10.2 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.
10.3 Spare Parts
Only original spare parts made by Vertiv must be used. Using third-party material will invalidate the warranty. When
seeking technical assistance, always refer to the component list supplied with the equipment, and specify the model
number, serial number and, if available, the part number.
NOTE: When replacing a faulty component, follow the relevant manufacturer instructions.
NOTE: When the spare parts must be brazed, be careful not to damage the internal parts (gaskets, seals,
O-rings, etc.).
