Stopping

1. Gradually close the discharge pipe valve and cut off the power supply;
2. Close the inlet valve;
3. If the ambient temperature is below 0 ℃, the liquid inside the pump should be drained to avoid freezing and
cracking; /自启动永磁同步电机
4. If the pump is stopped for a long time, the liquid inside the pump should be drained and regularly maintained.
