INTRODUCTION
Recycling equipment meeting SAE standards J1990 and J2210 is designed to extract and recycle refrigerants that
have been in mobile air conditioning systems only.
R134
A
refrigerant that also is used in non-mobile systems may
introduce contaminants to the refrigerant that equipment meeting SAE J1990 and J2210 cannot remove. This equip-
ment is not intended for use on non-mobile systems.
Using Extraction Equipment
Extraction equipment is relatively small and easily portable. It is best used if a shop must service vehicles, such as
agricultural or off-highway equipment, that cannot easily be brought into the shop. It is also convenient for shops that
must deal with a variety of different refrigerant types and exchange recovered refrigerant at some central location.
Always use extraction equipment on those refrigerants for which it was designed. The lubricants, hoses, and seals in
this equipment have been designed to work with only one refrigerant.
To help avoid a mix-up of service equipment and refrigerants, equipment hoses designed for use which each refrig-
erant are easily identifiable. New service hoses used with
R134
A
must have a black stripe along the hose length and
carry the designation "SAE J2196/ R134
A
" (hoses labeled "SAE J 2196" and lacking the black stripe were used for
R12.)
If you use extraction equipment and send your recovered refrigerant to a reclamation facility, reclaimed refrigerant you
purchase must meet the Air Conditioning and Refrigeration Institute standards of purity (ARI Standard 700-88). This
will ensure that the refrigerant you are using not only meets the purity requirements of SAE J1991 (for R12) OR J2099
(for
R134
A
), but also that it does not contain incompatible lubricants or other contaminants from non-automotive air
conditioning systems.
Using Recycling Equipment
Recycling equipment extracts and removes common contaminants from refrigerants. Recycling equipment designed
and certified to meet SAE standards can make refrigerant recovery from mobile air conditioning systems suitable for
reuse in automotive air conditioning systems. Like extraction equipment, SAE standards require that each piece of
recycling equipment be dedicated to a single refrigerant.
NOTICE: Only equipment capable of recovering and cleaning R134
A
to meet SAE J2099 purity levels carries a label
with the phrase "Design certified by Underwriters" Laboratories, Inc. for compliance with SAE J2099.
The Underwriters' Laboratories label must be specific that the equipment is "design certified" for the SAE J2099 stan-
dard. If not, it certifies only that the machine is free of reasonable shock or other electrical hazards to the user.
Recycling vs. Reclaiming
Recycled refrigerant has been recovered from a mobile air conditioning system and is cleaned by the same shop
that recovered it to meet J2099 for
R134
A
. The equipment designed to recycle refrigerant in the shop environment
removes only contaminants picked up during the operation of a mobile air conditioning system.
Refrigerant that is either properly recycled or reclaimed is adequate for use in mobile air conditioning systems.
