2. Install the transmitter housing using the bracket (supplied

by Magnetrol). Make sure to provide adequate clearance

to remove the housing cover. Refer to Figure 3 on page 3.

3. Remove the transmitter housing cover. Connect the posi-

tive lead of the interconnection cable to the (+) probe

terminal. Connect the negative lead and shield to the (–)

probe terminal. Refer to Figure 3 on page 3.

4. Proceed to Wiring, Section 1.6.

1.5.2 Flexible Probe

Caution: Flexible probes are shipped with the cable clamp and the

packing gland nut hand tightened to permit length adjust-

ment in the field. The cable clamp and packing gland nut

must be tightened before use. The end of a flexible probe

MUST be kept taut by attaching the anchor end at the

bottom of the vessel or by using a Magnetrol supplied

probe weight.

Caution: Do not discard the Mylar housing insulator.

Caution: The probe cable must not be in contact with any metallic

surface in its final installation position.

1. Attach the weight or anchor assembly to the end of the

probe. Insert the probe through the vessel’s mounting con-

nection 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. Refer to Figure 4.

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 inches (34mm) above the packing

gland nut and strip off 1.25 inches (32mm) 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.
