C3579 - Venting the fuel system
In normal state, the fuel system vents itself automatically. However, air may penetrate from leaking lines, or similar. If the alarm LED illuminates and the operating unit shows the message "Alarm Motorstart" (alarm engine start) in the display, then air may be in the fuel system.
Go through the following steps for venting the fuel system:
[1] Switch on the Transport refrigeration unit on the operating unit (ON/OFF button).
[2] Select diesel operation.
[3] Start the Transport refrigeration unit via the chamber button.
[4] The fuel system is being vented. If the diesel engine has not started after four start attempts, an alarm message appears.
[5] Switch the Transport refrigeration unit off at the operating unit (ON/OFF button) and repeat steps 1-4 until the diesel engine runs.
Carry this out a maximum of three times.
The fuel system is vented.
If the alarm message is displayed more than four times then contact the Cargobull Service.
