I think that there's not a lot of "technical requirements" on slide maintenance. They are, for the most part, a fairly simple system, certainly not nearly as complicated as the space shuttle or a modern airplane. That said, ignoring the manufacturer's (Lippert) suggested maintenance requirements probably won't have nearly the impact on the slide's reliability as ignoring Boeing's maintenance requirements do on the reliability of a 747 airplane.

In other words, not following Lippert's advice probably won't have a significant impact on whether your slide lasts 4 years or 40 years, but with that said, here's what Lippert printed in their "Electric Slide Manual":

"Mechanical Maintenance
Although the system is designed to be almost maintenance free, actuate the room once or twice a month to keep the seals and internal moving parts lubricated.
Check for any visible signs of external damage after and before movement of the travel trailer.
NOTE: For long-term storage: It is recommend that the room be closed (retracted)."

Just how important is the above? I dunno, but it's what the manufacturer recommends. YMMV
