✅ Check Before You Order
- 📍 Check the model on your existing spa pack label (inside the equipment bay) and match it to this listing, not the brand name on the tub.
- 📍 Check your topside against the Compatible Topside Panels list above. If you are keeping your existing panel, it needs to be on that list.
- 📍 Turn off the power at the breaker before any work. If you are not confident with spa wiring, use a qualified electrician.
- 📍 Not sure? Send us photos of your pack label, board and topside, and we will confirm the right part.
