Compatibility and use
This sensor is built to work with Sta-Rite Max-E-Therm pool heaters. It functions as a like-for-like replacement for the original part, allowing you to maintain a stable sensing path without extensive rewiring.

Maintenance and care
After installation, conduct periodic inspections of the sensor area and any wiring harness to detect signs of wear. If readings drift or alarms appear, consult your service guide and consider rechecking the sensor integrity as part of routine maintenance.
