Before you buy — quick checklist

  • Confirm your existing control system part number is exactly CS6P52Y-US-4 — do not substitute based on appearance alone
  • Verify your spa is wired for US voltage configuration before ordering
  • Check that your spa uses HydroQuip Y Series lo-flo technology — this system is not interchangeable with standard-flow HydroQuip platforms
  • Document all error codes currently displayed before beginning the replacement so you can verify the fix post-install
  • Confirm your spa's current wiring harness connectors are compatible with this control system before disconnecting anything
