As is shown in the figure, fuel coming from a tank
K fitting is taken in by suction by the pump G via
a hose H and then fed to the joint C via the hose
F.
The amount of fuel necessary for generating set
operation will be fed through the hose J to the
generator unit A; while any excess fuel will return
to the tank via the return fitting E.
Inside the joint C, a flow rate reducer B should be
installed consisting in a fit-in cylinder with a 2.5
mm ID. Each pipe coupling must be secured with
a special clamp.
On the generating set front is a three-pole con-
nector (Fig.13 Ref.8). Checking the wiring dia-
gram, identify the two auxiliary fuel pump control
poles (+12 and GND ). Two cables with minimum
cross sections of 1 mm² must be connected to
those two Faston terminals with special connec-
tors to reach the auxiliary pump poles. (Fig.15
Ref. G)
4.9 (Optional) tank installation instructions
The fuel tank installation position (Fig. 10) must
be chosen so as to ensure that the fuel hose
length is reduced to a minimum.
Also ensure that the hose cross-section is not re-
duced due to choking, bending or crushing. We
advise the install the tank at the same height as
the generating set; in any case, the installation
height difference should never exceed 20 cm
(Fig. 16).
Should it not be possible to observe the maxi-
mum permitted level difference requirements, an
electric fuel pump can be installed (available as
an optional part, code 00507) which can easily
overcome over 1 metre level differences between
the fuel tank and the generating set.
See paragraph 4.8
Do not install the fuel
tank next to sources of heat; the tank should
be protected from the risk of outside water
seeping.
Carry out the fuel tank-to-generating set connec-
tion by using a rubber hose (Fig.16 Ref. 2) suit-
able for unleaded fuel with an ID of 5 mm inter-
posing a fuel filter (Fig.16 Ref. 1).
The tank requires an outlet and a special hose is
connected to the special hose connector to this
end (Fig.16 Ref.3). Make sure that the outlet
hose path is upwards (Fig.16 Ref.4) and straight-
lined without any elbows.
Dealers can supply two different fuel tank models
to meet any installation requirements.
•
For standard vehicle installation, use the op-
tional tank code 05472 (Fig.16 Ref.8) with a
capacity of 15 litres; the filler (Fig.16 Ref.5) is
supplied complete with a closing plug. (Fig.16
Ref. 6)
•
The optional tank code 05466 (Fig. 18) with a
capacity of 15 litres has been designed for in-
stallation at different positions to make the
most of the available vehicle space and to en-
able filler (Fig. 17) connection at two different
locations (Fig.18 Ref. 1 and 2). This enables
the installer to choose the most suitable solu-
tion each time ac-cording to the type of instal-
lation.
The fuel cut-off tap (Fig. 18 Ref. 3) can also be
screwed onto two different threaded pipe fittings
(Fig.18 Ref. 4) according to different installation
positions.
