SECTION I. INTRODUCTION
Congratulations, you have just purchased one of
the finest Point-of-Use Nitrate Reduction
Appliances available.
Like any other fine product, this appliance requires
periodic maintenance in accordance with the
schedule outlined. Have your water checked
periodically to verify nitrate reduction.
Your new Nitrate Reduction (NRS-1) Drinking
Water system uses a non-leaching material to
reduce unwanted nitrates in a water supply.

NOTE: The NRS-1 may be installed on waters containing nitrate; however the total nitrate concentration of the incoming water
supply should be less than 21.0 ppm. Water containing nitrate concentration greater than 20.0 ppm will greatly reduce the
cartridge capacity and leave potential for harmful levels of nitrate bleed through. Have your water checked periodically to
avoid harmful levels of nitrate bleed through.
