17.3.3 Installation Configurations
C NOTICE! Protect the dosing and supply modules against stone chipping,
mud and debris under all operating conditions.
C NOTICE! Protect the supply module and hydraulic connectors from air flow
to help prevent freezing.
C NOTICE! Avoid heat transfer from the engine, gearbox, muffler, exhaust
pipes, and so on, into the DEF tank.
C NOTICE! Make sure the routing of the DEF hoses does not lead to additional
heat transfer into DEF, especially through engine cooled hoses for cooling
the dosing module.
C NOTICE! Make sure you use only DEF compatible materials in the DEF
circuitry.
Description of configurations
68 – 93 kW Top and Rear Mount Aftertreatment
108 & 129 Top Mount Aftertreatment Arrangement
Small Tank Module – Suitable for fuel tanks up to 479 litres
Large Tank Module – Suitable for fuel tanks up to 1500 litres
17.3.4 Tank Module Installations
The Tank module must be installed within the machine within a position so that the DEF
pressure line can be routed without straining and such that in a vertical distance the top of
the tank is less than 1.5 meters from the dosing module. Minimum inside bend radius of the
pressure line is 60mm. routing of the pressure line should be considered to avoid heat pick
up in the line.
In positioning the tank consideration should be given to the temperature around the tank – it
is not acceptable for the bulk DEF temperature to exceed a rise above ambient in excess of
10 degrees C
The protection against rocks, debris and splash water for each of the aftertreatment
components needs to be assessed by JCB / or trained distributers in the final application.
Diagram showing permissible relative position of the DEF Tank Module to the IPU is shown
in Figure 15. Figure 16 shows the details of the siphon requirements for the DEF pressure
line to the Dosing Module. The clipping points provided should be used to ensure this
requirement is met.
