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.
