3.1.2. Performance flow rate characteristics
NOTE
Flow rates are indicative data. Maximum flow rate to produce in order to respect the required service
velocity for an optimal ion exchange upon resin manufacturers recommendation, regardless of the
inlet pressure.

Capacity & salt consumption setting
Cycles duration [min]
Calculation for 3 bar inlet dynamic pressure (brine draw 1.1 L/min, slow rinse 1.48 L/min, DLFC 8 L/min, BLFC 3.785 L/min) and with 1BV
for backwash, 2BV for slow rinse and fast rinse.
* Considering a 100% regeneration, variable brining OFF or manual regeneration.
** Maximum duration might be shortened by the Viridion function.
*** Maximum duration might be shortened by the variable brining option. Automatically calculated by the controller (display on the
controller shows only nearest entire minute).
