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.
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.

Description
#1
Back Wash
Fresh water is introduced to the bottom of the tank flowing upwards expanding
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.
#2
Brine
The brine solution is introduced slowly from the top of the tank flowing down
through the ion exchange resin pushing the hardness out to drain and restoring
system capacity.
#4
Rinse
Fresh water is introduced from the top of the tank flowing down through the
ion exchange resin rinsing any excess brine solution out to the drain.
#5
Refill
Fresh water is added to the salt tank to prepare and insure fully saturated brine
for the next regeneration.
