When preparing to use a recovery unit, which of the following should be checked?

Temperature of the refrigerant
Type of refrigerant present
Service valve positions
Type of compressor used

The correct answer is: Service valve positions

When preparing to use a recovery unit, it is essential to check the service valve positions. Ensuring that the service valves are positioned correctly is crucial for effective and safe recovery of refrigerants. Proper positioning allows for the isolation of the system from the recovery unit, ensures that the refrigerant is directed correctly into the recovery tank, and prevents any unwanted refrigerant leaks into the environment. The other factors, while important, do not directly impact the initial preparation of the recovery unit as much as service valve positioning. For example, knowing the temperature of the refrigerant can be helpful in understanding its state and behavior during recovery, but it does not affect the operational process of the recovery unit itself. Similarly, identifying the type of refrigerant helps ensure compatibility with recovery equipment and proper handling procedures, but again, this is secondary to having correct service valve settings. The type of compressor, while relevant in assessing the overall system characteristics, is not necessary to check when initially preparing the recovery unit for use.
