The electric water pumps shall be lifted up and laid down vertically, and the dipping depth shall be more than 2 meters but no more than 35 meters. Four meters or more must be maintained between the electric pumps and the well bottom so that the sundries won't be involved.

Moreover, the electrode on the under-well level controllers must be one meter or more above the electric pumps to ensure that the electric pumps are complete dipped in the water when running. Security guard systems will automatically work when the voltage is too low, the current is too small, the pipe is frozen, or the impeller is blocked. Please cut it off the spare cables, and the cables must be reliably grounded.
