Awesome, I'm glad that got you up and going. I'm surprised support wasn't aware of that link.

Final update: today, I was able to open the electronics box using the Core ONE L instruction link sent by @darkmattermaker. Indeed, the cable length is more than enough. I have sent an email to Prusa to point out that the QR code on the leaflet points to the Core ONE instructions, not Core ONE L.

The third screw that was not supposed to be removed appears to be related to the power supply. Since the screw went back in, I'm assuming / hoping that everything is OK now.

What directions did you follow? The guide here?

The images in there seem to show plenty of length in the cable to reach the indicated fan header.

Ooh! The QR code on the leaflet included with the kit pointed me to a different page - so there *is* a page for the C1L now! Thanks, I will give that a try and report back!

edit: support asked me to remove all 3 screws… the C1L page says “do not remove!!”… Now I’m slightly worried :-(

I followed the online instructions mentioned above - no problem here as it is a very detailed and clear instruction

I hear you ... opinions only BUT this is - IMHO - the very reason kits are such a great thing. Industrial training can be absurdly expensive, and a "kit" comes with a free, full-blown, 100 % down-to-the-bottom "do-or-die" training lesson that appears on no budgetary sheet.

The assembly instructions for the Advanced Filtration kit are not yet updated for the CORE One L.

I spent a lot of time with support (very nice and patient!), trying to figure out where to plug in the fan cable. The electronics box is different from the regular CORE One.

The improvised procedure for opening the electronics box did not work for me; I did not feel comfortable messing around with the belts and pulleys to reach the plastic lockers. I could not turn them using pliers without risking damage to the printer, so we aborted the attempts - leaving me with a mounted filter, but disconnected fan.

The supplied hex key does not fit the M5 screws. The chamfered plastic holes in the fan do not properly grip the screws; the plastic in the fan holes stripped immediately so I had to replace it with some longer bolts with retention nuts.

All in all, I do not recommend purchasing the Advanced Filtration kit until proper and practical instructions become available for the C1L
