            ProSpec  Series 5024 and 5025
            Automatic Changeover System
            The 5024 (brass) and 5025 (stainless steel) Changeover System
            is a fully automatic system designed to provide an uninterrupted
            flow of gas from two sources. When one source is in service
            providing the gas to process; the other source is on standby,
            and comes on-line when the current source has depleted.
            The changeover to the standby source occurs automatically.
            Typically this system is used for single cylinder per side but can
            be configured for multiple cylinders per side please see page
            E •296 for header extensions.
