Shut-down
Should any solution remain in the hoses in freezing
weather, the entire system can be damaged. To avoid
this and any solution spillage, the system is equipped
with automatic drainage when the engine is switched
off so that hoses, the pump and injector are emptied
and the solution runs back to the tank.
NOTICE! The automatic drainage only works when the
engine is stopped using the ignition switch or the stop
button on the instrument panel (depending on
application), not if only the engine power supply is
disconnected. If the system is not drained properly,
solution may squirt out if the hoses are disconnected.
CAUTION!
The EATS system needs time to for automatically
drainage and depressurizing.
Wait at least two minutes after the engine been turned
off before removing the AdBlue/DEF hoses.

Overview

The system comprises:
1 Tank
2 Pump
3 Injector
4 EATS Catalyst and Muffler
5 Catalytic Converter
The atomized AdBlue®/DEF is sprayed into the
exhaust gases upstream of the catalytic converter.
