SPECIAL INSTRUCTIONS FOR -SCR- EXHAUST SYSTEMS 6-9 E UROCARGO Euro 4/5 Specifications for installation and removal 6.5 Specifications for installation and removal The instructions that follow are intended for the AdBlue injection system of the Bosch DENOX2 type, within the SCR system. If Bodybuilders make changes to the frame, the following procedures must be followed under all circumstances: - disassembly: disconnect the hydraulic connectors first and then the electric connectors; - assembly: connect the electric connectors first and then the hydraulic connectors.
Compliance with this assembly/disassembly procedure will ensure that AdBlue does not come into contact with the electric connectors. 6.5.1 Operations for positioning the AdBlue tank As regards the AdBlue tank, ensure that:
- the tank ventilation pipe is never closed; - the reservoir must contain at least 5 l of AdBlue at the end of each operation to ensure the dosing module is cooled; - after each operation, the tank does not contain more than 85% of AdBlue (corresponding to the max reading of the level sensor) with respect to the tank total volume, so as to guarantee enough room for AdBlue to expand during freezing at temperatures below -11 ° C; - when fitting equipment onto the chassis, there is enough room for the AdBlue fill gun (1, Figure 6.11) to fit completely and correctly into the tank filler.
If specific-shaped tanks are available, these must be made out of polyethylene or stainless steel 1.4301, 1.43, in each case the tank height must be respected. Specifications for installation and removal Print 603.93.431 Base - January 2008
