11. Glossary
y Recovery phase: The refrigerant is extracted from the
vehicle air conditioning system, cleaned and routed into the
internal bottle of the ACX1281. The refrigerant oil collected
in the process is drained into the used oil bottle at the
ACX1281.
y Vacuum phase: A vacuum is generated in the vehicle air
conditioning system. Measurement of the drop in pressure
begins as soon as the vacuum has been generated.
y
Charging phase: A certain quantity of refrigerant is added to
the vehicle air conditioning system.
