1. (1)After the submersible pump is installed, check the insulation resistance and three-phase conduction from the switch again, check whether the instrument and the connection of the start equipment are wrong, if there is no problem, the trial machine can be started, and observe whether the indicator readings of the instrument exceed the rated voltage and current specified on the nameplate after the start, and observe whether the pump has noise and vibration phenomenon, and put into operation if everything is normal.
2. (2)After the first operation of the pump for four hours, the motor should be shut down to test the thermal insulation resistance quickly, and its value should not be less than 0.5 megaohm.
3. (3)After the pump is shut down, it should be started after five minutes to prevent the water column in the pipe from being completely reflowed and causing excessive motor current and burnout.
4. (4)After the pump is put into normal operation, in order to prolong its service life, it is necessary to check whether the supply voltage, working current and insulation resistance are normal regularly. If the following conditions are found, the pump should be shut down immediately to troubleshoot.

1 In the rated condition, the current exceeds 20%.

In order to ensure long-term use of your submersible pump, we strongly recommend that you drain the water in all motor cavities especially in winter to prevent the motor from freezing; at the same time, roll up the cable and tie it well. Store the equipment in a room without corrosive substances and gases, with the temperature below 40 °C. In addition, if you do not use the submersible pump for a long time, be sure to pay attention to rust prevention measures. These simple steps will help you maintain the performance of the equipment and extend its service life.
