Before you buy — quick checklist

  • Confirm your existing control system part number is 0602-221066-300 — check the label on your current unit
  • Verify your spa is wired for 240V and that your electrical supply matches this unit's requirements
  • Confirm your spa uses a dual-pump configuration (Pump 1 and Pump 2 with 1/2 speed setup) — this unit is not suitable for single-pump systems
  • Check that your spa's topside control and auxiliary accessories are compatible with the In.Xe platform before swapping the pack
  • Take photos of all existing wiring connections before disconnecting anything — this is a combined heater and control unit with multiple connections
