C) ADVANCED LEAK DETECTION <br /> PROCEDURE <br /> A Bravo Systems Exclusive detection method <br /> CA - Clear debris from the top open area of the DoubleWall Product and ensure that the <br /> interior walls are clean of debris and visible. <br /> C.2 - Apply Vacuum to the sealed interstitial space with the Venturi Vacuum Assembly, and <br /> generate 20"-30" of vacuum for a MINIMUM of Five [ 5 ] Minutes. <br /> CHECK WITH YOUR EQUIPMENT MANUFACTURERS <br /> AWAAMANUALS FOR <br /> RNI NG GUILINES A D//OR EQUIPMENT LIIMI STION REGARDING <br /> VACUUM AND PRESSURE LEVELS. <br /> C.3 - As stated in your Instructions, the liquid level is deliberately not filled to the very top <br /> of the interstitial space. This pocket of air is necessary to visually check the topmost level of <br /> liquid all the way around the Sump for indication of a leak. <br /> C.4 - Visually inspect the interior walls for signs of trailing (very small) bubbles floating to <br /> the top of the liquid level within the interstitial space. <br /> These air bubbles are visible within the vertical and horizontal <br /> channels of the walls. For Tank Sumps look below the reducer. <br /> r On the top hat reducer of a Tank Sump, any bubbles will burp <br /> consistently. <br /> PAY CLOSE AND SPECIAL ATTENTION TO FIELD-INSTALLED <br /> f PENETRATION FITTINGS and FRP JOINTS ON TANK SUMPS. <br /> THESE ARE COMMON LEAK POINTS. <br /> AUTION <br /> Even though Bravo DoubleWall product corners and edges are thicker than the rest of the <br /> Containment sump, These areas are most susceptible to physical damage by Installing Contractors. <br /> You would do well to be extremely careful with these DoubleWall products while storing, moving, <br /> transporting and Installing these critical environmental components. <br /> 9 ii-B8000-9000-DW-11B <br />
