Issue_Da = 4 to -Au ust�X�0 Veeder-Root Secondary Containment Leak Detection (SOLD) TLS-350/ProMax/EMC Console with Vacuum Sensors 857280-100, 200, 30x PRESSURE/VACUUM INTERST TIAL MONITOR Certification: Certified as equivalent to European leak detection standard EN -13160, Class I leak detection system. Operating Principle: System uses vacuum generated by the turbine pump to continuously maintain a partial vacuum within the interstitial space of double -walled tanks and double -walled piping. System is designed to activate a visual and acoustic alarm, and optional turbine pump shutdown before stored product can escape to the environment, and is capable of detecting breaches in both the inner and outer walls of double -walled tanks and double -walled piping. Alarm Condition: System alarms when a liquid or air leak occurs which causes the interstitial vacuum to decrease (pressure to increase) and the system js unable to maintain minimum vacuum. System will also alarm if liquid is detected in the interstitial space, or if the vacuum level in the interstitial space decreases at a rate exceeding 85±15 liters/hour. Applicability: Underground double -walled tank, connected double -walled piping, and Aer connected interstitial spaces storing gasoline, gasohol, diesel, heating oil #2, kerosene, aviation fuel, mottar. of ater. Manufacturer's Specifications: t/ Alarm will activate when interstitial vacuum decreases to�vacuu (3. "Hg}. Default maximum vacuum level (pump -off pressure) is sl Gcu�i n (16. g), but can be set as low as 4 psi (8.2" Hg) if the monitored system requires that a'! Werlevel Qf vacuum be maintained. The interstitial space shall be rated for the operattig vaGuu �t of tike leak detector, regardless of temperature and groundwater level fluctuations. t `� Volume of monitored interstitial. space must7texile\ 8 3 or tanks and 10 m3 for piping. When monitoring double -walled tanks a I Id sensor ust be located at lowest point of interstitial space. Calibration: Functional and operational afe s sou be performed in accordance with manufacturer's instructions. Comments: Interstitial space is tested con n�uou,S System is connected to the inters#itial space by a single vacuum line. Vacuum is generated by the turbine pump, and is measured and controlled by a vacuum sensor.
