• A self-contained recovery unit has its own compressor (or other transfer mechanism) to
• pump refrigerant out of the refrigeration system

HCFC-123 along with CFC-11 and CFC-113 are all low pressure refrigerants.

CFC-12,CFC-114,CFC-500,502 anf HCFC-22 are all high pressure refrigerants

Only section 608 certified technicians may buy CFC-12 in containers smaller than 20 pounds

System-dependent recovery equipment relies solely upon the compressor in the small appliance and/or the pressure of the refrigerant in the appliance to recover the refrigerant

• Self-contained recovery equipoment(active)
• and System-dependent recovery equipment(passive)

After November 15,1993 all recovery and recyling machines must be certified to meet EPA requirements

All appliances must be equipped,but for small appliances this port typically is a straight piece of tubing that is entered using a piercing access valve (process tube)
