PERFORMANCE DATA SHEET
This softener conforms to NSF/ANSI 44 for the specific performance claims as verified and substantiated by test data.
This model is efficiency rated. The efficiency rating is valid only at the minimum stated salt dose. It has 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 its operation. The softener has a rated salt efficiency of not less than
3350 grains of total hardness exchange per pound of salt (based on sodium chloride) and shall not deliver more salt
than their listed rating. 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 efficiency due to individual application
factors including water hardness, water usage, and other contaminants that reduce the softener’s capacity. Use clean
water softening salts only, at least 99.5% pure. For best results use nugget, pellet or coarse solar salts. This system is
not intended for treating water that is microbiologically unsafe or of unknown quality without adequate disinfection
before or after the system. Refer to Use and Care Manual for further details on installation and maintenance, user’s
responsibilities, parts and service, and further restrictions, or limitations to the use of the product. GE complies with
applicable local warranty laws via its authorized distributors and re-sellers.
