These water softener systems have been tested by WQA and conform to NSF/ANSI 44 for specic performance claims as veried and substantiated
by test data. The rated salt eciencies above were also determined in accordance with NSF/ANSI 44 and are only valid at the salt dosage referenced
above. An eciency rated water softener is a demand initiated regeneration (DIR) softener which also complies with specic performance
specications intended to minimize the amount of regenerant brine and water used in its operation. Eciency rated water softeners shall have
a rated salt eciency 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 eciency of the water softener, the salt
dosage at that eciency, the capacity at that salt dosage and that of the eciency is only valid at the stated salt dosage. Eciency is measured by
a laboratory test described in NSF/ANSI 44. The test represents the maximum possible eciency the system can achieve. Operational eciency
is the actual eciency achieved after the system has been installed. It is typically less than the eciency 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 your local dealer for parts and service. See your owner’s manual for warranty information.
