Connecting DFM 12ECO to a fleet manager or to a GPS

system

Before you start with the electrical connection of the system, you must have installed all the components delivered

correctly. This installation must be carried out by an authorised, certified company/person.

Please be aware: an incorrect installation could damage the DFM system and your vehicle. Aquametro shall accept no

liability in this instance.

Function description

• The supply line starts from the tank, goes to the pre-filter, to the fuel pump, to the supply line flow-meter, to the fine filter and then

to the injection pump.

• The injection pump injects the amount of fuel required and returns the rest via a return line, through the return line flow-meter to the

tank (see Schematic of a configuration). There is also what is known as "leak-line" from each injection valve which is connected to one

line via a T-piece to the return line before the return line flow-meter.

• The return line flows into the tank.

This is a general description. The actual situation can be different.

Installation description

The CONTOIL

12ECO has 2 flow chambers: supply line chamber and return line chamber. Those chambers are marked with an "S" for

supply and an "R" for return. The chamber fuel entry is marked by an arrow (see pictures).

Mount the CONTOIL

the fuel supply line. Connect the return line chamber in-between the fuel return line. Tighten all the connections.
