11-111 CSLD TroubleshootingCSLD collects information during each idle time to form a highly accurate leak detection database. Since thedatabase is being constantly updated, leak test results are always current. Periodic leak tests are performed usingthe best data from up to the previous 28 days, and test results are continuously updated as new data is gathered.Invalid data is discarded and only the best data is used to ensure accurate leak test results and fewer false alarms.Test results are provided automatically every 24 hours at 8:00 a.m.CSLD Tank LimitationsAll applications of CSLD should conform to the following installation guidelines.MAXIMUM TANK CAPACITYSingle tank - 30,000 gallonsManifolded tanks - 30,000 gallons per manifolded set (3 tanks maximum per set).MONTHLY THROUGHPUT GUIDELINES*Total capacity of manifolded tanks establishes the throughput restrictions for that product.Installations exceeding these limitations may not pass monthly tests.CSLD Block DiagramsFigure 11-1 illustrates the CSLD decision process in block diagram form and Figure 11-2 diagrams the timing ofevents during a CSLD test.Table 11-1.
