Peerless Water 5600_5600 Econominder - Owner’s Manual - Manual (Page 4)

Service:
Hard water enters unit at valve inlet and flows down through the mineral in the mineral tank.
Conditioned water enters center tube through the bottom distributor, then flows up through the
center tube, around the piston, and out the outlet of the valve.
Preliminary Rinse:
Slow rinse of the resin bed. Water flows down through the resin bed up the bottom distributor and
out the drain.
Backwash:
Hard water enters unit at valve inlet, flows through piston, down center tube, through bottom
distributor, and up through the mineral, around the piston and out the drain line.
Water is passed through the resin bed in the opposite direction of normal flow, which flushes
suspended matter out of the resin tank. Backwashing also loosens the resin bed which becomes
compacted during the softening (in service) cycle.
Brine/Slow Rinse (Softener Only):
Hard water enters unit at valve inlet, flows up into injector housing and down through nozzle and
throat to draw brine from the brine tank, brine flows down through mineral and enters the center
tube through bottom distributor and out through the drain line.
The resin beads are washed with the strong
solution of salt water which is called the brine
solution. Since the resin beads prefer calcium
and magnesium ions, the slow rinse allows
an overwhelming concentration of sodium
ions to overpower and force the calcium and
magnesium ions off of the resin beads and are
then discharged down the drain.
Rapid Rinse:
The resin bed is rinsed to remove excess brine
solution from the tank and the resin beads are
then ready to produce soft water again.
Hard water enters unit at valve inlet, flows
through piston, down center tube, through
bottom distributor, and up through the mineral,
around the piston and out the drain line.
Settling Rinse:
Slow rinse of the resin bed. Water flows down
through the resin bed up the bottom distributor
and out the drain.
Brine Tank Refill (Softener Only):
Hard water enters unit at valve inlet, flows up through the injector housing, through the brine valve
to refill the brine tank. Valve is now delivering soft water to the home. Raw water is refilling the brine
tank to make a brine solution for the next regeneration.
Regeneration:
When the valve is in Regeneration, raw water is being passed to service until rapid rinse is
complete.
