Refrigerant Circuit, Draining

Refrigerant is never to be allowed to escape into the atmosphere, but rather it is to be extracted from the refrigerant circuit using an extractor or A/C service station. The drained refrigerant will be locally recycled or is send to an environment-recycling place to the manufacturer (different or additional laws may apply in individual companies). Transfer the vehicle to a workshop that has the necessary tools and equipment and where the work can be performed by qualified personnel.

Reason:

If refrigerant R134a is released into the environment, it enhances the green house effect.

• Refrigerant R134a has far less of a greenhouse effect than R12.

• Because R-134a does not contain chlorine atoms, the major catalyst in ozone depletion, refrigerant R-134a has no ozone depletion potential. Depletion of the ozone layer in the upper atmosphere is however only brought about by the splitting of carbon-chlorine bonds (as is the case, for example, with refrigerant R12).

After discharging the air conditioner, disconnect harness connector from A/C Compressor Regulator Valve (N280) or from the High Pressure Sensor (G65).

Reason:

The A/C compressor regulator valve (N280) is no longer activated and the A/C compressor runs at idle. The A/C compressor is designed so the lubrication of the A/C compressor components at idle is guaranteed by an internal oil circuit (as long as there is enough refrigerant oil in the A/C compressor).
