Instruction to install Automatic Ejection Device

1. This underwater motor pump is originally designed to be straight upward and should not be laid down on a side or shocked while transporting.
   
   
2. Transport the pump not by pulling out an attached electric waring, but by grabbing handles.
   
   
3. Upon receiving the pump, piease check on the insulation ststus followed by carefully inspecting whether the machine matches up with specifications, such as pumping level and quantity, rotational speed, output, voltage, frequency, and other types.
   
   
4. Check for any damages on wire coating from transportation as well as anymissing parts, bolts, and nuts.

Installation and Test Drive Considerations

1. Firstly, tie up the pump handle and the other side to a secure object with rope and chain.
   
   
2. Use blocks or other stable plate on a bit higher level to support the pump if the mounting site is exposed of collapsing, and link the pipe perpendicular to the pump.
   
   
3. Do not use the cap tire cable attached on the pump in order to move it in the vertical direction. Use only the rope tied on a handle of the pump. Puling the cable might cause disconnection or shorting of electric wiring for damage, or may let water inflow to break the insulation.
   
   
4. Do not place the cable -end in the water or a humid place.
   
   
5. Motor is designed to run under water and should not be operated on the ground.
   
   
6. Install the pump in a vertical position, and be especially careful when mounting a out -flowing pipe.
   
   
7. Use a correct electric wire a occurs when lengthening the wire connection. Check to see if the connect is secure and insulation of the wire is safe in a humid place to avoid an electric leskage.
   
   
8. Do not bury a cable in a concrete structure to avoid an electric leakage.
   
   
9. An optional automatic ejection device is available in case of installing the pump in a pit area for later repair.
   
   
10. Minimum level of the water reservoir should cover up the case, and at least 30cm above the top of case.
    
    
11. A cutter pump is the pump which shreds solid matters to prevent any clotting. However, it is recommended to use a first level filter with a net narrower than the strainer for the sewage including larger particles than it' shredding capability.
    
    
12. Harsh bending on out -flowing pipes may reduce the water transport amount. Thus it is recommended to more of straight piping.
    
    
    

Test Drive

1. Remove any steal and rocks that hinders the inlet in the pit.
   
   
2. Check if the correct voltage is used and the state of the fuse capacity and connectivity.
   
   
3. Confirm if the output voltage is within 10% of the voltage specified.
   
   
4. Check the rotational direction of the pump. In case the motor is rotating in the reverse direction, change two of U,V and W connection."
   
   
5. Green line is for grounding and should be installed.
   

Connection Type

Waring of the pump is designed to handle 220V and 330V. When chainging the voltage, use staler cable following the instruction below after disassembling starting box as well as a motor brecket, and the voltage cannot be changed, and a separate order has to be made for the 440V and 480V (Miss-installation of packing may cause a leakage with a danger of an electric shock.)
