BRAVO Flushing Procedure <br /> PROBLEM SOLVED <br /> Doublewall Flushing and Replacing Fluid <br /> This Instruction Set for the procedure of Flushing and Replacing Interstitial Fluid must be <br /> performed by a Bravo Certified Contractor for DoubleWall products. <br /> DRAINING THE INTERSTITIAL FLUID <br /> 1) Prepare a clean empty bucket per sump. <br /> 2) Disconnect line from the upper test port (highest connection point). In a UDC this is the atmospheric <br /> manometer, and in a Tank Sump that is the breather tube. Reconnect the gauge assembly and connect <br /> to the ball valve in the closed position and tubing from the Bravo T900 Kit. <br /> 3) Place the empty collection bucket near the low point and bottom test port. In UDC's, disconnect tube <br /> from the large manometer and place the tube into the empty collection bucket. For Tank Sumps, the <br /> base of the Tank Sump will have a test port with the plug in it. One can connect a Y2" nipple with a <br /> closed ball valve to the test port to have the ability to limit flow. Have the flow into the empty bucket. <br /> 4) In the case of a UDC the flow will start when the ball valve on the upper test port is opened. The fluid <br /> will start to flow freely and you have the ability to control the flow. <br /> 5) During the process stop the flow of fluid so that a new collection bucket can be put in place. <br /> 6) Once the level is at its lowest point one can manually assist by connecting air hose to <br /> gauge assy and apply less than 4 psi to remove additional liquid removal. <br /> FLUSHING THE SUMP WITH WATER <br /> 1) With the Sump drained of incorrect or contaminated fluid prepare two buckets of water to flush out any <br /> remaining fluid. The collection bucket will still need to be empty and in position. <br /> 2) Prime the line with the ball valve in the closed position with clean water. Insert the primed line into water <br /> supply, with the collection bucket in place open the ball valve. <br /> 3) Flush with water until fluid that is coming out the bottom test port is clear and clean. <br /> UL2447 is the standard for secondary containment and covers sumps <br /> and lids, sump fittings and sump accessories. Products are tested in <br /> accelerated conditions that have long term use in environments with <br /> S��NF�ST extreme heat and cold, aggressive biofuel and ethanol blends, and <br /> extreme soil environments. <br /> Get Bravo Certified Today — Contact Your Sales Manager <br />
