Use

After the user purchases the qualified product, the user must read the instruction manual in detail and operate it in accordance with the conditions specified in the manual. Because the sewage pump products are assembled by the motor and the water pump, due to improper use by the operator, electric shock may occur, resulting in personal injury or death. Therefore, special attention should be paid to the following safety requirements:


1. When using the product, check whether the cable is damaged or broken, and whether the inlet seal of the junction box cable is intact. If it is found that there is a possibility of leakage and poor sealing, it should be handled properly.


2. It is strictly forbidden to impact and pull the electric pump to pull out the cable.


3. The power supply line must have leakage protection devices.


4. The power must be cut off during installation or maintenance, and live working is strictly prohibited. In addition, when using the product, it is necessary to select the working conditions reasonably to extend the service life. It is forbidden to adjust the limited current of the protection switch at will to avoid product damage caused by overload.


Maintenance

The user should perform maintenance according to the requirements of the product instruction manual. Maintenance problems should be solved by personnel with professional skills and relevant knowledge. In particular, it should be noted that after the product has been used for a period of time, it should be checked whether the electrical insulation meets the requirements and whether the grounding is firm and reliable.
