Vehicle Damage Warnings

1. Never open or loosen a connection before discharging system.
2. When loosening a connection, allow any residual pressure to leak off before opening fitting.
3. A system which has been opened for replacement of a component, or which has discharged through leakage, must be evacuated before charging.
4. Immediately after disconnecting a component from system, seal open fittings with a cap or plug.
5. Before disconnecting a component from system, clean outside of fittings thoroughly.
6. Do not remove sealing caps from a replacement component until it is ready to be installed.
7. Refrigerant oil will absorb moisture from atmosphere if left uncapped. Do not open an oil container until ready to use, and install cap immediately after using. Store oil only in a clean, moisture-free container.
8. Before connecting an open fitting, always install a new sealing ring. Coat fitting and seal with refrigerant oil before making the connection.
9. When installing a refrigerant line, avoid sharp bends. Position line away from exhaust or any sharp edges which may chafe line.
10. Tighten fittings only to specified torque. Do not overtighten.
11. When disconnecting a fitting, use a wrench on both halves of fitting to prevent twisting of refrigerant lines or tubes.
12. Do not open a refrigerant system or uncap a replacement component unless it is close to room temperature. This will prevent condensation from forming inside a component which is cooler than surrounding air. Whenever a major component such as an evaporator, condenser, compressor, or refrigerant line is replaced, it is mandatory that the suction accumulator/drier also be replaced.
13. Keep service tools and work area clean. Contamination of a refrigerant system through careless work habits must be avoided.
