When <br />installing a riser pipe in a steel tank, codes may require a nonconductive <br />isolation -bushing be installed between the tank and riser pipe. <br />AWARNING It is the installer's responsibility to comply with all <br />applicable federal, state and local codes. Failure to do so may <br />create an Environmental Hazard. <br />* It is recommended that the bottom of the manhole be filled with <br />crushed stone to facilitate drainage when the TSP-ULS is installed in the <br />interstitial space of a steel tank. Do not cover the top of the riser with fill <br />material, it must remain accessible for service and for sensor installation. <br />Plan your conduit routing. Dig trenches as necessary to install rigid <br />threaded conduit (RMC) from each manhole junction box to the Intrinsically <br />Safe (I.S.) knockouts at the ATG console. The conduit may enter the <br />manhole either from its bottom or through its side. A junction box inside of <br />the building as a pull box to combine several sensor cables. If this is done, <br />then only one I.S. conduit knockout will be used. <br />1/2 OR 3/4 INCH <br />RIGID METAL <br />CONDUIT. <br />TO ATG <br />CONSOLE <br />SUMP/DISPENSER PAN <br />& COVER <br />WEATHERPROOF <br />JUNCTION C <br />BOX <br />EYS <br />(EPDXY <br />FILLED) <br />Y SEAL <br />FITTING <br />TSP-ULS <br />• • • O «* <br />0 f� <br />J v e v <br />Figure C Installation in Sunzps/Dispenser Pans <br />AWARNING Conduits must have EYS seal fittings installed in <br />accordance with NFPA 70 (National Electric Code) and NFPA <br />30A (Automotive and Marine Service Station Code). Failure to <br />seal conduits in accordance with NFPA 30A, and NFPA 70 could <br />allow flammable vapors to travel through the conduit in the ATG <br />console. An explosion could result causing serious injury, <br />property loss, or death. <br />You must install a weatherproof, electrical junction box inside each <br />manhole. The junction box should be installed high on the manhole wall to <br />prevent it from being submerged during heavy rains. <br />
