Description Function
Pressure Switches the compressor off in the normal operating
switch pressure is exceeded
Safety valve The safety valve opens if the design pressure is
exceeded
Circuit Interrupts the power supply if overcurrent is applied to
Breaker the AC442
Vents The AC442 is provided with vents in the housing to
ensure the exchange of air even when switched off.
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.
—
The packaging must be disposed of in
conformity with local legislation.
—
This contributes to protecting the

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.
