2. SET WATER HARDNESS NUMBER:
Press the SELECT keypad once to display 25 (flash-
ing) and HARDNESS.
Set the grains per gallon
hardness of your water sup-
ply (determined by water
analysis or call your local
water department).
NOTE:
If your water supply contains iron, compen-
sate for it by adding to the water hardness number.
For example, assume your water is 15 gpg hard and
contains 2 ppm iron. Add 5 to the hardness number
for each 1 ppm of iron. In this example, you would
use 25 for your hardness number.
15 gpg hardness
2 ppm iron x 5 = 10
