Winterizing Columbus mf381fl

My father in law just purchased a new 2016 Columbus cmf381fl. On the outside control panes there are valves to turn for winterizing but no Inlet for the antifreeze. For the winterizing function on the control panel, does that bypass the hot water tank or will he need to find the valves in another location?

The factory sent me a manual by email that explains how the system works. Google Nautilus P1 Manual. It should come up. If not, call the factory.
