Specifications
 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).
