These water softener systems have been tested by WQA and conform to NSF/ANSI 44
for specic performance claims as veried and substantiated by test data. The rated salt
efciencies above were also determined in accordance with NSF/ANSI 44 and are only valid
at the salt dosage referenced above. An efciency rated water softener is a demand initiated
regeneration (DIR) softener which also complies with specic performance specications
intended to minimize the amount of regenerant brine and water used in its operation. Efciency
rated water softeners shall have a rated salt efciency of not less that 3350 grains of total
hardness exchanged per pound of salt (based on NaCl equivalency) (477 grams of total
hardness exchanged per kilogram of salt), and shall not deliver more salt than its listed rating.
The rated efciency of the water softener, the salt dosage at that efciency, the capacity at
that salt dosage and that of the efciency is only valid at the stated salt dosage. Efciency is
measured by a laboratory test described in NSF/ANSI 44. The test represents the maximum
possible efciency the system can achieve. Operational efciency is the actual efciency
achieved after the system has been installed. It is typically less than the efciency due to
individual application factors including water hardness, water usage, and other contaminants
that reduce the water softener’s capacity. These systems are not intended to be used
for treating water that is microbiologically unsafe or of unknown quality without adequate
disinfection before or after the system. Refer to the system Installation and Service Manuals
for set-up and programming instructions.Contact OMNIFILTER for parts and service. See your
owners manual for warranty information.Important Notice: For conditions of use, health claims
certied by the California Department of Public Health and replacement parts, see product data
sheet.
