Q

Immediately before the actual process of adding oil to a compressor cranckase is started, the oil charging hose should be properly prepared. How is this done?

🔍 Key Concepts

• Oil charging procedures for refrigeration or air conditioning compressors • Why air and moisture must be kept out of a refrigeration system • Common practice for preparing hoses in refrigeration service work

💭 Think About

• Which of these options removes air and moisture from the hose before it is connected to the compressor crankcase? • Which choice would be standard practice in refrigeration servicing, rather than something unusual or risky for seals and oil? • Think about what gas or method you normally use to sweep or displace air in a closed refrigeration system before opening it to oil.

✅ Before You Answer

• Make sure the method you choose would not introduce moisture or contaminants into the system oil. • Check whether the method is commonly used in refrigeration work to displace air from hoses and lines. • Avoid any option that could chemically affect the oil or damage the hose (excessive heat, aggressive solvents).
