If your hardness level is expressed in ppm or mg/l, first divide by 17.1 to convert to hardness
expressed in grains per gallon (GPG).
Then, calculate your Iron Adjustment Factor as follows:
(iron level in ppm or mg/l + manganese level in ppm or mg/l) x 4
Your recommended feed water hardness setting is equal to:
Hardness in GPG + Iron Adjustment Factor
To adjust the hardness setting, touch “hardness” and two blue arrows will appear. Touch the
arrows on the left or right to adjust the setting.
When you are satisfied that all of the settings are correct, press the CHECKMARK ICON in the
bottom right corner of the screen. To cancel your changes and return to the home screen,
press the “X” ICON at any time.

decrease the brightness to suit your preferences. Each time you press one of the blue
arrows, the screen brightness will change accordingly.
When you are satisfied with the brightness level, press the CHECKMARK ICON in the bottom
