Danger! | Risk of burn injuries and scalding when working at AdBlue lines and the components attached to them. Risk of injury to skin and eyes when handling AdBlue. Risk of poisoning caused by swallowing AdBlue | Only pour AdBlue into suitable containers. Wait until pressure is released before starting any work on the exhaust aftertreatment system. | |
| Notes on use, material properties and handling of AdBlue | ||
1 | Remove protective cap on valve (6) | If a valve cap and protective cap in the previous design are still installed at the pressure reservoir (4), a valve cap in the new design must be installed. The new valve cap has an inside seal and is installed without protective cap. | |
| Pressure reservoir for pump module changed | ||
2 | Press valve (6) until pressure reservoir (4) empties fully. | ||
3 | Remove housing cover (7) together with the pressure reservoir (4) | ||
| Install | ||
4 | Clean housing cover (7), the pressure reservoir (4) and pressure reservoir housing (3) and check for damage | Replace housing cover (7) together with pressure reservoir (4) if necessary. | |
5 | Install housing cover (7) together with the pressure reservoir (4) | Clean contact surfaces for O ring (5) using clean rags and water. | |
Thinly coat O-ring (5) with lubricant before assembly. | |||
Absolutely ensure to use the prescribed lubricant and ensure that it is used extremely sparingly. Damage can occur on the EATS otherwise. | |||
