General warnings
It is essential to repeat the type approval if any change is made to the system layout.
NOTE
Observe the following warnings when carrying out operations that involve fuel system components.
•
Before any operation, close the taps on the solenoids of each gas cylinder, then start the engine and leave running until all
the gas in the lines has been used up and the engine stalls. For versions with an additional fuel tank, the engine must be left
running until the vehicle switches to recovery mode, i.e. begins to run on petrol.
•
Make sure the parts are cleaned, ensuring that no sludge or foreign bodies enter during handling and installation. For this
purpose, the protective covers on parts and sensors must not be removed until immediately prior to positioning.
•
Observe the direction of installation for all electrical connections.
•
All threaded connections must be tightened to the specified torque (see point B.3.3)
Fuel system components cannot be serviced and must be replaced if they are not efficient.
Washers, tapered washers, self-locking nuts and seals deform to improve tightening and they are also
of a special type. They must therefore be replaced whenever refitted.
New minor components must be systematically restored to their original positions in accordance with
the original installation sequence.
After valve replacement or any repair to the high pressure system, a HYDRAULIC LEAK TEST
(300 bar) must be carried out by an IVECO DEALERSHIP able to issue a test certificate if the outcome
is positive.
