Heater element carrier. Suits Davey / Spaquip Spa Power 500A and 500A Mk2 electronic spa controllers. Does NOT suit older Spa Power 54500 (500) controllers.
The element screws through this part, and the optical water sensor screws into the small thread. The heater tank body o-ring seats around the outside of this part.
This carrier does NOT suit:
- Spa Power 500 / 54500 which use a differently threaded water sensor (this carrier PLUS a new water sensor can however be used on 500 / 54500 systems)
- Classic / Classic Plus electric heaters which require a brass threaded nipple for the pressure switch connection
