"k Intermittent flow rate does not represent the maximum service flow rate used for determin-
ing the softeners rated capacity and efficiency. Continuous operation at flow rates greater
than the service flow rate may affect capacity and efficiency performance.
These systems conform to NSF / ANSI 44 for the specific performance claims as verified and
substantiated by test data.
The efficiency rating is only valid at the minimum stated salt dosage. These softeners were
efficiency rated according to NSF /ANSI Standard 44.
