Regeneration Flow Diagrams
Service
The deionizer produces quality water during the Service Cycle. Water flows into the cation tank through the Cation Inlet
Valve (C2). The water then passes through the cation resin and the cation exchange takes place. The decationized water
flows into the distributors and out the bottom of the tank. The decationized water enters the anion tank through the Anion
Inlet Valve (A3). The anions are removed as the water flows down through the anion resin. The deionized water is col-
lected at the bottom of the anion tank and flows out to process through the Failsafe Valve (A2).

Service cycle.
The optional recirculation pump is operational during the Service Cycle. If water is not being drawn from the system, the
pump will re-circulate the water from the outlet of the Anion to the Inlet of the Cation, and quality will be maintained. If
there is no movement of water during periods of no use, the quality will drop causing a pre-mature regeneration to be
initiated. Check valves are supplied with the recirculation pumps.
