- Match full equipment and controller models, refrigerant, region and document revision.
- Use the unit wiring label and OEM specifications. A related brand name or similar cabinet does not prove compatibility.
- Isolate power, secure against restart and prove it absent before resistance tests or repairs. Follow approved capacitor and inverter discharge procedures.
- Preserve safety interlocks and refrigerant mitigation. Stop on unsafe conditions or suspected leakage.
