Do you have a question about the ECO20110-1 and is the answer not in the manual?

Questions and answers

Our salt level is 3600-3700 ppm per a salt pool test strip. The system runs for a few minutes and then the low salt indicator comes on. The manual states that the level should be around 3000-3500 ppm. What actually reads the salt level in the system? What part?
