Ll 1 WARNING: TO PROTECT YOURSELF AND OTHERS FROM BEING STRUCK BY VEHICLES DURING WORK, BLOCK OFF YOUR WORK AREA DURING INSTALLATION AND SERVICE. .111 WARNING: TO AVOID ELECTRICAL SHOCK WHICH COULD KILL YOU, BE SURE AC POWER TO THE EMC MONITOR IS OFF DURING INSTALLATION. A. TANK DIAMETER MEASUREMENT. Perform the following procedure to ensure that probes are installed in the proper tanks (see Figure 18, "Tank Diameter Measurement"). Inaccurate readings will result if probes are not the correct length for the given tank diameter. 1. Measure the distance from the bottom of the tank to the top of the probe riser pipe (a). 2. Measure the distance from the bottom of the probe riser pipe to the top of the probe riser pipe (b). 3. Subtract (b) from (a) to determine the correct tank diameter (c). 4. Make sure the probe length (Dimension "A", Figure 19, "Capacitance Probe Dimensions" is correct for the tank diameter. PROBE RISER PIPE TANK Clb a-b=c Figure 18. Tank Diameter Measurement. Figure 19. Capacitance Probe Dimensions. Site Prepara n and Installation Instructions EMC UST Monitoring System The riser pipe cap must have 3/8" tapped hole for passage of probe wires. Cap kits with pre -drilled holes for a standard 4" riser pipe area available from Gilbarco. Order Kit Number Q12598-05, one for each probe. If a kit has not been ordered, perform the following: I WARNING: DO NOT PERFORM DRILLING AND TAPPING PROCEDURES IN A HAZARDOUS AREA. DRILLING AND TAPPING CAN CAUSE SPARKS AND IGNITE VOLATILE FUMES AND LIQUIDS FOUND IN A CLASS I, GROUP D HAZARDOUS LO- CATION. FAILURE TO COMPLY COULD RESULT IN DEATH, SERIOUS PERSONAL INJURY, PROPERTY LOSS AND EQUIPMENT DAMAGE. 1. Use a standard 4" tank locking cap, "Evertite" or equiva- lent, with standard ring adaptor. 2. Drill and tap the cap for a3/8 x 18 NPT cord grip thread (see Figure 20, "Probe Riser Cap Modification"). 3. Install a water -tight cable bushing in the 3/a" threaded hole in the top of the cap. Use an appropriate thread sealant to ensure water -tightness. Also install a water -tight cable bushing in the probe junction box in a similar manner. Figure 20.
