About this file
This document is a Modified Chilled Water Schematic diagram for a chilled water pump relocation project at the Pearl Harbor National Park, Theater Building. The technical drawing details a complex piping system with multiple components including an expansion tank, air separator, chemical feeder, pressure regulators, valves, and control switches. The schematic outlines the sequence of operations for the chiller water pump, indicating work to be performed in existing chiller and pump enclosures, with specific points of connection and removal in the theater basement and underground conduits. The diagram includes a legend explaining various valve and control symbols, and provides technical specifications for connecting new and existing chilled water supply and return lines, with provisions for temporary bypass and system reconfiguration.
