WARNING

There is a danger of ice-up.

Refrigerant will leak out if refrigerant circuit is not discharged.

Refrigerant must be extracted before removing valve -C-. If refrigerant circuit is not opened within 10 minutes of extraction, pressure may form in refrigerant circuit due to evaporation. Extract the refrigerant once more.

Different threads for switch on high pressure and low pressure sides.

Only valves and o-rings that are resistant to refrigerant R134a and refrigerant oil must be installed.
