⚠️ Critical Warnings & Safety

SCALDING HAZARD: Improper installation can lead to water temperatures exceeding 108°F, which may cause serious burns or permanent injury.
IGNITION FAILURE: A faulty thermistor provides incorrect data to the control board, potentially causing the heater to fire incorrectly or display "HI" / "E02" errors.
ELECTRICAL HAZARD: Always disconnect the circuit breaker and shut off the pump before service. Opening the manifold under pressure will cause high-velocity water spray.
💡 Professional Installation Tips
  • Diagnostic: If your heater says "HI" while the water is ice cold, the sensor or yellow wire is likely damaged.
  • The Multimeter Test: Set your meter to Ohms; the sensor should read exactly 10,000 at 77°F (25°C).
  • Seal the Threads: Wrap the brass threads with Teflon tape before screwing into the manifold for a watertight fit.
  • Storage: Keep spare sensors in a dry place between -10°C and +40°C away from ammonia or sulfur gases.
PROCEED WITH CAUTION: High-temperature heating components require precision handling. Professional installation by a licensed pool/gas technician is recommended.
CALIFORNIA PROPOSITION 65 WARNING: This product may contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.
