Marco UP Series Electric Pump Electronic Sensor Replacement

Wat je nodig hebt

  1. Marco UP Series Electric Pump Electronic Sensor Replacement, Prepare the tools: stap 1, afbeelding 1 van 1
    • The additional sensor with the joint and the heat shrink tubing is available as a replacement kit on www.marco.it .

    • Kits are only available as a registered user, and can be seen for each pump in their dedicated tab on the page.

  2. Marco UP Series Electric Pump Electronic Sensor Replacement, Cut the plastic tie: stap 2, afbeelding 1 van 1
    • Free the cables by cutting the plastic tie.

    • Don't cut the cables that connect the sensor to the pump.

    • Dont' damage the cables' insulation while cutting the plastic tie.

  3. Marco UP Series Electric Pump Electronic Sensor Replacement, Cut the joint between the sensor and the motor: stap 3, afbeelding 1 van 2 Marco UP Series Electric Pump Electronic Sensor Replacement, Cut the joint between the sensor and the motor: stap 3, afbeelding 2 van 2
    • Use the pliers to cut the red and black cables before and after the joint.

  4. Marco UP Series Electric Pump Electronic Sensor Replacement, Remove the old sensor: stap 4, afbeelding 1 van 2 Marco UP Series Electric Pump Electronic Sensor Replacement, Remove the old sensor: stap 4, afbeelding 2 van 2
    • Use the 17mm wrench to unscrew the sensor.

  5. Marco UP Series Electric Pump Electronic Sensor Replacement, Screw in the new sensor: stap 5, afbeelding 1 van 3 Marco UP Series Electric Pump Electronic Sensor Replacement, Screw in the new sensor: stap 5, afbeelding 2 van 3 Marco UP Series Electric Pump Electronic Sensor Replacement, Screw in the new sensor: stap 5, afbeelding 3 van 3
    • Screw the new sensor by hand for the initial part.

  6. Marco UP Series Electric Pump Electronic Sensor Replacement, Tighten the sensor: stap 6, afbeelding 1 van 1
    • Use the wrench to tighten it in place.

    • Don't over-tighten the screw!

    • Don't add PTFE tape on the screw: there's already an o-ring to seal the connection and it may cause problems to the non-return valve (check valve) underneath.

  7. Marco UP Series Electric Pump Electronic Sensor Replacement, Check how long you want to strip off the cable: stap 7, afbeelding 1 van 1
    • Use the joint as a reference on how much you need to remove.

    • Keep in mind that you want to have as much wire inside as possible, but you want to avoid that the peeled wire exits the joint.

    • Use the cutting plier or (if you have it) the stripping plier to remove the sheath.

    • Try to be careful: you don't want to cut the wires inside, especially on the larger pumps.

  8. Marco UP Series Electric Pump Electronic Sensor Replacement, Insert the heat shrink tubing: stap 9, afbeelding 1 van 3 Marco UP Series Electric Pump Electronic Sensor Replacement, Insert the heat shrink tubing: stap 9, afbeelding 2 van 3 Marco UP Series Electric Pump Electronic Sensor Replacement, Insert the heat shrink tubing: stap 9, afbeelding 3 van 3
    • Insert the heat shink tubing on both motor's cables.

  9. Marco UP Series Electric Pump Electronic Sensor Replacement, Insert the metal joints: stap 10, afbeelding 1 van 1
    • The cable has to be totally inside the metal joint: if you have a longer peeled cable, cut it a little to have it aligned as in picture.

    • Don't insert the plastic sheath inside the metal joint: it worsens the connection and may cause overheating in the large pumps!

  10. Marco UP Series Electric Pump Electronic Sensor Replacement, Press the metal joint: stap 11, afbeelding 1 van 3 Marco UP Series Electric Pump Electronic Sensor Replacement, Press the metal joint: stap 11, afbeelding 2 van 3 Marco UP Series Electric Pump Electronic Sensor Replacement, Press the metal joint: stap 11, afbeelding 3 van 3
    • Start on the motor side, and press the metal joint on the cable.

    • To have a stronger force in closing the joint use the internal part of the plier, as showed in the picture.

    • Proceed with by inserting the other end, the short cable coming from the sensor.

    • Repeat the process also for the other cable.

  11. Marco UP Series Electric Pump Electronic Sensor Replacement, Cover the metal joints with the heat shrink tubing: stap 12, afbeelding 1 van 3 Marco UP Series Electric Pump Electronic Sensor Replacement, Cover the metal joints with the heat shrink tubing: stap 12, afbeelding 2 van 3 Marco UP Series Electric Pump Electronic Sensor Replacement, Cover the metal joints with the heat shrink tubing: stap 12, afbeelding 3 van 3
    • Insert the heat shrink tubing.

    • Make sure that it covers perfectly the joint (it must be centered!) on both ends .

  12. Marco UP Series Electric Pump Electronic Sensor Replacement, Heat the tubes: stap 13, afbeelding 1 van 2 Marco UP Series Electric Pump Electronic Sensor Replacement, Heat the tubes: stap 13, afbeelding 2 van 2
    • Heat the tubes until they shink on the joint evenly.

    • Don't heat too much: you may melt the cables.

    • If you don't have a heat gun, you may also use a lighter, but don't touch the plastic with the flame: keep some distance.

  13. Marco UP Series Electric Pump Electronic Sensor Replacement, Loop the wires: stap 14, afbeelding 1 van 3 Marco UP Series Electric Pump Electronic Sensor Replacement, Loop the wires: stap 14, afbeelding 2 van 3 Marco UP Series Electric Pump Electronic Sensor Replacement, Loop the wires: stap 14, afbeelding 3 van 3
    • Loop the wires as shown in the pictures.

  14. Marco UP Series Electric Pump Electronic Sensor Replacement, Add the plastic strap: stap 15, afbeelding 1 van 3 Marco UP Series Electric Pump Electronic Sensor Replacement, Add the plastic strap: stap 15, afbeelding 2 van 3 Marco UP Series Electric Pump Electronic Sensor Replacement, Add the plastic strap: stap 15, afbeelding 3 van 3
    • Fix the cables using the plastic strap.

    • Cut the excess of the plastic strap using the cutting pliers.

  15. Marco UP Series Electric Pump Electronic Sensor Replacement, You're done!: stap 16, afbeelding 1 van 1
    • You can now enjoy your updated sensor!
