Class A covers the 500PN up to 16.5 GPM and the 750PN up to 27.4 GPM; the 1000P runs up to 100 GPM.

Lower UVT or a higher required dose means less flow per unit. The unit alarms if dose falls short.

In exchange they give up flow (16.5 and 27.4 GPM against 40) and need 75% UVT or better. Their standard flow restrictor also adds pressure drop: 22.7 psig at 75% of maximum flow, per the manual.

The O\u0026amp;M manual recommends the prefilter and requires turbidity at 1 NTU or less and TDS up to 1,000 mg\/L.
