Securing the fuel pre-filter

must not
be mounted directly on the engine as the engine
vibrations impair water separation.
There must be sufficient space available for catch
ing the separated water and for changing the filter
cartridges (H approx. 200 mm).
The changeover lever must be easily accessible
and freely movable.
Mounting bolts: M10 hexagon bolts or M10 socket
head bolts, each with DIN 125-10.5 washers.
Connecting the fuel pre-filter
To connect the fuel hoses of the tank - fuel pre-fil
ter and the fuel pre-filter - engine, screw fittings are
delivered with the equipment; these can be com
bined depending on the installation situation.
The fuel inlet is marked "IN" on the fuel pre-filter.
The fuel outlet can be either on the same side as
the fuel inlet or on the opposite side. The free out
let opening must be fitted with a screw plug in
each case.
