?? Critical Warnings & Safety

ELECTRICAL HAZARD: Installation involves wiring into low-voltage automation control boards. Failure to follow proper electrical safety protocols can result in equipment damage or electric shock.
ERRATIC READINGS: A sensor that is partially shorted or has corroded wire leads will provide false temperature data, potentially causing the heater to run indefinitely or prevent solar systems from engaging.
MOISTURE INTRUSION: Ensure the water sensor is perfectly sealed in the pipe. A leak at the sensor port can lead to flooding of the equipment pad and damage to nearby electronics.
?? Professional Installation Tips
  • Water Setup: Drill a 3/8-inch hole in the pipe between the pump and filter. Insert probe and secure with a stainless steel hose clamp.
  • Air Setup: Mount the probe in a shaded area. Keep away from direct sunlight, air conditioners, and pump motors to avoid "false heat" readings.
  • Solar Setup: Fasten the sensor next to unglazed panels. For glazed panels, place it between the collector and the glazing.
  • Resistance Check: Use a multimeter to verify health. At a water/air temperature of 77�F (25�C), the sensor should read exactly 10,000 Ohms.
PROCEED WITH CAUTION: It is highly recommended that this product be installed by a qualified pool service technician to ensure proper system integration and safety.
NON-OEM REPLACEMENT: This is a high-quality compatible replacement part and is not manufactured or sold by Pentair. All brand names are used for reference purposes only.
