There are teardown guides for all centrifugal chillers, but they are supposed to be controlled documents. If you are asking for a teardown guide and think that’s it, go get some quotes from chiller repair groups in your area. The amount of rigging and tools that are required will far outweigh the savings. I’ve seen the results of inexperience, dropped compressors and personnel hurt. If you are curious, hire someone and request to assist them. It will be a learning experience, seeing what is involved.
Just my opinion, good luck with your decision.
