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.

*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

This system conforms 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.

This model is efficiency rated. The efficiency rating is valid only at the minimum salt dose and rated service flow.

The softener has a demand initiated regeneration (D.I.R.) feature that complies with specific performance specifica-

tions intended to minimize the amount of regenerant brine and water used in its operation.

This softener has a rated softener efficiency of not less than 3,350 grains of total hardness exchange per pound of

alt (based on sodium chloride) and shall not deliver more salt than its listed rating or be operated at a sustained

maximum service flow rate greater than its listed rating. This softener has 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 laboratory 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 contami-

nants that reduce a softener's capacity.
