2.6
Proper disposal
At the end of its service life, this equipment must
be disposed of as follows:
— Contact the service center to have the refrigerant
in the unit recovered and recycled.
— Consign the unit to an authorized collection
center according to local legislation.
2.7
Recycled material disposal
—
Return the refrigerant recovered from
the unit to the refrigerant supplier for
proper disposal or recycling.
— Lubricants extracted from the vehicle's
A/C system must be returned to an
official oil collection center
2.8
Packaging disposal
Electronic and electrical A/C service
equipment must never be disposed of with
domestic waste, but recycled
appropriately.

Glossary
Recovery phase: The refrigerant is extracted from the
vehicle air conditioning system, cleaned and routed into the
internal bottle of the AC442. The refrigerant oil collected in
the process is drained into the used oil bottle at the AC442.
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.
Charging phase: A certain quantity of refrigerant is added
to the vehicle air conditioning system.
