At higher salt dosages, the softener will treat more water between regenerations, create less overall waste, and
produce lower-hardness effluent. At lower salt dosages, the softener will use less overall salt. For dosages
below 9 #/ft 3 , consult Technical Support at the number on this manual’s front cover.
2 3
For other salt dosages, use the formula: Kgr capacity = (#(30 - #) + 16) / 8 x ft resin, where # = salt dosage in
lbs/ft 3
3
The Brine In and Slow Rinse times are set on each valve timer as a single cycle time, which is the two cycle times
added together.
4
For other salt dosages, adjust the Brine In and Brine Tank Fill times using this formula: Cycle time = Time shown x
Salt Dosage ÷ 15.
5
For an inlet pressure other than 35 psig, adjust the Brine In and Slow Rinse times using the graphs in Section 8.4
and this formula: Cycle time = Time shown x Flow at 35 psig ÷ Flow at actual psig.
6
For tank sizes that are listed with more than one possible resin amount, refer to the last letter of the model # (see
above) to determine whether to use the minimum (Y), median (X), or maximum (Z) resin volume.
7
At higher salt dosages, use 70% of salt instead; if more salt is loaded, the tank may overflow during the Brine Refill
step.
