When we obtained an 07C210P I thought the water diagram was hard to understand, and maybe not correct. However, one day I decided to run water from either water tank with the pump and open and close every valve to see just where water comes from and goes to. When I was done I understood the water diagram and did not find any errors. While doing this I used a permanent marker and labeled lines I could see as either hot or cold and added direction arrows. Going through this effort made me understand the system.
