Automatic Control Box - Rated Horsepower Matching Protection, Weather-resistant Design For Optimal Functionality

* Each pump with rated horsepower should match the automatic control box with the same horsepower.
* Do not expose the control box to the strong sunlight or get it wet by rain. Put it in a well-ventilated place, and avoiding strong shock.
* The live wire of three-phase power should go through on-off switch, the zero wire can go through directly.
* Fuse requirement: fusing current = rated current X (l.5 ~2).
* The water-level control of headwaters and water tower needs only an electrode conducting wire and a return conducting wire. The upper and lower limits of the water level can be differentiated by special "level divider". One side of it has a conducting wire, which should be connected with the terminal of "well electrode" or "tower electrode"; the other side has two conducting wires, of which the short one is the water-level upper limit conducting wire, while the long wire is the water-level lower limit conducting wire. Both conducting wires can be connected with electrode detector Respectively and be put at the required water levels. If the electrode cannot reach the required depth, the conducting wire can be lengthened. The return electrode must be placed under upper and 1ower electrodes.
* Short circuit shou1d be avoided between various conducting wires, electrode, and the wall of the well or tank.
* Well Electrode could not be installed if water is sufficient, and
the water level wil1 never be lowered to the intake of the pump,
