isolating heat pump

I am in the process of replacing my plumbing due to too many fittings by the pb and needing a new pump. He did not isolate the heat pump initially. Should I have bypass or isolation valves put in the plumbing circuit when I hook it up? If so when would I need to turn it off?

Thanks!
