ionized) water.

Insert the internal body into the external body.
(Make sure that the O-ring is properly in place.)
4.
Return the spring to the top of the internal body.
5.
Hold the rubber sleeve in place by hand, then
twist the electrode protective cap 90º and fit the
rubber sleeve into the electrode protective cap.
6.
Maneuver the parts so that the "HORIBA" logo
faces the same direction as the reference
