CAUTION: If the low-side (blue) or high-side (red) coupler valve is left open during the hose clearing process, the system will pull refrigerant back out of the vehicle.
Note: The charge process includes an automatic vacuum leak test, after which the system is pressurized with a small amount of refrigerant for a manual leak test.
• If the leak test passes, the refrigerant is automatically recovered and the selected charge is added.
• If the leak test fails, the refrigerant needs to be recovered and the vehicle needs to be checked for leaks by using an electronic leak detector.

The Robinair unit is designed to meet all applicable agency certifications, including Underwriter's Laboratories, Inc., SAE Standards, and CUL. Certain state and local jurisdictions dictate that using this equipment to sell refrigerant by weight may not be permitted. We recommend charging for any A/C service by the job performed. This weight scale provides a means of metering the amount of refrigerant needed for optimum A/C system performance as recommended by OEM manufacturers.
La unidad Robinair está diseñada para cumplir con todas las certificaciones de agencia aplicables, incluyendo Underwriter's Laboratories, Inc., Estándares SAE y CUL. Ciertas jurisdicciones estatales y locales prescriben que el uso de este equipo para vender refrigerante por peso es posible que no sea permitido. Recomendamos que se cobre el trabajo realizado por dar servicio al aire acondicionado. Esta escala de peso proporciona un medio para medir la cantidad de refrigerante que se necesita para el rendimiento óptimo del sistema de aire acondicionado, tal como lo recomiendan los fabricantes OEM.
La machine Robinair a été conçue pour répondre à toutes les certifications applicables, y compris celles de l’organisation Underwriters Laboratories, Inc., ainsi qu’aux normes SAE et CUL.
