Very quick example of performing a refrigerant recovery on a car using the Fieldpiece MR 45 recovery unit.

As of last year in 2018 or it was the beginning of 2019 the EPA now requires you to pull recovered refrigerant down to -15 vacuum and hold for 15 minutes. If you find a vacuum raising example falling to 10 inches of vacuum turn back on the refrigerant recovery machine to below 15 inches of vacuum and hold again if the vacuum can hold 15 inches or greater you have completed your refrigerant recovery procedure. Remember when disassembling refrigerant lines do not open them up to atmosphere while they were under a vacuum they will dry and moist atmospheric air contaminating the refrigerant oil with moisture. Always break the vacuum with dry nitrogen to positive two or three psi to prevent the introduction of moist atmospheric air immediately plug all openings with airtight sealed gaskets or plugs.
