Refrigerant Identification / Testing

SPECIAL SERVICE TOOL(S) REQUIRED

REFRIGERANT IDENTIFICATION/TESTING CONTAMINATED REFRIGERANT
1. The A/C Refrigerant Analyzer is designed to identify vapor gas samples taken directly from automotive air conditioning systems or refrigerant storage cylinders. Refrigerant vapor passes through the multiple sensor Non-Dispersive Infra-Red (NDIR) sensing unit. The microprocessor calculates refrigerant type and purity percentage which is displayed on the Analyzers Liquid Crystal Display (LCD).
2. The Analyzer identifies the purity percentage of R134a, R12, R22, Flammable Hydrocarbon and Air in the sample. If the purity percentage of the R134a or R12 is 98% or greater by weight, a green "PASS" Light Emitting Diode (LED) will light. If they do not meet 98% purity the red "FAIL" LED will light. Levels of R22 and flammable HYDROCARBON's above 2% will light the "FAIL" LED. If a flammable hydrocarbon is detected above 5%, both the "FAIL" and "HYDROCARBON" LED will light and a horn will sound, alerting the user of potential hazards.
3. The Analyzer disregards any air which may be contained within the sample when calculating and displaying refrigerant purity percentage. However, the percent of air contained in the sample will be displayed if the R134a or R12 is 98% or above. It is important to note that the Analyzer eliminates the effect of air when determining the concentration of gas because air is not considered a contaminate but can affect A/C system performance. Air can be removed during the refrigerant recycling process, using UL certified recovery/recycling equipment.

RECOVERY OF CONTAMINATED REFRIGERANT
1. If contaminated refrigerant is detected DO NOT recover the refrigerant into your R-134a OR R-12 recovery/recycling equipment. Take the following actions:
1. Repeat the test to verify contaminated refrigerant is present.
2. Advise the customer of the contaminated A/C system and any additional cost to repair the system. The customer may wish to return to the service facility performing the last A/C service.
3. Recover the contaminated refrigerant using suitable recovery only equipment designed for capturing and storing contaminated refrigerant. This equipment must only he used to recover contaminated refrigerant to prevent the spread to other vehicles. As an alternative, contact an A/C service facility in your area with the proper equipment to perform this service. Refrigerant Recovery
