Final answer:

The initial steps after installing a refrigeration or air conditioning system are pulling a vacuum, pressurizing with nitrogen, and then charging with refrigerant.


Explanation:

After installing a refrigeration or air conditioning system, the correct sequence of steps to be performed first is:

  1. Pull a vacuum on the system: This is done to remove any air and moisture from the system before charging it with refrigerant.
  2. Pressurize the system with nitrogen (inert gas) and leak test: This helps ensure that there are no leaks in the system that could affect its performance.
  3. Charge the system with refrigerant: Once the system has been evacuated and checked for leaks, refrigerant can be added to make it operational.
