    • 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. rIQKkVtj2p5R4p1C

    • 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.

    • Use the pliers to cut the red and black cables before and after the joint.

    • Screw the new sensor by hand for the initial part.

  6. Pe21RImO1kAFGkeo

    • 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.

    • 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.

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

    • 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.

    • Insert the heat shink tubing on both motor's cables.

  10. QdOUS5UGMuMjihi5

    • 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!

    • 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.

    • Insert the heat shrink tubing.

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

    • 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.

    • Fix the cables using the plastic strap.

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

    • You can now enjoy your updated sensor!
