5. Smart pH will maintain the pH levels either increasing pH using base or decreasing pH using acid of your water system automatically The Smart pH will only increase or decrease the pH The Smart pH is recommended for use with a chlorine generator or an erosion type feeder You can also use the Smart pH when hand feeding liquid chlorine base or muratic acid as the chlorine will increase the pH and the acid will decrease the pH The Smart pH can also control CO gas systems with the same efficiency as an acid feed controller For specific information on installation refer to documentation supplied with CO chemical feeder RELAY The Smart pH has one relay module to control the pH levels SENSORS Smart pH can measure inputs from one pH sensor VOLTAGE Smart pH can only work on an input voltage of 110 VAC CHAPTER 2 INSTALLATION 2 1 PREPARATION Receipt Inspection Upon receiving the controller from shipping check the carton carefully Report any dam aged items directly to the shipping company Examine the package content list below and verify that all items are present Please contact your local Acu Trol dealer if any items are missing or have been damaged Use care when unpacking equipment to avoid damage or loss of small parts 2 2 PACKAGE CONTENTS Smart pH Controller Mounting Hardware pH Sensor T Assembly pH Sensor Flow Switch Assembly gt B E 0 Kt Smart pH 4 INSTALLATION SUMMARY
