  • Verify whether your system is single-pump — this control panel is designed for single-pump setups
  • Check your local electrical code requirements before replacing a control pack — permits may be required
  • Inspect all wiring harnesses and connectors for corrosion or heat damage before installation — replace damaged wiring before fitting the new pack
