R Re ec co ov ve erry y::
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.
R Re ec cy yc clliin ng g::
To clean refrigerant for reuse 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.
R Re ec clla aiim m::
To reprocess refrigerant to new product
specifications by means which may include
distillation, will require chemical analysis of the
refrigerant to determine that appropriate product
specifications are met. This term usually implies
the use of processes or procedures available only
at a reprocessing or manufacturing facility.

Whenever testing a compressor, extreme caution
should be used to prevent damaging the terminals.
A compressor with a damaged terminal or a
grounded winding can expel a terminal from its
insulated housing when the compressor is
energized. If this happens, a mixture of refrigerant
and oil will be released that could be ignited by an
external heat source (open flame, heater, etc.).
Also, if there is air in the system when this
happens, a spark at the compressor shell could
ignite the refrigerant and oil mixture.

Overcharging a refrigeration system with refrigerant
can be dangerous. If the overcharge is sufficient
to immerse the major parts of the motor and
compressor in liquid refrigerant, a situation has
been created which, when followed by a sequence
of circumstances can lead to the compressor shell
seam separating.
A hydraulic block occurs, preventing the
compressor from starting. This condition is known
as locked rotor. Electric current continues to flow
through the compressor motor windings which
become, in effect, electric resistance heaters.
The heat produced begins to vaporize the excess
refrigerant liquid causing a rapid increase in
system pressure. If the compressor protective
devices fail, the pressure within the system may
rise to extremes far in excess of the design limits.
Under these conditions, the weld seam around the
compressor shell can separate with explosive
force, spewing oil and refrigerant vapor which
could ignite.
To eliminate this exceedingly rare but potential
hazard, never add refrigerant to a sealed system.
If refrigerant is required, evacuate the existing
charge and recharge with the correct measured
amount of the refrigerant specified for the system.
