RECOVER REFRIGERANT FROM REFRIGERATION SYSTEM
Start up the engine.
Turn the A/C switch on.
Operate the cooler compressor at an engine speed of approximately 1000 rpm for 5 to 6 minutes to circulate the refrigerant. This causes most of the compressor oil from the various components of the A/C system to collect in the A/C compressor.
Stop the engine.
Recover the refrigerant from the A/C system using a refrigerant recovery unit.
