Before you buy — quick checklist

  • Confirm your spa uses a 1 or 2 pump configuration — this board is not designed for 3-pump systems
  • Verify your existing board's revision number and part number before purchasing — photograph the old board label
  • Check that your spa's control pack model is compatible with the 6600-512 board
  • Disconnect all power at the breaker before removing the old board — treat all terminals as live until confirmed dead
  • Inspect wiring harness connectors for corrosion or heat damage before installing the new board — a damaged harness can fail a new board quickly
  • If you cannot confidently identify your control pack model, have a qualified spa technician verify compatibility first

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
