FISite Preparation and In Nation Instructions TLS-350 UST onitori stem Figure 36. Probe Assembly for Products NOT Requiring Water Measurement (4" Installation Kit) 16 CAUTION: WHEN SLIDING THE FLOAT ONTO THE PROBE SHAFT, BE CAREFUL NOT TO BREAK ANY OF THE MAGNET RETENTION FIN- GERS. THIS COULD RESULT IN IMPROPER MOVEMENT OF THE FLOAT AND INACCURATE READINGS. 6. Slide the boot onto the end of the probe, and turn until the boot's bosses snap into the probe detents. (Refer to Figure 34 or 35, or 36.) CAUTION: FAILURE TO SNAP THE BOOT INTO THE PROBE DETENTS COULD RESULT IN THE LOSS OF THE BOOT AND FLOATS WITHIN THE TANK. 8. Gently slide the floats to the bottom of the probe shaft. • Install each probe in an underground storage tank as follows (see Figure 37, "Magnetostrictive Probe Installa- tion Requirements"): lip .�, . •• 1 • 1. Turn OFF power to the TLS system. 2. Make sure any liquid other than the product to be dispensed has been pumped out of the tank. 3. Be sure there is no sludge in the bottom of the tank. Sludge can interfere with proper operation of the water float. CAUTION: HANDLE PROBES CAREFULLY! STRIKING OR DROPPING PROBE WILL RESULT IN LOSS OF CALIBRATION AND COULD CAUSE PERMANENT DAMAGE.

The extra probe height will be lodged in the riser pipe, which must be 6" longer than the minimum in order to provide room.) Figure 37. Magnetostrictive Probe Installation Require- ments for Underground Storage Tanks 4. Attach the probe cable connector to the mating plug on the top of the probe. Be sure the connector is attached securely by hand tightening the locking ring. 5. Place floats at bottom of probe before standing the probe on end. CAUTION: HANDLE PROBES CAREFULLY! STRIKING OR DROPPING PROBE WILL RESULT IN LOSS OF CALIBRATION AND COULD CAUSE PERMANENT DAMAGE. 6. Carefully lower probe into the riser pipe until the boot rests on the bottom of the tank. 16 CAUTION: DO NOT ALLOW PROBE TO FREEFALL AND/OR SHARPLY IMPACT THE BOTTOM OF THE TANK SHOCKTO THE PROBE FOOT WILL RESULT IN SEVERE PROBE DAM- AGE. 7. Feed the two -wire probe cable up through the riser pipe cap bushing and in through the junction box bushing. Leave enough slack in the cable between the cap and junction box to allow the cap to easily reach the riser pipe. In addition, leave enough slack under the riser cap to allow the probe to rest on the bottom of the tank. 8. Using wiring nuts, connect the wires from the probe cable to the probe field wires in the junction box (see Figure 38). Be sure to observe proper polarity between
