PROULUURL HR Alk PRESSURE TESTING J#PERTANKTM ANNULAR SP., E In the event local regulating jurisdictions insist on a positive pressure test for the SUPERTANKTm annula space against Trusco's recommendation, the following procedure must be adhered to or the warrant is invalid. Trusco must be notified of the time and place of the test at least 24 hours in advance of the test and a copy of this form must be completed, signed by all parties, and returned to Truscc immediately upon completion of the test. PRECONDITIONS 1.Trusco representative must be notified when a SUPERTANKTm annulus is required to be pressure tested. 2.Install the 2" fiberglass monitor pipe and bell x female adapter coupling per Section 10E of the installation instructions 3.SUPER TANK TM must be backfilled over the top of the tank as shown in Figure PT-1A (attached). 4.The valved inlet manifold and valved transfer manifold must each have dual 0-5 psig pressure gages. See Figure PT-2/ 5.Maximum air pressure applied to steel primary tank shall be 5.0 psig. 6.Maximum air pressure applied to annular space shall be 5.0 psig. PROCEDURE 1.Apply sealant and install plugs, valved outlet manifold, valved inlet manifold with dual 0-5 psig gages and valved transfE manifold with dual 0-5 psig gages as shown in Figure PT-1A. Make sure all manifold valves are closed. 2.Start compressor. 3.While monitoring the two inlet manifold pressure gages, open the inlet manifold valve and pressurize the primary tan until the inlet manifold pressure gages read the maximum of 5.0 psig. Close the inlet manifold valve. NOTE : If, while applying air into the primary tank, both gages do not read within 0.5 psig of each other, stop th test by closing the inlet manifold valve, depressurize the primary tank by opening the outlet manifold valve, replace bot rages and start over at step 2 4.Next, with the inlet manifold valve still closed and while monitoring the two transfer manifold gages, open the transfE manifold valve to pressurize the annular space to a maximum of 5.0 psig. Close the transfer manifold valve. NOTE : If, while applying air into the annular space, both gages do not read within 0.5 psig of each other, stop th test by closing the transfer manifold valve, depressurize the annular space by carefully removing one gage, replace bot gages, and start over at step 2- 5. 5.Hold pressure for the desired length of time. 6.Depressurize the system by first opening the transfer manifold valve. Next open the outlet manifold valve to purge bot the primary tank and the annular space at the same rate. CERTIFICATION The undersigned do hereby certify that the annulus pressure test was performed in strict conformance with this procedure for the SUPERTANKT"' listed below.
