NOTE:
- Prior to recovering or charging the refrigerant system, you must use an A/C refrigerant analyzer to identify gas samples taken directly from the refrigeration system or storage containers.
- Follow the instructions included with the refrigerant analyzer to obtain the sample for testing.
- The analyzer will display one of the following:
- A green "PASS" light emitting diode (LED) will light if the purity of the R-134, R-12 or the R-22 is better than 98% by weight.
- A red "FAIL" LED will light if the purity of the gases does not meet the 98% purity standard.
- A red "FAIL" LED and "HYDROCARBON" light will illuminate and a horn will sound if a hydrocarbon is detected above 5%. This will alert the user of potential hazards.
- If contaminated refrigerant is detected, DO NOT recover the refrigerant into your recovery/recycling equipment. For additional information, refer to the CONTAMINATED REFRIGERANT HANDLING in this section.
