After reaching the required recovery vacuum, what should be done next with the appliance?

After reaching the required recovery vacuum, it is crucial to wait for a few minutes to check for pressure rise. This step is important because it allows the technician to verify that the vacuum is holding steady and that there are no leaks in the system. If the pressure rises significantly, it could indicate the presence of moisture or a leak, which could lead to further complications if repairs or recharging are attempted without addressing these issues first.

Waiting before proceeding is a standard practice in HVAC services, ensuring that the equipment is in the best condition for ongoing work and that any potential problems with the system can be identified early. By taking this precautionary step, you can save time and resources in the long run by ensuring that the system is properly prepared for repairs or recharging.
