Flex line commissioning Connection sequence: –Route lines –Connect rotatable connector to manifold box (both vacuum and CO2) –Leave IBL lines disconnected from detector but in vicinity. –Test vacuum system with lines attached. –Pressure test flex lines –Connect CO2 from junction box –Perform flow tests with warm CO2 (~15’C) using inter connects – Empty lines and connect to IBL –Fill with CO2 and ready for IBL cooling test 7
