Installing fuel pre−filter
The fuel prefilter with water separator À must not
be installed on the engine, because the vibrations
of the engine impair the function of the water
separator.
Caution:
The permitted vacuum pressure of
max. 0.35 bar upstream of the fuel pre−-
filter must not be exceeded even when the
filters are contaminated.
When installing the fuel pre−filter in the engine
room, care should be taken that there is adequate
space to trap the separated out water and to
change the filter cartridge.
Mounting bolts: Hexagon head bolts M10
or pan head bolts M10, respectively with washers
DIN 125−10.5.
Additional fuel pre−filter
You may install a Racor filter Á upstream of the
fuel filter delivered by MAN À.
Note:
The figures show a single filter. The
installation for the reversible double filter is
carried out in effectively the same manner.
