Refrigerant Lines With Inner Heat EXCHANGER, Removing And Installing: Notes

The removal and installation of the refrigerant line from the separating point on the right longitudinal member to the expansion valve is described in the following. This refrigerant line is installed on vehicles with a high voltage system as inner heat exchanger.

On vehicles with a high-voltage system a refrigerant line without an inner heat exchanger is installed with a Heater and A/C Unit Refrigerant Shut-Off Valve -N541-. The removal and installation of the different versions is the same in principle. On vehicles with a high-voltage system only the connector to the Heater and A/C Unit Refrigerant Shut-Off Valve -N541- must be additionally separated. Refer to HEATER AND A/C UNIT REFRIGERANT CUT-OFF VALVE -N541-, REMOVING AND INSTALLING .

Certain tools are required to discharge the refrigerant circuit. These work procedures must only be performed by trained personnel. Refer to REFRIGERANT CIRCUIT, DISCHARGING WITH A/C SERVICE STATION (R134a) / REFRIGERANT CIRCUIT, EVACUATING WITH A/C SERVICE STATION (R134a) / REFRIGERANT CIRCUIT, CHARGING WITH A/C SERVICE STATION (R134a) (Refrigerant R134a Servicing, Refrigerant Circuit, Working with A/C Service Station) and REFRIGERANT CIRCUIT, DISCHARGING (R1234yf) / REFRIGERANT CIRCUIT, EVACUATING (R1234yf) / REFRIGERANT CIRCUIT, CHARGING (R1234yf) .
