11. The ESM-01 sensor consists of an electrolyte reservoir assembly retained in the
sensor body by a threaded collar on the connector end of the sensor. Unscrew the
collar from the sensor body.

12. Grasp the connector and lift the electrolyte reservoir assembly out of the sensor body.
13. Turn the body upside down to remove the H
2
S scrubber. If it does not come out, push
on it from the top of the upside down body.
14. Discard the old H
2
S scrubber.
15. Carefully place the new H
2
S scrubber in the end of the sensor body. If the O-ring
came out, place it back in making sure it is seated in its groove.
16. Place the electrolyte reservoir assembly back in the sensor body making sure that the
ridges on the electrolyte reservoir assembly line up with the grooves inside the sensor
body.
CAUTION:
Verify that the electrolyte reservoir assembly is properly aligned before
inserting it into the sensor body. Forcing an electrolyte reservoir assembly
into its sensor body may damage the electrolyte reservoir assembly or the
sensor body.
17. Screw the collar of the ESM-01 sensor back on.
18. Plug the ESM-01 sensor back into the cable.
19. Insert the sensor into the ESM-01 flow chamber and push it in until it bottoms out.
20. Line up the holes in the ESM-01 sensor bracket with the two standoffs on the ESM-01
chamber.
21. Install the two sensor bracket screws.
22. 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, it may be
damaged when the top case is re-installed.
