1. Turn OFF AC power to the EMC system. 2. Remove the 4 -inch PVC cap from the monitoring well. 4.4 3. Drill (0.703" dia.) and tap a '/z x 14 NPT pipe thread through the top of the cap. 4. Thread the furnished cord grip into the cap. 5. Pass the sensor cable up through the cord grip from the inside of the cap until the sensor tip hangs at a point that is 12 inches above the highest level to which the water table normally rises. If this level is not known, position the sensor tip 12 inches above the bottom of the monitoring well or 12 inches above any water in the well. Tighten the cord grip to ensure a water -tight cable entry. NOTE: If the water table rises and immerses the sensor 11i causing a water alarm, loosen the cord grip and reposi- tion the sensor to hand (the higher of) 12 inches above the new water level or 12 inches above its previous position. 6. Measure the cable length required to reach the sensor junction box and trim the cable accordingly. 7. Install the furnished junction box cord grip in one of the threaded junction box access holes. 8. Pass the sensor cable through the cord grip into the junction box. Tighten the cord grip to ensure a water- tight seal at the cable entry. 9. Using wire nuts, connect the three sensor wires to field wires in the junction box (see Figure 42, "Three -Wire Vapor Sensor Field Wiring Diagram"). Be sure to observe color codes or wire markings to ensure proper polarity hookup to the Vapor Sensor Module connector in the EMC monitor. Figure 42. Three -Wire Vapor Sensor Field Wiring Diagrams. NOTE: SEAL WIRE NUT CONNECTIONS AT THIS "® TIME USING epoxy sealant, furnished with each sensor. WARNING: EPDXY SEALANT MAYBE IRRITATING TO EYES AND SKIN. MAY CAUSE SKIN SENSITI- ZATION IN SUSCEPTIBLE INDIVIDUALS. MAY BE ABSORBED THROUGH THE SKIN. EPDXY SEAL- ANT CONTAINS EPDXY RESIN AND VINYL CYCLO - HEXENE DIOXIDE. VINYL CYCLOHEXENE DIOX- IDE HAS CAUSED SKIN CANCER IN ANIMAL TESTS. PRECAUTIONS: AVOID EYE AND SKIN CONTACT. WEAR IMPERVIOUS GLOVES AND SAFETY GLAS- SES. USE ONLY IN WELL VENTILATED AREAS. 10.

(A new cap is supplied with the Gilbarco Groundwater Sensor.) 3. Lower the groundwater sensor into the monitoring well until the water float touches the bottom of the well. 4. Raise the sensor 1" to 2" from the bottom of the well and mark the sensor with a piece of tape at the point even with the top of the well casing. 5. Secure the sensor at the point marked with the tape to the retainer under the sensor well cap. Allow any excess sensor length (should be no more than 2') to hang loosely from the retainer. See Figure 43, "Groundwater Sensor Installation." 6. Press the sensor well cap into the top of the well with the excess sensor length hanging inside the well housing. 7. Pass the end of the three -wire sensor cable in through the cable bushing nut of the sensor junction box. I NOTE: The groundwater sensor comes equipped with "► a cable and plug-in connector. If the cable is not in- stalled on the sensor well cap, plug it into the mating connector on top of the cap and lock in position. 8. Using wiring nuts, connect the wires from the sensor cable to the sensor field wires in the junction box (see Figure 44, "Groundwater Sensor Field Wiring Diagram"). Be sure to observe proper polarity between the sensor and monitor wiring during installation. The conduit must be properly sealed in accordance with the National Elec- trical Code (NFPA 70) and the Automotive and Marine Service Station Code (NFPA 30A) since they pass from a Class I, Division I or Division II area into a non -hazardous area.
