Section 50 - Climate Control - Chapter 2
Overview
In many c oun tr ies, r ecov er y, recycling an d
reclamation have legal definitions and standard
meanings in the mobile A/C industry.
Recovery is transferring refrigerant in any condition
from a system to a storage container without testing
or purifying the refrigerant in any way.
Recycling is the cleaning of refrigerant for reuse by
oil-separation, non-condensable gas removal and
single or multiple passes through filter/moisture
absorption devices.
Reclamation is processing refrigerant to a level
equal to new product specifications as determined by
chemical analysis, (testing to ARI 700).
In servicing A/C systems with OEM1415, when
"recover" is depressed, the refrigerant in the vehicle
is transferred to the recovery tank on the unit without
testing or purifying. At the same time, SP-20 PAG oil
is separated from the r efr i gerant and s tore d
separately in the reservoir. This oil requires proper
disposal and should never be returned to the vehicle.
When "vacuum" is depressed, the vacuum pump on
OEM1415 evacuates the atmosphere in the vehicle
A/C system to a vacuum of 28 to 29-1/2 inches of
mercury (Hg). Air and moisture are removed in the
process, and only SP-20 PAG oil remains in the
vehicle's A/C system.

OEM1415
When "recycle" is depressed, the entire contents of
the recovery tank on OEM1415 are "recycled." The
refrigerant in the tank is passed through a filter-drier
in OEM1415 and cleaned; non-condensables are
removed, and air is purged automatically. (Older
recovery units like OEM1418 have manual air purge.)
NOTE: In automatic operation, recycling begins
about 5 seconds after the vacuum pump starts.
NOTE: During recycling, some additional SP-20
PAG oil is separated from the refrigerant and stored
separately in the reservoir.
Only new SP-20 PAG oil is added to replace the oil
which was separated during recovery, and when
"recharge" is depressed, only clean "recycled"
refrigerant is returned to the vehicle's A/C system.
