Intermittent flow rate does not represent the maximum service flow rate used for determining the conditioner’s rated capacity and efficiency.
- Continuous operation at flow rates greater than the certified flow rate may affect capacity and efficiency performance. The validity of these flow rates is verified by NSF.
- Increased amounts of clear water iron can reduce conditioner’s efficiency. Refer to owner’s manual for details. Wisconsin requires additional treatment if water supply contains greater than 5 ppm clear water iron.
- When operated at 35 psi water pressure.
- Maximum pressure for Canadian use is 7.0 Kg/cm2
