【 Weak current College 】 self-priming class installation and notes---Power By 【 China power house network 】

1. first check everywhere there are no loose bolts, power cables and plugs are intact, the electrical insulation resistance should be greater than 2 megabytes of Europe.

2. in order to prevent electric shock, you must install leakage power tap or shock protector and other appropriate security measures, and to carry out reliable earthing

3. pump operating voltage range of use shall be at the rated voltage of + 5%-12% of the room, this will make motor service life is reduced or burned. Electric pump such as the use of land from the power supply, power transmission lines should be bold, otherwise it will use the voltage drop and cannot run.

4. close the power switch, the pump idling 2 minutes viewing startup, operation is normal, the steering is correct.

5. fixed the pump body, pipe or rubber tubes (not too soft, so as not to draw flat), the connection of the intake and bottom valve, foot valve placement must be perpendicular to the horizontal plane, leaving more than underwater, so as to avoid 30Cm suction on the sediment.

6. water use and automatic suction centrifugal pumps for the first time before the tank filled with water, the power of tens of seconds after non-automatic water, later use it without irrigation.

7. Since the Jiqing pump and automatic self-priming pumps tube before first use, the water storage tank filled with water, within the power of tens of seconds after non-automatic water, later use it without irrigation.

8. use the motor should be kept dry, water conditions, bottom valve does not re-appear. When the temperature is below 4 C 2000. The work should be done to prevent Frost crack anti-freeze pump body.

9. If a period of time not to be drained net pump water (self-priming pump and automatic pump out the water tank), wipe the main part, painted with antirust oil, placed in the alternate vent dry place.
