Clean Working Conditions

Even slight contamination can lead to defects. Therefore observe the following rules for cleanliness when working on the A/C system: 

• Immediately seal the open lines and connections with clean plugs, for example from the Engine Bung Set:VAS6122  .
• Place the components that have been removed on a clean surface and cover, using lint-free shop rags.
• Carefully cover opened components or seal if the repair cannot be carried out immediately.
• Only unpack replacement parts immediately prior to installation. Do not use any parts that have been kept out of packaging (for example, in a tool box).
• Do not work with compressed air when working on an open system.
• Protect the separated connectors against dirt and moisture and only connect them when it is dry.
