🔍 Key Concepts

• Manifold center ports: Which ports are labeled or positioned for VAC (vacuum pump) and REF (refrigerant source)? • Hose routing during evacuation vs. charging: How many center ports are available, and what is each one connected to in the illustration? • Difference between sets that let you keep all hoses connected at once and those that force you to move a hose from the vacuum pump over to the refrigerant cylinder.

💭 Think About

• For each manifold, imagine you are first pulling a vacuum on the system. Which port and hose would you be using to connect the vacuum pump? • Now imagine you are done evacuating and ready to charge from a refrigerant cylinder. On which manifold(s) can you simply open/close different valves without moving hoses, and on which would you have to disconnect and reconnect a center hose? • Look closely at the labels and number of center ports: which set has a dedicated port for VAC and a separate one for REF, and which one has only a single center connection that must be used for both tasks?

✅ Before You Answer

• Verify which manifolds have two clearly separate center ports (one marked VAC and one marked REF). • Verify which manifold(s) show only one center connection for both evacuation and charging, meaning the hose must be moved between the vacuum pump and the refrigerant cylinder. • Confirm in the illustration that the low‑side (blue) and high‑side (red) hoses can stay connected to the system in all cases; focus only on what must change between the vacuum pump and refrigerant supply.
