Refrigerant Recovery/Evacuation
DEFINITIONS
Recover
To remove refrigerant, in any condition, from a system and 
store it in an external container, without necessarily testing 
or processing it in any way.
Recycle
To clean refrigerant for re-use by oil separation and single 
or multiple passes through devices, such as replaceable 
core filter-driers, which reduce moisture, acidity and 
particulate matter. This term usually applies to procedures 
implemented at the field job site or at a local service shop.
Reclaim
To reprocess refrigerant to new product specifications (see 
below) by means which may include distillation. A chemical 
analysis of the refrigerant is required after processing to be 
sure that product specifications are met. This term usually 
implies the use of processes and procedures available only 
at a reprocessing or manufacturing facility.
Chemical analysis is the key requirement in this definition. 
Regardless of the purity levels reached by a reprocessing 
method, refrigerant is not considered “reclaimed” unless it 
has been chemically analyzed and meets ARI Standard 700 
(latest edition).
New Product Specifications
This means ARI Standard 700 (latest edition). Chemical 
analysis is required to assure that this standard is met.
