Self-priming pump installation and precautions: 1. First check everywhere bolt loose, the power cord and the plug is intact, the motor insulation resistance should be greater than 2 megohm. 2. In order to prevent electric shock accident, it is necessary to install the corresponding safety measures such as earth leakage circuit breaker or electric shock safety device, etc., and to conduct reliable earthing. 3. The operating voltage of pump should be used in the range of 5% of rated voltage and -12% Will reduce the life of the motor or burn out. Stainless steel pump electric pump as far away from the power supply, the power transmission line should be appropriately bold, otherwise it will use the voltage drop and can not run. 4. Close the power switch, the pump idling about 2 minutes to see the start, the operation is normal, the steering is correct. 5. Fix the pump body with steel pipe or rubber tube (must not be too soft to avoid drawing flat). Connect the inlet and the bottom valve.

Clean water centrifugal pump use and automatic suction pump for the first time before the use of self-priming pump storage tank should be filled with water, electricity can not automatically after a few seconds out of water, the future does not require irrigation. 7. Since the pump and automatic self-priming clear water pump tube for the first time before use, it is necessary to fill the water tank filled with water, electricity can not automatically after a few seconds out of water, the future does not require irrigation. 8. Use, the motor should be kept dry, pay attention to the water level down, the bottom valve can not be exposed outside the water. When the temperature is below 4 â—‹ C. Antifreeze should be done, so as not to freeze the pump body. 9. If not for a period of time, should drain the net water pump (self-priming pump and automatic pump down water storage tank), the main components scrub clean, coated with anti-rust oil, placed in a ventilated and dry place for future use.
