I'm not sure I understand your question. If you have the manual (I can provide a link if you don't) the draining procedure is on page 42. If you want to drain the lines below it you'll need to have drain valves in the piping below it. The best option if this will be exposed to freezing temps is to blow the lines below it out with an air compressor
Do you have more questions?
