🔍 Key Concepts

• Flow path of refrigerant during normal operation (from receiver through king valve, through system, and back to compressor) • Purpose and typical location of suction service and discharge service valves on a compressor • Safety considerations when introducing (charging) refrigerant into a system – especially avoiding liquid slugging of the compressor

💭 Think About

• When you charge refrigerant into the system, do you want it to enter on the low‑pressure side or the high‑pressure side of the compressor? Which valves control those sides? • If you leave certain compressor service valves open while charging, what risk does that create for the compressor cylinders? • Think about which valve is normally used to isolate the receiver from the rest of the system when adding or removing refrigerant.

✅ Before You Answer

• Identify which valve is directly on the liquid line from the receiver (king valve) and what position it is usually in when charging • Confirm which valve(s) connect directly to the compressor suction and discharge ports • Verify which line (suction or discharge) is safest for introducing liquid refrigerant without risking liquid carryover into the operating compressor
