12.3 Fluid and Piping Maintenance
Maintaining the system fluid quality is required throughout the life of the system. Fluid and piping system maintenance
schedules must be established and performed. A coolant fluid maintenance program must be established that will evaluate
fluid chemistry and apply necessary treatment. The complexity of water condition problems and the variations of required
treatment programs make it extremely important to obtain the advice of a competent and experienced water treatment
specialist and follow a regularly scheduled coolant fluid system maintenance program.
Perform periodic inspections of the heat exchanger and coolant fluid piping system for leaks and visible damage.
