your water hardness number.
NOTE: 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
or iron. In this example, you would use 30 for
your hardness number.
2 ppm iron x 5 = 10 +10
(times)
3. When the display shows your water hardness
(in grains per gallon), press MODE/SET to
accept.
You can get the grains per gallon (gpg)
hardness of your water supply from a water
analysis laboratory. If you are on a municipal
supply, call your local water department. Or
call Legend Technical Services, an independent
laboratory, to request a water hardness test
kit at 1.800.949.8220, Option 4. If your report
shows hardness in parts per million (ppm) or
milligrams per liter (mg/l), simply divide by 17.1
to get the equivalent number of grains per
gallon.
