  • Verify the part number printed on your existing panel matches 6600-509 before ordering
  • Check the cable connector on your current panel — pin count and connector type must match
  • Inspect the control pack (inside the equipment bay) to confirm it is compatible with this topside panel
  • If your spa is under warranty, contact Jacuzzi directly before replacing OEM parts
