Route the bowden tubes down and run them through approximately 1-2" of the mesh loom as shown.

Loosen the PTC adapter in the top of the hot end EXACTLY 2 rotations. (This is the aluminum part on the top of the hot end that has two wrench flats.) You can get this loosened with a pair of need-nose pliers if you do not have a printed PTC tool

Loosen the PTC Adapter ONLY 2 Rotations.

Slide a lanyard clip onto the bowden tube. Then rest the nozzle down against the build plate (or on a solid surface if the HE280 is removed from the machine)Seat the PTFE tube down in the hotend as far as it can go. Be sure to push hard to get it seated.

While maintaining downward pressure on the PTFE tube, tighten the PTC adapter slowly. Ensure that the heat sink, and heater block are not rotating while you are tightening the PTC adapter.

The PTC Adapter should tighten 2 full rotations (the amount you loosened it).This will cause the black ring in the top of the PTC adapter to rise up as its teeth engage the PTFE tube.

Insert the lanyard clip in the PTC adapter (under the black ring).

If you removed the hotend from the arms for the above operation, reinstall it now.
