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.
