Recovery & RecyclingQuestion 219 of 240
Recovering liquid refrigerant before vapor on a large system is recommended because it:
a.Removes the bulk of the charge much faster
b.Is required before recycling
c.Cleans the refrigerant
d.Prevents the cylinder from overfilling
Explanation
Pulling liquid first moves the largest portion of the charge quickly, then vapor recovery finishes drawing the system down to the required level. This shortens the job significantly on a big system. It is a technique choice, not a cleaning or a legal recycling prerequisite.
