Refrigerant Circuit Connections with Valve for Switches

  Note

Switch pressures, removing and installing switches as well as switch arrangement and version. Refer to vehicle specific refrigerant circuit → Heating, Ventilation and Air Conditioning; Rep. Gr.87; System Overview - Refrigerant Circuit (vehicle-specific repair manual).

  • Different threads for switch on high pressure and low pressure sides.
  • Only valves and O-ring seals that are resistant to refrigerant R134a and refrigerant oil must be installed.

A - Connection (soldered in)

B - O-ring seal

C - Valve (with O-ring seal)

  Note

To remove and install the valve insert -C- when the refrigerant circuit is discharged, use, for example, an adapter from the Refrigerant Sockets -T10364- (for the tightening specification. Refer to → Chapter "Connections with Schrader Valve (Needle Valve)").
