Technician Check
- Confirm the complete indoor-unit model number and rated capacity.
- Isolate power before inspecting the PCB or DIP switches.
- Record the existing SW1-1, SW1-2, SW1-3, SW1-4 and SW2-1 positions.
- Compare the existing factory setting with the applicable capacity row above.
- Do not change the capacity setting on site.
- Where the model is one of the special applications highlighted above, verify the model-specific note before drawing any conclusion from the switch pattern.
