  • Universal style: Each heat pump manufacturer has different plugs, so you may need a to cut and join the two wires. Polarity does not matter.
  • Blue part in photos is a thread protector they sometimes come with but is not used.
  • Ensure correct orientation & water flow when fitting so water flow engages the paddle.

Most fail due to water balance issues or bromine.

Test using a multimeter for Normally Open to Closed-Circuit when paddle is engaged.
