General Information
CAUTION:^ Do not operate the detector in a combustible atmosphere since its sensor operates at high temperatures or personal injury and/or damage to the equipment may result.
^ Avoid breathing the A/C Refrigerant 134a (R-134a) and the lubricant vapor or the mist. Exposure may irritate the eyes, nose, and throat. Work in a well ventilated area. In order to remove R-134a from the A/C system, use service equipment that is certified to meet the requirements of SAE J 2210 (R-134a recycling equipment). If an accidental system discharge occurs, ventilate the work area before continuing service. Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.
Perform a refrigerant leak test on the system whenever you suspect a leak, or following any service operation that disturbs the components, the lines, or the connections. Many methods and special tools are available for this purpose. However, no matter which tool is used, care and diligence are the biggest keys to success.
