How to Calibrate a Hayward Goldline Aqua-Rite or Swim Pure Plus Pool Salt Chlorine Generator
Step 1: Adjusting Salinity (Salt) level
Before the chlorine generator can be calibrated correctly, the salinity, or salt level in the pool water, will need to be at the correct level. For these systems, it should ideally be between 3200-3600 ppm (parts per million). This can be tested using a salt test meter or salt test strips. I personally use the by SafeDip. This meter is very accurate and also measures pH and chlorine levels. Solaxx MET01A Digital Test Meter
If the salt level is low, or no salt has ever been added to the pool, the salinity level will need to be increased and allowed to circulate for 24 hours before starting the calibration process. It is also important for any salt chlorine system that the stabilizer level in the pool water is between 50-70 ppm.
Step 2: Locating the Calibration Screen
Once the salinity is adjusted to optimal level, the calibration process can begin. With the pump running and unit set to "Auto" position, press the "diagnostics" button 5 times. The screen should display "- 0"
Step 3: Setting the Salinity Level
This step can get tricky and may need to be repeated. While on the calibration screen and with the pool pump still running, push the "Auto" switch down to the "off" position for 2 seconds. Now push the switch back up to the "Auto" position again. Wait approximately 10 seconds (you will hear the relay kick on). The calibration screen will start counting down from a higher salt reading than what the actual level in the pool water is. Once you see your salinity level, push the switch up to "super chlorinate" and then immediately back down to the "Auto" position. It is now calibrated. Press the diagnostics button several times until you see your salinity level displayed.

Step 3 takes some practice as it counts down VERY quickly. For example, if the salinity level in the pool water is 3300 ppm, when the switch is pushed from "off" position up to the "Auto" position, after 10 seconds it will display a set of numbers that start going down immediately. It might start at say, 4800 (could be higher or lower). Push the switch to "super-chlorinate" when it hits 3300 ppm. Then quickly push back down to "Auto."
