Guidelines For Clean Working Conditions

Even a small amount of contamination can lead to malfunctions. Therefore, observe the following guidelines 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 removed components on a clean surface and cover them with lint-free cloths.
• Carefully cover opened components or seal if the repair cannot be performed immediately.
• Only install clean parts: Unpack replacement parts just before installing them. Do not use any parts that have been kept out of packaging (for example, in a toolbox).
• Do not work with compressed air when the system is open.
• Protect the disconnected connectors from dirt and moisture and only connect them when they are dry.
