When you call, please be prepared to provide the model and serial number,
found on the rating decal, typically located on the rim below the salt lid hinges.
These models are efficiency rated. The efficiency rating is valid only at the minimum salt dose. These softeners
have a demand initiated regeneration (D.I.R.) feature that complies with specific performance specifications intended
to minimize the amount of regenerant brine and water used in their operation.
These softeners have a rated softener efficiency of not less than 3,350 grains of total hardness exchange per pound
of salt (based on sodium chloride) and shall not deliver more salt than their listed rating or be operated at a sus-
tained maximum service flow rate greater than their listed rating. These softeners have been proven to deliver soft
water for at least ten continuous minutes at the rated service flow rate. The rated salt efficiency is measured by lab-
oratory tests described in NSF/ANSI Standard 44. These tests represent the maximum possible efficiency that the
system can achieve. Operational efficiency is the actual efficiency after the system has been installed. It is typically
less than the rated efficiency, due to individual application factors including water hardness, water usage, and other
contaminants that reduce a softener's capacity.
*Capacity to reduce clear water iron is substantiated by WQA test data. State of Wisconsin requires additional
treatment if water supply contains clear water iron exceeding 5 ppm.
**Canada working pressure limits: 1.4 - 7.0 kg/cm

***Intermittent flow rate does not represent the maximum service flow rate used for detemining the softener’s
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.
Variable Salt Dose: The salt dose is selected by the electronic controls at regeneration time based on the
amount needed.
