To install a probe:

1. Attach the weight or anchor assembly to the end

of the probe. Insert the probe through the vessel’s

mounting connection, and feed the cable into the

vessel. Do not allow the probe to scrape against the

connection threads.

2. Secure the anchor assembly (if used), to the bottom of

the vessel.

3. Apply thread sealant to the mounting nut. Screw the

mounting nut into the mounting connection until tight.

4. Remove the Mylar housing insulator located over the

clamp. DO NOT DISCARD.

5. Loosen both socket head screws from the clamp. Pull the

clamp and Teflon® retaining bushing off of the probe.

6. While holding on to the probe cable, loosen the upper

packing gland nut. DO NOT ALLOW THE PROBE

CABLE TO FALL INTO THE VESSEL.

7. Pull the excess cable up through the packing gland nut

until the cable is taut. Tighten the packing gland nut.

8. Cut the cable 1.35" (34 mm) above the packing gland nut

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

9. Slide the Teflon® retaining bushing onto the cable and seat

it into the packing gland nut. Slide the clamp onto the

cable and seat it against the Teflon® retaining bushing.

10. Tighten both socket head screws, on the clamp, to approx-

imately 35 in/lbs of torque. Slip the Mylar® insulator over

the clamp.

Caution: Check probe terminal connection carefully to be certain

lug will not short to packing gland or interfere with assem-

bly of amplifier housing to probe.

11. Locate the white wire which is fastened to the probe

terminal (P), Connect the free end of this wire to the

probe connection screw.

12. Proceed to Section 1.7, Wiring.
