Refrigerant Circuit, Discharging with Service Station

Refrigerant Circuit, Discharging with Service Station

The refrigerant must be drained using an air conditioning service station and should not be released into the environment. 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). For this reason, the vehicle must be delivered to a workshop specializing in A/C systems (these workshops are equipped with the corresponding systems and tools).

Reason:

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

• Compared to R12, R134a has a substantially lower green house effect.

• Because R-134a does not contain chlorine atoms, the major catalyst in ozone depletion, (R134a) has no ozone depletion potential. The ozone depletion in the upper atmosphere is only initiated by splitting carbon-chlorine bonds (e.g. properties of R12)

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

Reason:

A/C Compressor Regulator Valve (N280) is then no longer activated and compressor runs at idle. This compressor is constructed in such way, that the components are lubricated at idle via an internal oil circuit (as long as enough oil is in compressor).
