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. |
