Automatic Hard Water Bypass During Regeneration
The regeneration cycle can last 30 to 180 minutes, after which soft water service will be re-
stored. During regeneration, hard water is automatically bypassed for use in the household.
Hot water should be used as little as possible during this time to prevent hard water from
filling the water heater. This is why automatic regeneration is set for sometime during the
night and manual regenerations should be performed when little or no water will be used in
the household.
Normal regeneration time is 2:00 AM.
New Sounds
You may notice new sounds as your water softener operates. The regeneration cycle lasts
up to 180 minutes. During this time, you may hear water running intermittently to the drain.
When the system capacity is near exhausted, a regeneration is necessary to restore the sys-
tem to full capacity. The table below explains the regeneration steps.
Regeneration Process and Precision Brining
System Configuration
Step Name
Description
#1
Brine Making
A precise calculated amount of fresh water is added to the brine tank to make
enough brine to regenerate only the exhausted portion of the ion exchange
resin. Note: 70% of the required fresh water is added in Step #5 in the previ-
ous regeneration. The default brine making time is 30 minutes.
#2
Brine
The brine solution is introduced slowly to the bottom of the tank flowing up
through the ion exchange resin pushing the hardness out to drain and restor-
ing system capacity.
#3
Back Wash
Fresh water is introduced to the bottom of the tank flowing upwards expand-
ing the ion exchange resin to rinse out any dirt or small particles to the drain
and to un-compact the bed to restore full service flow rates.
#4
Rinse
Fresh water is introduced from the top of the tank down flowing down through
the ion exchange resin rinsing any excess brine solution out to the drain.
#5
Refill
A fixed amount of soft water is added to the salt tank to prepare 70% of the
fully saturated brine for the next regeneration. Note: Step #1 will "top off" the
amount of water needed based on the percentage of exhausted resin to be
regenerated.
