Vehicle Damage Warnings

SERVICE PRECAUTIONS
1. Never open or loosen a connection before recovering the system refrigerant.
2. When loosening a connection, if any residual pressure is evident allow it to be recovered before opening the fitting.
3. A system which has been opened to replace a component or one which has discharged through leakage must be evacuated before charging.
4. Immediately after disconnecting a component from the system, seal the open fittings with a cap or plug.
5. Before disconnecting a component from the system, clean the outside of the fittings thoroughly.
6. Do not remove the sealing caps from a replacement component until ready to install.
7. Refrigerant oil will absorb moisture from the atmosphere if left uncapped. Do not open an oil container until ready to use and install the cap immediately after using. Store the oil only in a clean moisture free container.
8. Before connecting an open fitting always install a new seal ring. Coat the fitting and seal with refrigerant oil before connecting.
9. When installing a refrigerant line avoid sharp bends. Position the line away from the exhaust or any sharp edges which may chafe the line.
10. Tighten fittings only to the specified torque. The aluminum fittings used in the refrigeration system will not tolerate over tightening.
11. When disconnecting a fitting use a wrench on both halves of the fitting to prevent twisting of the refrigerant lines or tubes.
12. Do not open a refrigerant system or uncap a replacement component unless it is as close as possible to room temperature. This will prevent condensation from forming inside of a component which is cooler than the surrounding air.
13. Keep service tools and the work area clean. Contamination of a refrigerant system through careless work habits is unnecessary.
