System Familiarity

Before attempting any service that requires opening of refrigerant lines or components, the person doing the work should be thoroughly familiar with the information under "Handling Refrigerant-134a," "Handling Refrigerant Lines and Fittings," and "Maintaining Chemical Stability". Very carefully follow the instructions in the "Recovering the Refrigerant and Recycling, Adding Oil, Evacuating and Recharging Procedures".
