The LG manual is marginal in that regard.

The Sanyo website has some good dealer/tech training info & videos.

Maybe LG has something similar on their commercial website.?.
From what I've read on the web, there are only two things to maintain on a mini-split.
1. The indoor unit's filters need to be kept clean.
2. The outdoor coil must be free of leaves etc.
I wonder what the life span is going to be.. I've read 8-12 years.
I suspect it might be longer, since early mini-splits were not inverter type.
I just recycled a 6,000 BTU AC that was still working. Had it since 1968..
It was used a lot, up until about 1985. My big 18,000 Chrysler Air Temp
window unit had been working since 1973. It had an accident about 5 years ago..
