Depending on the situation, the refrigerant running sound or the
sound of a magnetic solenoid valve may rise during this
operation.
The following items are automatically checked:
- Check for incorrect wiring
- Check if stop valves are open
- Check of refrigerant charge
- Automatic judgement of piping length
