Fuel Treatment System - Initial Start-Up - MTU 16V4000M*3 series Operating Instructions Manual

5.11 Fuel treatment system – Initial start-up
Overview of fuel treatment system
1 Pressure-free overflow
2 Bypass 1
3 Bypass 2
4 Safety valve, 3 bar
5 Ball valve, inlet
6 Pressure gage
7 Ventilation, sample extrac-
tion
8 Differential pressure gage
Switching on fuel treatment system
1. Switch on fuel treatment system (→ Page 106).
2. Check differential pressure at differential pressure gage (8). Differential pressure in a new system: 0.1 bar to
0.3 bar.
Result: If no differential pressure is measured, the coalescer filter element is probably being bypassed.
1. Remove coalescer filter element (→ Page 247).
2. Check sealing surfaces on coalescer filter element and in the pressure tank.
