Probe Maintenance
The probes must be clean and free from oil, chemical deposits and contamination to function properly. After saturation in pool or spa water, the probes may need to be cleaned on a weekly or monthly basis depending on bather load and other pool specific characteristics. Slow response, increased need to calibrate pH, and inconsistent readings are indications that the probes are in need of cleaning.
To clean the ORP and pH probes, run the Clean Probe Wizard within the Settings Menu on the Aqua Rite Pro or the Maintenance Menu on the Pro Logic. This Wizard will walk the user through the probe cleaning process. Answer the questions when prompted, and follow the instructions for proper cleaning.
To clean the probes without running the Wizard, turn off input power to the Aqua Rite Pro or Pro Logic. Disconnect the probe connectors from the communication box, unscrew the probe and carefully remove them from the Probe Cell. Clean the reference junction (the white ring at the bottom of the probe body) with a soft toothbrush and regular tooth paste. A household liquid dishwashing detergent may also be used to remove any oil. Rinse with fresh water, replace teflon tape on threads and reinstall probes. If properly cleaned probes continue to provide unstable readings or require excessive calibration, the probes should be replaced.
