DYNAMIC INLET PRESSURES
Hot & Cold Inlet Pressures
For optimum operation it is recommended that the
hot and cold water supply pressures be balanced
/- 10% for both static and dynamic pressures.
Minimum
20kPa
Maximum
500kPa
STATIC INLET PRESSURES
Hot & Cold Inlet Pressures
For testing purposes/ system commissioning
Maximum
1600kPa
^ Where cold inlet temperature may exceed recommended range due to seasonal
variation, a 5°C temperature differential between the inlet cold supply and outlet mixed
temperature setting must be maintained.
NOTE: Notwithstanding the above, compliance with the Plumbing Code of Australia
(PCA) and AS/NZS 3500 must be maintained.
