  2. Use prescribed pipe sizes as mentioned on the product name plate.
  3. Place the pump center line as close as possible to the water surface.

  4. The free end of the suction pipe fixed above the bottom of the well. Refer Fig. 2, shown below for recommendations:

  5. Use as few pipe fittings as possible in the suction line.

  6. Remove the filling plug and pour water as shown in Fig. 3 below; into the casing till it overflows. Replace the filling plug and tighten it.

    During priming, check the pump suction pipe for leakages.

  7. Ensure that the suction pipe connected to the pump suction flange is horizontal or sloping upwards towards the pump suction flange to prevent air lock. A pipe sloping downwards towards the pump suction flange will result in air lock. Refer Fig. 4, shown below, for the preferred suction pipe orientation.

  8. Ensure pump is primed.
  9. Connect the sewage pumps to the starter and power up the pump.
    • Check the direction of rotation of the motor shaft. If the direction of rotation is in the same direction as that marked on the casing, the connections are right.
    • In case the direction of rotation of the motor shaft does not match the marking on the volute casing, interchange any two lead wires at the starter and confirm the direction of rotation as before.
  10. Electrical Installation
    • Ground the Sewage pump using the two earth screws provided on the leg of the motor body.
    • Ensure electrical joints, if any, are properly and adequately insulated.
    • Connect the cable properly to the starter terminals to avoid loose connections.
    • Factor in low voltage operation while selecting cable size.
  11. Power cable connection to non clog sewage pump.

    Refer Fig. 5a and 5b, shown below, for connecting the lead wires to the Terminal Board of Single and Three Phase Non Clog Sewage Pumps.
