Specification: Item Type: Submersible Pump Model: CSP550C Material: Plastic Power: 550W Flow Rate: 11500L/h Maximum Head: Approx. 8.5meter / 27.9ft Maximum Depth: Approx. 7meter / 23ft Cable Length: Approx. 10meter / 32.8ft Package List: 1 x Submersible Pump 1 x User Manual 1 x Elbow Tube Note: 1. The submersible pump cannot be dehydrated, test run under anhydrous conditions, the time should not exceed 5 minutes. During the pumping process, if the water level continues to drop, be careful not to allow the pump body to work above the water surface. 2. The submersible sewage pump cannot be restarted immediately after it is stopped, can only be started after the water in the pipe has returned to completion. If no water can flow out after starting, stop the machine immediately to find out the cause and eliminate it. 3. It should be used near the specified head; 4. When the submersible pump is placed in the water or raised to the surface, the lifting rope must be pulled, and the cable must not be pulled. If you want to transport, disassemble or overhaul, you should cut off the power first. 5. When the submersible pump is submerged in the water, it should be lifted vertically, not lying horizontally, let alone sinking into the mud. 6. Submersible pumps should not be started frequently, and should not be used for irrigation or drainage of water or muddy water with high sand content. When in use, the outside of the pump can be covered with bamboo net or barbed wire to prevent weeds from blocking the grid of the submersible pump or jamming the impeller of the pump. 7. After starting up, if the impeller reverses (the water output is greatly reduced or no water is discharged), the machine should be shut down immediately, and any two phases of the three‑phase core wire in the cable should be exchanged to make the CW water out.
