It is the same as the bedroom a Schwintek In-Wall slide system. Plenty of videos on the manufacturer’s website or search on YouTube. That is where their videos are hosted. If I remember correctly you disengage the motors and you have to manually push in. I don’t know if you could do it alone and hope I never find out. This is for a 2016 and assume yours is the same. Also maintenance videos there as well.

Hmm. That was not the answer that I expected. There are no typical schwinteck aluminum rails as on the bedroom slide? But I think it is the same manufacturer (Lippert) but the “Electric Through the frame slide-out” if I’m right there should
be a way to retract them manually. See page 34 in following manual. https://lci-support-doc.s3.amazonaws...0001573-10.pdf
