1. Before the use of self priming pump check whether there is no loosening of bolts, power cord and plug is intact, the motor insulation resistance should be greater than 2 mb.
2. To prevent electric shock accident, must be installed leakage circuit breaker or electric shock security guards and other appropriate security measures, and to carry out a reliable grounding.
3. Pump working voltage range shall be at the rated voltage of +5%, the -12%, otherwise it will make the service life of the motor is reduced or burned out. Such as the use of electric pump power from far, power transmission line should be bold, otherwise it will use the voltage drop to run.
4. Industrial self-priming pump on the power switch, the pump idle for about 2 minutes, view startup, operation is normal or not to is correct.
5. Fixed pump body, with steel tube or a rubber tube (not too soft, so as not to suck flat), connected with a water inlet and a valve, valve placed must be vertical to a horizontal plane, underwater 30cm above ground, in order to avoid ceiling on sediment.
6. Self priming water pump and self priming sewage pump for the first time before use, to fill the pump body full of water, after tens of seconds of electricity can be automatically water, after the use of no irrigation.
7. When in use, the motor should keep dry, pay attention to the water level decline, not exposed outside the valve. When the temperature is less than 4, C. Should do the antifreezing work, to avoid the cracking of pump body.
8. If a period of time need not, should row net pump water (self-priming pump and automatic pump drained water storage tank water), the main parts of the scrub clean, coated with anti rust oil, placed in ventilated and dry place spare.
