Refrigerant cylinder during automatic refrigerant charging

All Recorded Causes

Refrigerant cylinder of slave unit 2 is empty

Verify Before Replacing Parts

  1. Confirm the exact Daikin model family and vrv context before acting on a generic code description.
  2. Verify airflow first, then confirm operating pressures and temperature relationship before adjusting charge, since refrigerant cylinder of slave unit 2 is empty.
  3. Look for restrictions, iced coils, or dirty heat-transfer surfaces that can mimic a charge problem, and separately confirm the next candidate on the list.
  4. After the correction, run the system long enough to confirm the vrv fault does not return under normal load.
