Vehicle Damage Warnings

SERVICE PRECAUTIONS
Never open or loosen a connection before discharging the system with a recycling machine such as the R-134a A/C Service Center 176-00001 or the R-134a Mobile Recycling Center 023-00150 or equivalent.

When loosening a connection, allow any residual pressure to leak off before opening the fitting.

A system which has been opened for replacement of a component, or has been discharged through leakage, must be evacuated before charging.

Immediately after disconnecting a component from the system, seal open fittings with a cap or plug.

Before disconnecting a component from the system, clean the outside of the fittings thoroughly.

Do not remove sealing caps from a replacement component until it is ready to be installed.

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.

Before connecting an open fitting, always install a new O-ring seal. Coat the fitting and O-ring seal with refrigerant oil before making the connection.

When installing a refrigerant line, avoid sharp bends. Position the line away from the exhaust or any sharp edges which may chafe the line.

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 the surrounding air.

Whenever a major component such as an A/C evaporator core, A/C condenser core, A/C compressor, or refrigerant line is replaced, it is mandatory that the suction accumulator/drier also be replaced.

Keep the service tools and work area clean. Contamination of a refrigerant system through careless work habits must be avoided.

Whenever components in the engine compartment or instrument panel areas are being serviced, the battery ground cable must be disconnected to eliminate the 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.
