Vetus WS180 Instructions D'installation page 4

1 General
The Vetus Water Separators/Fuel Filters WS180
and WS720 comprise the following compo‑
nents:
‑ A fuel filter which collects dirt particles.
‑ A water separator which separates water
from fuel, by making use of the fact that
water is more dense than the fuel.
The maximum water separation efficiency of
the Vetus WS180 and WS720 water separators/
fuel filters is over 90%. Combined with the fine
filter fitted to the engine, a water separation of
99% is achieved.
‑ Both types are suitable for either diesel or
petrol fuel.
‑ Two filter elements are connected in paral‑
lel in the WS720.
2 Installation
Take into account the regulations as laid
down by the local authorities concerning
the specification and installation of fuel
tanks and fuel pipes.
Arrangement
Fit the water separator/fuel filter in the fuel
supply pipe between the fuel tank and the fuel
supply pump. Position the water separator/
fuel filter as close as possible to the fuel tank in
relation to dirt deposits in the pipe.
Preferably install the water separator/fuel filter
higher than the top of the fuel tank. The advan‑
tage of this is if the filter should leak, the tank
will not run dry. See Drawing 1.

Install a valve at the tank suction connection.
Preferably install the whole fuel pipeline so
that it slopes down towards the tank.
All the fine filters installed before or after the
fuel pump must be retained.
Water Separator/Fuel Filter
Filters may never be fitted in such a way
that they 'hang' on the piping, but should
be mounted separately against a bulk‑
head or wall.
Mount the filter housing against a vertical
bulkhead.
Ensure that there is sufficient space under‑
neath to allow water to be drained from the
filter and to allow the filter element to be re‑
placed.
Take note of the direction of flow! This is indi‑
cated on the top of the water separator/fuel
filter.
WS180:
• Fit the two hose pillars provided (M14 x 1,5
‑ 8 mm).
WS720:
• Assemble the fittings in the filter housing.
Place the coupling nut and compression
ring over the pipe and screw the whole into
the fitting. Seal the unused inlet and outlet
connections with the sealing plugs sup‑
plied.
• Fill the filter element with clean fuel (4).
Lightly lubricate the sealing ring with en‑
gine oil (5).
• Screw up tight the new filter element in the
direction indicated. When the sealing ring
contacts the sealing surface (6), tighten the
