🔍 Key Concepts

• Oil charging procedure for refrigeration compressors • Risk of introducing air or noncondensable gas into a refrigeration system • Effects of system pressure when adding oil with a hand pump

💭 Think About

• Which answer choice deals with what is going directly into the closed refrigeration system along with the oil? • What problems can air or noncondensable gases cause in a refrigeration system’s operation and pressures? • When using a hand pump, what step makes sure you are not adding anything except clean oil/refrigerant to the system?

✅ Before You Answer

• Identify which choice focuses on preventing contamination (air/noncondensables) rather than just pressure or isolation • Consider which step is typically done immediately before connecting to the crankcase for oil charging • Verify which option aligns with standard safe oil‑charging practice in marine refrigeration manuals
