4. Insert the displacer rod (key 64) into the vessel side of the sensor connection (key 65).
5. The pivot base must seat in the slots cast in the sensor connection. These slots will be horizontal when the sensor
connection (key 65) is oriented as shown in figure 3.
6. To reduce the possibility of nicking the O‐ring (key 77) on the pivot base, keep the displacer rod centered in the
sensor connection as much as possible while pushing the pivot base into the sensor connection. Be sure the pivot
base seats in the slots cast in the sensor connection.
7. Slide the spring (key 68) and spacer (key 66) onto the displacer rod and secure with the hex nut (key 67). Fully
tighten the hex nut (key 67).
8. View the sensor connection from the vessel side. Ensure that the pivot body arms remain aligned with the pivot
base arms (the two pivot body points are seated in the pivot base slots).
9. Install the sensor in the vessel.

and 44, not shown), away from the controller base (key 1).
3. Install the new relay using two relay mounting screws (key 33). To install it properly, you will need to shift it to the
right. Make certain that the relay mounting O‐rings (keys 43 and 44, not shown) are lubricated and completely in
their mounting bosses before installing the relay. Make certain the span lever assembly (key 6) is in line with and
pushing in on the end of the relay post (key 87).

(key 15).
3. Remove the O‐ring (key 16) and the old filter (key 15), and remove any debris from the filter boss.
4. Install a new supply filter, and O‐ring (key 16). Reinstall the filter cap (key 14), and tighten the filter cap screws
