29 CATALOGUE 2023 PENTAIR RESIDENTIAL SYSTEMS POUSYSTEMS More concretely: maintenance of awater softener Like a boiler, a softener should be serviced by a professional regularly, at least once a year. The technician will control data entered in the softener electronics, clean up the brine tank, the resin, injector, DLFC and BLFC, go through hydraulic cycles. This annual check ensures proper functioning of the device and maintains the quality of the drinking water supplied by the softener. The replacement of the pre-filtration cartridges and / or the possible supply of salt must be carried out according to the type of softener and the frequencies recommended by the manufacturer of the device. BLFC (Brine Line FlowController) Also called refill controller, this device controls and restricts the flow rate during the brine refill cycle. Chlorination disinfection Chlorinated compound produced by electrolysis of brine, which is then injected into the resin bed at the same time the brine is drawn into the softener. Thiswill destroy or inhibit the growth ofmicro-organisms in the softener. SBV (Safety Brine Valve) A safety float valve installed in the brine tank, shutting off the brine and the refill line to prevent over filling the brine tank. DLFC (Drain Line FlowControl) Controls and restricts the flow rate at the softener drain during regeneration phases, mostly during backwash cycle and fast rinse. DLFC is critical to control the resin bed expansion during backwash. Variable brining Also called proportional brining. At the time a regeneration should occur, the actual saturation level of the resin is sensed to adapt the regeneration proportionally to the real exhaustion rate of the resin. The goal is to optimize the production of brine to the exact need, avoiding unnecessary long regeneration cycles. Great for water and salt savings.
