The Avantapure AP-5125 softener conforms to NSF/ANSI-44 standard
for the specic performance claims as veried and substantiated by test
data. The softener is a DIR efciency rated system, which also complies
with specic performance specications intended to minimize the
amount of regenerant brine and water used in its operation. Efciency
of the softener is valid only at the stated salt dosage. Efciency rated
softeners shall have a rated salt efciency of not less than 3,350 (4,000
for CA) grains of total hardness exchange per pound of salt (based on
NaCl equivalency), and shall not deliver more salt than its listed rating.
The type of salt recommended is sodium chloride, specically formulated
for water conditioning units. Efciency is measured by a laboratory test
described as NSF/ANSI-44 standard. The test represents the maximum
possible efciency that 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 softener’s capacity. System testing utilized sodium chloride
regenerant specically formulated for water conditioning units. The
softener is not intended for treating water that is microbiologically unsafe
or of unknown quality without adequate disinfecting before or after the
system. Please see service manual for user responsibility, parts and
service availability, any further restrictions, or limitations to the use of this
product.
