- 1.NOTE: Use Refrigerant Identification Equipment 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 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
- 2.NOTE: The refrigerant identifier displays one of the following:
- If the purity level of R-134a is 98% or greater by weight, the green PASS LED. The weight concentrations of R-134a, R-12, R-22, hydrocarbons and air will be displayed on the digital display.
- If refrigerant R-134a does not meet the 98% purity level, the red FAIL LED 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, "Hydrocarbon High" will be 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 also are displayed on the digital display.
- 3.
The percentage of air contained in the sample is displayed if the R-134a content is 98% or greater. The refrigerant identifier 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 identifier 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, it prompts the user if an air purge is desired.

If contaminated refrigerant is detected, repeat the refrigerant identification test to verify the refrigerant is indeed contaminated.
- 5.NOTE: If contaminated refrigerant is detected, DO NOT recover the refrigerant into R-134a recovery/recycling equipment. Recovery of contaminated refrigerant contaminates the recovered refrigerant supply and may damage the recovery/recycling equipment.NOTE: Install a new suction accumulator, receiver drier or receiver drier element as directed by the A/C system flushing procedure.
Recover the contaminated refrigerant using suitable recovery-only equipment designed for capturing and storing contaminated refrigerant only.
