2. Press the + Up or

Down buttons to set your water hardness number.
NOTE: Be sure to enter the grains per gallon (gpg) hardness of your water supply on page 5, for
future reference. If your water supply contains iron, compensate for it by adding to the
water hardness number. For example, assume your water is 20 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 30 for your hardness number.
20 gpg hardness
2 ppm iron x 5 = 10 +10
(times) 30 HARDNESS NUMBER
