Which of the following statements is true concerning the illustrated gauge manifold set? GS-RA-01

Correct Answer: Option D — Closing the valve labeled "G" isolates the hose labeled "H" from the hose labeled "J".

On a standard four-valve or two-valve manifold set, closing the low-side manifold hand valve physically blocks fluid communication between the center utility charging hose and the low-side service hose connected to the system.
