Quality Rinse
The Quality Rinse Cycle precedes regeneration, or it may be triggered by a false spike in the TDS measurement. The
Cation Resin has been regenerated with Hydrochloric Acid and the Anion Resin has been regenerated with Sodium
Hydroxide. The water coming out of the Cation Column must be between 2.5 and 3.0 pH with 0 Hardness, and the water
coming out of the Anion Column should be somewhere between 6.8 and 8.1 pH. The Quality Rinse Cycle is used to rinse
the Deionizer up to the desired pre-set quality. The Raw Water enters the Cation Column, flows down through the resin
and out the bottom of the column as decationized water and into the Anion Column. The decationized water flows down
through Anion Resin and out the bottom of the column through the Sensor Cell and out to drain through the Anion Fast
Rinse Valve (A6) and to service through the Service Valve (A2). The water running to drain should be low quality deion-
ized water.

Quality rinse cycle.
When the TDS of the water is below the High TDS Limit setting, the Anion Fast Rinse valve (A6) will close. The Deionizer
has returned to the Service Cycle. If the TDS remains above TDS limit, the unit will enter the regeneration cycle. If the
TDS remains above TDS limit after a regeneration cycle, the unit will enter error mode.
