The efficiency rating is valid only at the minimum salt dose and rated service flow. 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 sustained 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 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 contaminants that reduce a softener's capacity. | | Model W􀀝􀀚S􀀎􀀊 | Model W􀀝􀀚S􀀎􀀎 | | --- | --- | --- | | Model Code | LL40 | LL44 | | Rated Softening Capacity (Grains @ Salt Dose) | 11,900 @ 2.4 lbs.

FAQs

How do I contact support for the water softener installation or maintenance questions?

Call the toll-free number 1-866-986-3223, Monday–Friday 8 AM–7 PM EST, or visit www.whirlpoolwatersofteners.com. When calling, provide the model and serial number found on the rating decal.

What is demand initiated regeneration (D.I.R.) and why is it important?

The units use a demand initiated regeneration feature that complies with performance specifications to minimize regenerant brine and water usage during operation. Efficiency ratings apply at the minimum salt dose and rated service flow.

What factors can reduce operational efficiency compared with the rated efficiency?

Operational efficiency is typically less than rated efficiency due to application factors such as water hardness, water usage, and other contaminants that reduce the softener’s capacity.
