Operating Parameters

  • Water source: municipal or pre-treated well water.
  • Feed water quality/TDS: <1500ppm
  • Inlet water temperature: 4-30 degrees C
  • Inlet water pressure: <3 bar*
  • Inlet pH Range: 6.50-8.50
  • Maximum Iron: <0.3ppm

*RO systems require pressure to operate. Variations in pressure either too high or low can cause changes in purified water quality. RO systems can operate with a minimum pressure of 3 bar although 4 bar is more ideal. Systems should also be limited so that they do not exceed the maximum 6 bar operating pressure. This is normally done with a pressure reducing valve. A pumped RO system is a better choice in low mains pressure areas.

Accessories included with the system

  • Feed water adapter, feed valve, drain saddle.
  • Pressure tank (total vol. 12 L/3.2 gal, usable vol. up to 7 L/1.8 gal).
  • Colour tubes for easy installation.
