DISC SELECTION
DISC SELECTION WS-40/80
The amount of hardness removed (in compensated gpg) will be based on the amount of brine and the meter disc selected.
1.Determine the compensated hardness. This requires a hardness test and an iron test on raw water at the application site. Compensated hardness is calculated by multiplying the ferrous iron (in ppm) by 3 and adding it to the grains of hardness.
2.To test the water supply, use the water analysis test kit available through Pro Products Inc. The recommended kit is #2401 Field Analysis Kit. To order the test kit contact Pro Products at
3.Determine the salt setting. The salt setting is determined by taking the compensated hardness (calculated in step 1 above) and using the specification table for model
4.Verify the float cup setting. Use specifications for the
