These systems conform to NSF/ANSI 44 for the specific capacity claims as verified and substantiated by test data.
✦ Intermittent flow rate does not represent the maximum service flow rate used for determining the softeners rated capacity and efficien-
cy. Continuous operation at flow rates greater than the maximum service flow rate may affect capacity and efficiency performance. The
validity of these flow rates is verified by NSF.
◪ Efficiency rating is only valid at the minimum stated salt dose and service flow rate. These softeners were efficiency rated according
to NSF/ANSI standard 44.
◓ Capacity to remove clear water iron is substantiated by WQA test data.
◮ Working pressure for Canadian use is 1.4 -- 7.0 kg/cm@.
