SECTION 3: REGENERATION INSTRUCTIONS
INSTRUCTIONS FOR USING REGENERATION FREQUENCY SCHEDULES:
(Time Clock Initiated Models Only)
1)
Determine adjusted hardness by adding three (3) times the iron content in parts per million (ppm) and by adding 4.5 times the manganese content in
parts per million (ppm) to the hardness in grains per gallon (gpg). The resulting number is adjusted hardness. The maximum amount of clear water
iron is 3.0 parts per million (ppm) and manganese is 2.0 parts per million (ppm).
EXAMPLE: Hardness is 14 gpg and iron is 2 ppm. Adjusted hardness is 20 gpg (14 plus 3 times 2).
2) Select regeneration frequency schedule corresponding to your model. Locate box intersected by number of persons in family and adjusted hardness
(if adjusted hardness is between two numbers in schedule, use higher number). Number in box represents frequency or number of times per 12 days
timer should be set to regenerate. Refer to How To Set Time Clock Regeneration Control to set correct frequency.
EXAMPLE: You have Model NWS100, 4 in family and 20 gpg adjusted hardness. Refer to Regeneration Frequency Schedule for NWS Series 100 and locate
box intersected by 4 in family and 20 gpg adjusted hardness. The fi gure "3" in box indicates a regeneration frequency of three times per 12 days (if a "1",
"2", "4", etc. were in box, frequencies of once, twice and four times per twelve days, respectively, would be indicated.)
