Intermittent flow rate does not represent the maximum service flow rate used for determining
the softener’s rated capacity and efficiency. Continuous operation at flow rates greater than the
service flow rate may affect capacity and efficiency performance.
k
Capacity to reduce clear water iron is substantiated by laboratory test data. State of Wisconsin
requires additional treatment if water supply contains clear water iron exceeding 5 ppm.

m
Typical residential chlorine concentration is 0.5 to 1.0 ppm.
n
From independent laboratory test data.
This system conforms to NSF/ANSI Standards 42 & 44 for the specific performance claims as
verified and substantiated by test data.
Variable Salt Dose:
The salt dose is selected by the electronic controls at regeneration time
based on the amount needed.
