Volkswagen Golf Service & Repair Manual: Connections to valves for switches in the refrigerant circuit

  WARNING
Danger of freezing injuries.
If refrigerant circuit has not been evacuated, refrigerant will escape.
The refrigerant must be extracted before the valve -C- is removed. If the refrigerant circuit is not opened within 10 minutes after it has been evacuated, pressure may develop in coolant circuit due to re-evaporation. Extract refrigerant again.
The switches on the high-pressure and low-pressure sides have different threads.
   
Use only valves and O-rings that are resistant to refrigerant R134a and its associated refrigerant oils.
A -  Connection (soldered in)
