Vehicle Damage Warnings
SERVICE PRECAUTIONS1. Never open or loosen a connection before discharging the system.
2. When loosening a connection, if any residual pressure is evident, allow it to leak off 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 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 oil in a clean, moisture free container only.
8. Before connecting an open fitting, always install a new seal ring. Coat the filling and seal with refrigerant oil before connecting.
9. When installing a refrigerant line, avoid sharp bends. Position the line away from exhaust or any sharp edges which may damage the line.
10. Tighten the fittings only to specified torque. Do not overtighten.
11. When disconnecting a filling, 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 a component which is cooler than surrounding air.
13. Keep service tools and the work area clean. Contamination of a refrigerant system through careless work habits must be avoided.
14. Whenever components in engine compartment or instrument panel areas are being serviced, the battery ground cable must be disconnected to eliminate possibility of electrical shorts, burnt wiring, and dangerous fires. Extreme care must be exercised when performing electrical tests where the battery must be connected to operate the system.
