Notes
* Flow rates are from 10 and up to a peak of 50 litres / min. At flow rates under 10 litres /
min, the hardness may not be effectively removed from the water. If peak flow rates are
sustained for longer than 10 minutes, the softener capacity may be reduced resulting in
hard water breakthrough.
**The proportional brining control system calculates the exact amount of water and salt
required to regenerate the water softener. The amounts used will vary depending on water
usage patterns.
