provide high flow rates over a wide range of applications — provides long-lasting
operation
• Chemical free oxidation of Ferric, Ferrous or Bacterial Iron by air induction;
provides cost-efficient operation and eliminates the use of harsh chemicals
• Proprietary media blend provides excellent depth filtration of oxidized iron while
increasing pH to enhance iron reduction
• Patented one-piece mineral tank has no glue joints or heat welded seams to crack
or rust, providing longer life and compatibility with many media types and water
conditions
• Semi-transparent mineral tank for ease of media level inspections without
disassembly
• Unique bypass valve with state of the art design features — Full flow bypass valve
incorporates four positions, including a diagnostic position that allows service

NOTES:
1. Replenishment of pH adjusting component of media may be required periodically, the frequency of which is dependant on raw water pH, manganese concentration and water
consumption rate. Consult dealer for more information.
2. For satisfactory performance, indicated flow rates should not be exceeded. Flow rates are adequate for normal residential applications. Do not use Service rates when sizing com-
mercial applications or if treated water is to supply a geothermal heat pump, swimming pool, etc.). Contact dealer before selecting equipment.
3. For system to operate properly, pumping rate of well pump MUST be sufficient to backwash unit at rate specified.
4. Pipe Size is 1” (2.5 cm).
