixer configurations (labeled 1, 2,
and 3)” on page 3-10 using hole pairs 1 and 3.
4. Firmly tighten the mounting screws.
5. Cut an appropriate length of 0.009-inch diameter tubing (part number
WAT026973 in the startup kit), and attach one end to the pressure
transducer outlet and the other end to the mixer inlet using a
compression screw and ferrule on each end.
6. Cut another length of 0.009-inch diameter tubing. Connect one end to
the mixer outlet and the other end to the reference valve inlet using a
