If all circuit are tied to the same suction line why is it necessary to pull all circuits

[@ryanbrown5334]

During installation you have to vacuum each circuit individually because they are valved off to the ODU. You can pull a vacuum on all circuits if the refrigerant has been recovered from the entire system. If you have a problem on one of the circuits it can be valved off and the other circuit(s) can remain in use. It is easier to diagnose a leak or line set issue on each individual circuit rather than trying to figure out which circuit might be the issue.
