SPECIAL INSTRUCTIONS FOR -SCR- EXHAUST SYSTEMS 6-15 E UROCARGO Euro 4/5 6.5.2.1 Instructions for lengthening and shortening the AdBlue ducts on the vehicle 1) Mark the delivery and returns ducts before separating them to ensure that they are correctly positioned during subsequent assembly. The maximum permitted length for ducts must not exceed 5 m from the reservoir to the supply module and 3 m from the supply module to the dosing module. 2) Cut the AdBlue duct (MLT Rehau - VOSS HWL 8.8 x 1.4 PA wall thickness 0.2 mm and 0.4 mm PA/PUR) with the appropriate pipe cutting clippers in order to ensure an accurate cutting area.
For reasons of space, it is advisable to divide the AdBlue delivery and return ducts along the length of the line.
