RECOVERY REQUIREMENTS
Refrigerant Recovery and/or Recycling equipment manufactured after November 15, 1993, must be certified and
labeled by an EPA approved equipment testing organization to meet EPA standards.
The following is a list of the required recovery levels (in inches of mercury) for Type II appliances:
After reaching the desired vacuum, the technician should wait a few minutes to see if the system pressure rises,
indicating that there is still refrigerant in liquid form or in the oil. Appliances can be evacuated to atmospheric
pressure (O psig) if leaks make evacuation to the prescribed level unattainable. The technician must isolate a
parallel compressor system in order to recover refrigerant. Failure to isolate a parallel compressor system will
cause an open equalization connection that will prevent refrigerant recovery. System‐dependant recovery
equipment cannot be used on appliances containing more than 15 pounds of refrigerant.
Under EPA regulations, a “major repair” means any maintenance, service or repair involving the removal of any
or all of the following components: the compressor, the condenser, the evaporator or an auxiliary heat ex‐
changer coil.
