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.
