Routing to the Dosing Module (Injector)
It is important for the function of the dosing module to ensure that the dosing module is not routed downstream of DEF
lines or components. If this is unavoidable (for example on RH under exhaust systems) or Horizontal (Series) Exhaust a
routing trap must be installed . A minimum of 12” of line length must be routed below the dosing module, in order to catch
any leftover DEF when system is purged.
