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. |
