manual abstract
THE NF-SERIES GIVES YOU MORE 1. One control valve operates both tanks and provides better flow rates. 2. Takes less time and space to install. 3. Provides softened water 24 hours per day on demand with 1-1/2” flow meter. 4. Uses soft water to regenerate. 5. There are no time clocks to set or day pins to worry about. 6. Electricity is only used during regeneration. 7. Manufactured and tested accordingly to Water Quality AppLICATIONS Apartment Buildings Households Boiler Treatment Laundries Car Washes Motels and Hotels Clubs Nursing and Rest Homes Commercial Buildings Office Buildings Condominiums Restaurants Factories R.O. Pre-Treatment Hospitals Schools Association Voluntary Industry Standards. 1) The control valve and second tank adapter are solid brassassuring you durability and long life. 2) Two self cleaning teflon coated pistons control the regeneration and alternating from unit to unit with conditioned water. They are hydraulically balanced to equalize pressure on bothsides of the piston, allowing it to shift smoothly and quietlyregardless of water pressure. Large plastic spacers andrubber seals protect the pistons from sediment in water andimprove service flow rates. 3) The 1.5” meter allows for capacities from 625 to 53,125gallons between regenerations and will measure flow ratesaccurately between 1.5 and 75 gpm. The 1.5” low flow meter allows for capacities from 310 to 26,350 gallons between regenerations and will measure flow rates accurately between0.7 and 40 gpm. 4) The NF-SERIES timer doesn’t require a time of day settingsince it adjusts automatically to meet your needs. Regeneration 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 including backwash, brine and slow rinse, rapid rinse and brinetank refill. 6) In addition to regenerating with soft water, the NF-SERIES uses electricity only during regeneration, therefore poweroutages 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 andcosts 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 minimalpressure loss. C) Hi-Capacity Cation resin has uniform and stable resin beadsassuring long life and maximum soft water. D) Gravel underbedding assures full usage of mineral beds andallows 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 andminimizing bulging. G) Polypropylene salt grid allows insoluble materials to settle out. A B C D G F E NF-SERIES Specifications MODEL NAME RESIN CU. FT.
