Efficiency ratings are only valid at the lowest salt dosage and service flow rate. These units were efficiency rated according to
NSF/ANSI Standard 44.
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 WQA test data. State of Wisconsin requires additional treatment if
water supply contains greater than 5 ppm clear water iron.
Canada working pressure limits: 1.4 - 7.0 kg/cm².
These units conform to NSF/ANSI 44 for the specific capacity claims as verified and substantiated by test data.
ERR 3500R20 and ERR 3502R30 also conform to NSF/ANSI 42 for chlorine reduction as verified and substantiated
by test data from Water Quality Association (WQA).
