B. INTERSTITIAL LIQUID SENSOR RISER PIPE IN- <br />STALLATION. <br />(See Figure 6, "Liquid Sensor Installation Requirements — <br />Steel Tanks" and Figure 7, "Liquid Sensor Installation <br />Requirements — Fiberglass Tanks"). <br />NOTE: If the tank is at a tilt, install the sensor at the <br />lower end of the tank. <br />1. Standard procedures for installing a fill pipe can be used. <br />Instructions are based on a 2 -inch riser pipe. <br />2. If the tank is buried, excavate the portion that contains <br />the riser hole. <br />3. Remove the bung from the hole and install the riser pipe. <br />1 NOTE: The top of the riser pipe must have a2 x 14 NPT <br />pipe thread or must accept a standard schedule 40 2 x <br />14 NPT male adaptor ring (supplied in Gilbarco Kit <br />Number Q12312-01). <br />Gilbarco Riser Cap Kit No. Q12312-01 can be used with <br />either a threaded or unthreaded riser pipe. <br />In addition, make sure there will be enough clearance <br />between the top of the installed riser cap and manhole <br />cover to allow room for the two -wire sensor cable to <br />protrude from the cap. <br />4. Install a standard adaptor ring and/or pipe cap on the <br />riser pipe. <br />.1 NOTE: If the threaded adaptor ring is used, install with <br />'I► the proper adhesive (i.e., TBC cement). Use thread <br />sealer, NOT ADHESIVE, when installing the riser cap. <br />Figure 6.

Select a mounting location on the inside wall of any <br />enclosed building. <br />a. Be sure the console will be protected from severe <br />vibration, extremes in temperature and humidity, rain, <br />and other conditions that could harm the equipment. <br />b. Consider the ease of routing power wiring conduit and <br />probe and sensor conduit to the monitor. <br />c. Be sure the mounting surface material is strong enough <br />to support the monitor's weight. <br />10" MINIMUM OIA <br />MANHOLE <br />2CORDGRIPSEALS <br />SUPPLIED WITH SENSOR <br />WEATHERPROOF <br />..
