1. Press the UP or
hardness of your water supply, in grains per gallon.
The default is 25.
NOTE: If your water supply contains iron, compen-
sate 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.
2 ppm iron x 5 = 10
(times)

ber, press the SELECT button, and the display will
