MOUNTING PROCEDURE cont.
Flexible Probe cont.
CAUTION: Flexible probes are shipped with the cable
clamp and the probe nut hand tightened. The end of
a flexible probe MUST be secured to the bottom of the
tank by either attachment to a bracket or to a heavy
weight in order to keep the probe taut. Follow the
mounting instructions listed below.
1. Remove mylar housing insulator located over the clamp.
2. Attach weight (if used) to probe end.
CAUTION: Do not discard the mylar housing
insulator.
CAUTION: Check probe terminal connection careful-
ly to be certain lug will not short to packing gland or
interfere with assembly of remote housing to probe.
17. Screw housing onto probe and tighten. Make sure con-
duit connection is properly aligned for wire entry. Refer to
Figure 5.
18. Locate the white wire on the upper printed circuit board.
Connect the free end of this wire to the probe connection
screw. Refer to Figure 5.
19. Proceed to Wiring Procedure on Page 5.
3. Insert probe end through tank mounting bushing and
feed cable into the tank. Do not allow probe insulation to
be damaged by scraping against the bushing threads.
4. Secure lower end of probe (or optional weight) to tank
bracket if one is used.
CAUTION: Probe cable must not be in contact with
anything metallic in its final installation position.
5. Apply thread sealant to mounting nut.
6. Screw mounting nut into tank bushing until tight.
NOTE: Do not allow the probe to fall in the tank while
following steps 7 through 18.
Apply Wrench
Here
CAUTION: Apply wrench to lower probe nut only.
7. Loosen both socket clamp screws.
8. Pull clamp and teflon retaining bushing off probe.
9. While holding probe cable, loosen upper probe nut.
10. Pull excess cable up through probe nuts until cable is taut.
11. Tighten the probe nuts.
12. Cut off cable 1.35 inches (34 mm) above top of upper
probe nut and strip off 1.25 inches (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 in./lbs. torque.
16. Slip mylar housing insulator over clamp.
NOTE: Do not allow the probe to fall in the tank while
following steps 7 through 18.
