General
Vetus fuel filters/water
75100VTME, 79100VTME, 83100VTME,
87100VTME and 91100VTME have a
unique and patented filter with three filtra-
tion steps.
1) Firstly, 80% of the solid dirt particles and
the water, which is heavier than fuel, are
collected in the transparent collection
basin.
2) After this, the fuel flows upwards. Water
and solid dirt particles are separated
by means of the coalescence effect (to
coalesce is for microscopically small
fluid droplets to stick together as a larger
drop) and also collected in the transpar-
ent collection basin.
3) Finally, the fuel flows further upwards
through the filter mechanism, the prima-
ry function of which is to hold back the
smallest solid dirt particles and water:
this ensures a high degree of filtration
and a long lifetime for the fine filter on the
engine.
These filters are suitable for diesel fuel
only.

Installation
separators
Note:
Bear in mind the regulations that your
local authorities have imposed regarding
the specification and installation of fuel
tanks and pipework.
The filter is under pressure (with a
pressurised non-inflammable gas).
Prior to fitting the filter, remove the caps
on the connections to the fuel supply
line and open the valves to depressurise
the filter.
If the valves are opened (with a full fuel
tank) once the filter has already been
fitted, fuel will no longer be drawn into
the filter!
Layout
For vessels under construction:
(See illustrations A1 and A2)
Mount the suction pipe at the bottom of the
tank; the bottom of the tank is thus kept
clean at all times and the build-up of water
and bacteria is prevented.
The fuel return line must be led into the
top of the tank, and must feed down to the
bottom of the tank on the opposite side
from the suction pipe. This prevents foam
forming in the fuel tank: the constant flow
of fuel ensures that the build-up of dirt, and
thus cleaning expenses for the tanks, are
not incurred.
