Refrigerant Identification
WARNING: This page is about a different car, the 2015 Lincoln MKT. However, it is still accessible from the selected car via links, so may be relevant.
- 1.NOTE: Refrigerant Identification Equipment must be used to identify gas samples taken directly from the refrigeration system or storage containers prior to recovering or charging the refrigerant system.NOTE: Use Refrigerant Identification Equipment that conforms to SAE J1771 for R-134a or SAE J2912 standard identifies R-134a and R-1234yf.
Follow the instructions included with the Refrigerant Identification Equipment to obtain the sample for testing.
- 198-RI2012yfp A/C Refrigerant Analyzer for use with R134a and R1234yf vehicles Use the General Equipment: Refrigerant Identification Equipment

The Refrigerant Identification Equipment displays one of the following:- If the purity level of R-134a is 98% or greater by weight, the green PASS LED lights. The weight concentrations of R-134a, R-12, R-22, hydrocarbons and air is displayed on the digital display.
- If refrigerant R-134a does not meet the 98% purity level, the red FAIL LED lights and an alarm sounds alerting the user of potential hazards. The weight concentrations of R-134a, R-12, R-22 and hydrocarbons are displayed on the digital display.
- If hydrocarbon concentrations are 2% or greater by weight, the red FAIL LED lights, "Hydrocarbon High" is displayed on the digital display, and an alarm sounds alerting the user of potential hazards. The weight concentrations of R-134a, R-12, R-22 and hydrocarbons are displayed on the digital display.

The percentage of air contained in the sample is displayed if the R-134a content is 98% or greater. The Refrigerant Identification Equipment eliminates the effect of air when determining the refrigerant sample content because air is not considered a contaminant, although air can affect A/C system performance. When the Refrigerant Identification Equipment has determined that a refrigerant source is pure (R-134a is 98% or greater by weight) and air concentration levels are 2% or greater by weight, prompts the user if an air purge is desired.
