Specifications & Performance Claims
p Intermittent flow rate does not represent the maximum service flow rate used for determining the unit’s rated capacity and effi-
ciency. Continuous operation at flow rates greater than the service flow rate may affect capacity and efficiency performance.
The validity of these flow rates is verified by Water Quality Association (WQA).
¢ Capacity to remove clear water iron is substantiated by independent laboratory test data. State of Wisconsin requires additional
treatment if water supply contains greater than 5 ppm clear water iron.
u Canada working pressure limits: 1.4 - 7.0 kg/cm².
Ù Model ERRC3702R50 has not been tested or certified by NSF International or the Water Quality Association.
These units conform to NSF/ANSI 44 for the specific performance claims as verified and substantiated by test data.
