WARNINGThere is a danger of ice-up. Refrigerant leaks out if refrigerant circuit is not discharged. Refrigerant must be extracted before opening the refrigerant circuit. If refrigerant circuit is not opened within 10 minutes of extraction, pressure may form in refrigerant circuit due to evaporation. Extract refrigerant once more.

Extract refrigerant using, for example -ROB 134APF-, only then open the refrigerant circuit. See notes, refer to REFRIGERANT CIRCUIT COMPONENTS OVERVIEW .
