When a unit is inoperable or the compressor will not function, the refrigerant must be removed as a vapor. It can be removed from almost any convenient service port on the compressor or receiver tank. Because refrigerant must evaporate in the unit before removal, it is less efficient and more time consuming than the liquid removal process.
1. Attach a service line between one of the units service ports and the recovery machine inlet.
2. See the recovery machine for refrigerant vapor removal and recover the refrigerant.
