indicates how many gallons of soft water remain before a 
regeneration will take place.
NOTE: FOR WATER WITH RUST STAINS:
If iron is present in the water supply as evidenced by red 
stains on clothes, fixtures, toilets, etc., add 12 grains per 
gallon to the actual water hardness.
To keep the softener resin bed iron free, mix two ounces of 
Super Iron Out® or similar iron cleaner with every 80 lbs. 
of salt added to the brine compartment, or use salt that 
contains an iron control agent.
D. THE REGENERATION CYCLE
The regeneration cycle will take between 84 and 104 
minutes, and will go through 8 different cycles. It will be 
normal to hear water flowing during this time. Water will be 
available for use during the regeneration process, but it will 
not be softened. Figure C shows approximate cycle time for 
each process.
E. STARTING THE UNIT
1) To ensure unit is installed and working properly,
briefly rotate the indexing knob clockwise through 
the following cycles: “Backwash”, “Brine Rinse”, and 
“Brine Refill” (about 60 seconds for each cycle.) While 
in each cycle, listen for water flow, and check system 
for any leaks.
2) Return indexing knob to “Service” position. Water flow
should stop. The softener is now ready to provide 
softened water on demand.
3) The control valve will actually meter the water flow,
and regenerate only after a specific amount of water 
has been used. Not only will you enjoy softened water, 
but you will enjoy the economical savings as well.
