NOTE: Do not allow the probe to fall in the tank while performing

steps 7 through 18.

7. Loosen both socket head clamp screws.

8. Pull clamp and Teflon® retaining bushing off probe.

9. While holding the probe cable, loosen upper probe nut.

10. Pull excess cable up, through the probe nuts, until cable

is taut.

11. Tighten the probe nuts.

12. Cut off cable 1.35" (34 mm) above top of upper probe

nut, and strip off 1.25" (32 mm) of insulation.

13. Slide Teflon retaining bushing onto cable, and seat it into

the upper probe nut.

14. Slide clamp onto cable and seat it in the Teflon retaining

bushing.

15. Tighten both socket head clamp screws to approximately

35 inches/pound torque.

16. Slip mylar housing insulator over clamp.

17. Screw housing onto probe and tighten. Make sure conduit

connection is properly aligned for wire entry.

18. Remove housing cover.

NOTE: Refer to Electrostatic Discharge Handling Procedure on

page 9.

19. Remove the electronics assembly from the housing by

loosening the four mounting screws.

20. Locate the white wire, which is connected to the probe

terminal (P) on the circuit board, and connect its free end

to the probe connection screw.

21. Reinstall the electronics assembly into the housing.

Caution: Check probe terminal connection carefully to ensure that

the lug will not short packing gland or interfere with

assembly of amplifier housing to probe.

22. Proceed to Wiring section on page 9.
