1) The control valve and second tank adapter are solid brass
assuring you durability and long life.
2) Two self cleaning teflon coated pistons control the regenera-
tion and alternating from unit to unit with conditioned water.
They are hydraulically balanced to equalize pressure on both
sides of the piston, allowing it to shift smoothly and quietly
regardless of water pressure. Large plastic spacers and
rubber seals protect the pistons from sediment in water and
improve service flow rates.
3) The 1.5” meter allows for capacities from 625 to 53,125
gallons between regenerations and will measure flow rates
accurately between 1.5 and 75 gpm. The 1.5” low flow meter
allows for capacities from 310 to 26,350 gallons between re-
generations and will measure flow rates accurately between
0.7 and 40 gpm.
4) The NF-SERIES timer doesn’t require a time of day setting
since it adjusts automatically to meet your needs. Regenera-
tion can take place as often as every 90 minutes if needed.
5) The NF-SERIES has an adjustable cycle programmer. This
allows you to efficiently monitor all regeneration cycles in-
cluding backwash, brine and slow rinse, rapid rinse and brine
tank refill.
6) In addition to regenerating with soft water, the NF-SERIES
uses electricity only during regeneration, therefore power
outages do not affect metering. A convenient cycle position
readout dial indicates which unit is in service and the status
of the other unit. It has no complicated interlock wiring and
costs less to install.
A) Fiberglass and polyglass mineral tanks provide rust and cor-
rosion free service for years. National Sanitation Foundation
approved.
B) 1.5” high flow hub & lateral distribution system for minimal
pressure loss.
C) Hi-Capacity Cation resin has uniform and stable resin beads
assuring long life and maximum soft water.
D) Gravel underbedding assures full usage of mineral beds and
allows for a smooth and constant water flow for service and
regeneration.
E) Safety brine valve acts as a secondary shut-off in case of a
power failure during regeneration.
F) High density polyethylene brine tank has exceptional envi-
ronmental stress crack properties, eliminating cracking and
minimizing bulging.
G) Polypropylene salt grid allows insoluble materials to settle out.
