Installer Manual Fleck 4600 SXT - System sizing
To calculate the refill duration:
The refill flow rate is controlled by the refill controller (BLFC). The relation between the BLFC size,
the tank size and the resin volume is given in the valve specifications.
To calculate the refill duration:
T = V / Q

V = D x BV / S

When calculating the time required to draw the brine, take into account that the volume of
