Introduction <br /> These instructions describe the installation of Veeder-Root Vacuum sensors in a STP containment sump to monitor <br /> the interstitial space of: <br /> • Double-wall product lines <br /> • Double-wall vapor return lines <br /> • Double-wall tank vent lines <br /> • Double-wall tanks* <br /> • Double-wall containment sumps <br /> *NOTE: Double-walled tanks must provide access for installation of a liquid sensor at the lowest point of the <br /> interstice. <br /> Product Marking Information <br /> RELATED DOCUMENTS <br /> Documents Required to Install Equipment <br /> This intrinsically safe apparatus is only for use as part of a Veeder-Root Automatic Tank Gauging System (ATG <br /> Console with probes and sensors).To install intrinsically safe apparatus, use the specific control drawing that <br /> appears on the nameplate of the applicable associated apparatus (ATG Console): <br /> Associated Apparatus UL/cUL Control Drawing Number <br /> TLS-350,TLS-350R 331940-011 <br /> The control drawings contain information related to the correct installation of the overall intrinsically Safe System. <br /> This includes information such as maximum number of apparatus, specific apparatus allowed in the system, <br /> maximum cable lengths, references to codes, proper grounding and so on.
