This piping schematic outlines the mechanical connections for a life safety services heat exchanger, separating the life safety services scope from the general mechanical scope with a dashed boundary line. The chilled water supply and return lines interface with the heat exchanger alongside a circulation pump, a modulating control valve, and a line size bypass valve. Four motorized open and closed valves regulate flow across the risers for both chilled water and heating water systems. Temperature sensors and flow components are positioned along the supply and return headers to monitor system performance.
