Incoming Water Conditions
(Hardness Settings/ Iron
Settings)
Hardness setting is adjustable to match incoming water hardness in
grains/gallon. Range is 2 – 200 grains per gallon
(
gpg), in increments
of 1, with a default of 10.
Iron level is adjustable to match incoming iron level in parts per
million (ppm). Range is 0 – 3 parts per million (ppm), inincrements
of 0.5, with a default of 0.
A combined hardness setting is calculated as follows:
•Combined hardness setting = hardness setting (gpg) +
(iron level (ppm) x 6 gpg/ppm)
•Combined hardness setting is never displayed, but used in
capacity calculations.
•Iron Level of greater than or equal to 0.5 ppm will change
the START CAPACITY to change to 50% and only allow
for adjustment from 50% to 80%.
Example: Hardness set at 10 Grains, Iron Set at 1.5 ppm = Capacity
calculations use 19 Grains / 50% Start Capacity before Regen can be
triggered.
Metric Conversion Factors
(Units) Settings
•Gal / Grain / AM:PM (Imperial Settings)
•L / PPM / 24:00 (Metric)
• L / TH / 24:00 (Metric - French Degrees)
1 gallon = 3.785 liters (l)
1 grain/gallon = 17.1 ppm = 1.71 th
1 lb. = .454 kilograms (kg)
Metric - Clock is displayed in 24-hour mode without AM or PM
Metric - Date is displayed as DD/MM/YY instead of MM/DD/YY.
In general, all calculations are based on Imperial units, then
converted for display purposes to metric when metric units are
selected.
Hardness settings in Metric, increase is every 17.1 ppm per 1 grain
(Imperial) and in Metric French Degree, 1.71 th per 1 grain
(Imperial)
