Determine the Controller Setting Number
A. For municipal water, call the water department to determine
the hardness and pH of your water supply.
B. For well water, use the hardness test strips provided with your
appliance or have a sample of your untreated water tested by a
water testing laboratory.
1. Test Strips—Follow the instructions on the test strips.
If the color on your test strip is between two readings,
use the higher number. This number gives the hardness
in grains per gallon and parts per million (mg/L).
2. Testing Laboratory—To ensure proper settings, have a sample of your untreated water tested
for iron and pH. To find a facility to test your water sample, check your Yellow Pages under Water
Analysis or Water Testing or contact the company below to conduct a test for you.

C. Determine the controller setting as follows:
D. If your water supply has an excessive amount of iron, do not add 15 to the grains per gallon
hardness (257 mg/L). Instead enter the hardness grains per gallon (mg/L) as your controller setting

Once you pass “70” (models 700 and 950) or “90” (model 900),
the display will reset to “03”.
C. Press the SET button to save the hardness setting number.
D. To recheck the hardness setting number, hold down the SET button
for about 5 seconds.
