🔍 Key Concepts

• Flow path from the center charging hose to the low-side service connection • Which manifold valve positions keep the high side isolated while allowing flow only into the low side • Safety reason for charging vapor into the low side only (avoiding liquid slugging of the compressor)

💭 Think About

• On each option A–D, trace the orange arrows: from the center port, does refrigerant go only to the low side, or also to the high side? • Which drawing shows the low-side valve open to the center hose while the high-side valve remains closed and there is no cross‑flow between low and high? • If you were actually charging a running system as vapor, which configuration would best prevent liquid from entering the compressor through the high side?

✅ Before You Answer

• Verify which option shows one valve open to the center hose and the other valve fully closed. • Confirm that, in your chosen option, no arrows indicate flow between the low and high sides of the manifold. • Make sure the refrigerant flow path is: cylinder → center hose → low-side gauge port → low-side service connection, with the high side isolated.
