2. Press the UPA or DOWN _r" buttons to set
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.

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 Ippm) or
milligrams per liter (mg/I), simply divide by 17.1
to get the equivalent number of grains per
gallon.
