Installation Notes：
If you find that the oil pump cannot start or the speed is low, please check and solve the problem from the following aspects:
- Whether the impurities in the oil tank have been completely removed.
- Replace the filter with a new one.
- Check whether the positive and negative terminals of the power supply are correct.
- Make sure the air inside the pump is removed.
