All Systems above tested at 35psi +/- 5 psi, pH of 7.5 +/- 0.5, Capacity Testing Flow Rate = 50% of the rated service flow rate
for the various size systems.
Tested and Certified by WQA against NSF/ANSI
Std. 44 & 372 for “lead free” compliance.
These water softener systems have been tested by WQA and conform to NSF/ANSI 44 for specific performance claims as verified and
substantiated by
test data. The rated salt efficiencies above were also determined in accordance with NSF/ANSI 44 and are only valid at the sal
t dosage referenced above.
An efficiency rated water softener is a demand initiated regeneration (DIR) softener which also complies with specific performa
nce specifications intended
to minimize the amount of regenerant brine and water used in its operation. Efficiency rated water softeners shall have a rate
d salt efficiency of not less
that 3350 grains of total hardness exchanged per pound of salt (based on NaCl equivalency) (477 grams of total hardness exchang
ed per kilogram of salt),
and shall not deliver more salt than its listed rating. The rated efficiency of the water softener, the salt dosage at that ef
ficiency, the capacity at that salt
dosage and that of the efficiency is only valid at the stated salt dosage. Efficiency is measured by a laboratory test describ
ed in NSF/ANSI 44. The test
represents the maximum possible efficiency the system can achieve. Operational efficiency is the actual efficiency achieved af
ter the system has been
installed. It is typically less than the efficiency due to individual application factors including water hardness, water usag
e, and other contaminants that
reduce the water softener’s capacity. These systems are not intended to be used for treating water that is microbiologically u
nsafe 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.
