Regeneration Sequence Steps and Purpose
Brine Tank Fill - Brine tank is refilled with a calculated amount of water, determined by the water use from the previous
regeneration, to dissolve exactly the salt amount required for current regeneration.
Brine Making – The system is pausing to allow for full saturation of the brine solution. During the brine making cycle
service water continues to be delivered softened.
Brine In - Brine is ejected from the brine tank and passes through the resin bed in an upward flow, thus removing calcium
and magnesium that has accumulated on the resin and is flushed to drain. As the beads swell during the full brine cycle
the debris (i.e. iron) which may be attached to the beads will be released and be removed more readily during the following
backwash cycle.
Slow Rinse - After the brine has been introduced, brine air check is closed, allowing water to flow through the ejector at a
slow rate, displacing the brine remaining in the resin bed. This insures good utilization of the brine.
Backwash - Flow through the resin bed is reverse of the service flow. Water flows upward at a controlled rate expanding
and agitating the resin and fluidizing the bed. This action loosens sediment and iron that may have collected on the resin
during service and is flushed to drain. Resin fines which developed during service due to oxidation are also removed.
Note: Applications with chlorine levels above 0.5 ppm should have protective removal systems before the
water softener unit
Fast Rinse - The resin is now flushed downward at a set flow rate. This reclassifies the bed and rinses out any remaining
brine left in the resin bed.
After fast rinse step the unit is ready for service, thus completing the regeneration cycle.
While the unit is in regeneration (but not recommended) service is available through the valve with untreated water.

Water Hardness
Set In your local Grains per Gallon (example 25 grains)
[ 25 ]
If a number reads “ppm” or “mg/l” divide that number by 17.1 to calculate grains per gallon
System Capacity
Example: 24,000 Grain Capacity - Set by Factory
[ 24 ]
Example calculated by 4 lbs salt per cubic foot of resin, California SB1006 Compliance for the 10 x 54
Do Not reset without resetting salt setting and salt dosage for proper system operation
Regeneration Time [ 2:00 ]
Example: standard 2:00 am pm indicator OFF
