Flow rate min / Service / Peak (l/m)*

N/A
Flow rate min / Service / Peak (l/m) (High Flow)*  10/30/50
Salt used per regeneration min / max (kg) ** 1.2/2.4
Water used per regeneration (litres)** <80

Max / min pressure (Mpa / (bar))

0.5/0.17 (5.0/1.7)

Dimension H x D x W (mm) 602 x 480 x 270

*Flow rates from 10 litres and up to the peak flow rate stated. At flow rates under 10 litres per minute, the hardness may not be effectively removed from the water.

If peak flow rates are sustained for longer than ten 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 the remaining capacity of the resin bed.
