There's the old High and Low side.. Right??

Well, it sounds right... In the diagram at the top, there is a legend for Wide Tube Service Valve and Narrow Tube Service Valve. I guess they're avoiding High Side & Low Side because it depends on the direction of flow.
So yes, your scheme sounds reasonable. Probably should use the gauge with the highest range.
Make sure the needle valve on the manifold is closed.
Have you asked your Sanyo support tech for the proper proceedure?
