The document describes the start up and shut down sequence of an absorption chiller. It involves checking parameters like generator temperature and pump connections before starting in either local or remote mode. The chiller can then operate in either cooling or heating mode depending on conditions. Cooling involves turning on chilled water pumps while heating uses hot water pumps. Sensors monitor water flow and temperatures during operation. The shutdown sequence involves turning components off in a specific order over time periods after a stop signal is received.
