Points for attention before starting equipment:
- Check the insulation condition of the stator winding with a 0-500V meter before starting the water pumps.
- Don't connect the electric wire of the water pump with the power source without any protective device (which may lead to the burning of the motor due to open-phase and overload). Refer to the connection method of the submersible pump. (See Page 9 for details).
- Check whether the grounding wire is earthed properly.
- Close the gate valve of the outlet pipeline and start the motor. Under the circumstance that the gate valve of the outlet pipeline is shut, the pump can not operate over 3 minutes continuously. Monitor the motor current by switching on the gate valve and control the current within the rated range, and check whether the pressure of the pressure gauge and the operation of the pump are in normality, and refer to the trouble shooting sheet to remove in case of abnormality.
- Submerging cable sockets of the motor into water is prohibited
- Warning:The water pump shall not be moved without turning off the power source. Humans shall not touch the water source where the pump is located when pumping water to prevent electric shock accidents in case there is no current leakage protective device.
