All specifications, stated operational flow rates, and output water temperatures are valid within the range of water conductivity:
›
80μS/cm to 1300μS/cm + 15% at 68°F (μS–microSiemens)
›
1.25kΩ-cm to 7.7kΩ-cm + 15% at 68°F
NOTE: Water conductivity may be less than 80μS/cm. Reduce flow rate to achieve comfortable water temperature. Water
conductivity greater than 1300μS/cm + 15% will generate an error condition. In this circumstance, the appliance will shut down
safely without damage.
