7.3.6 Automatic filter (2F02)
When off-engine main filter, it is recommended to select an automatic filter with an insert filter
in the bypass line, thus enabling easy changeover to the insert filter during maintenance of
the automatic filter.
Automatic filters are commonly equipped with an integrated safety filter. However, some
automatic filter types, especially automatic filter designed for high flows, may not have the
safety filter built-in. In such case a separate safety filter (2F05) must be installed before the
engine.

80 kPa (0.8 bar)- alarm
7.3.7 Safety filter (2F05)
When off-engine main filter, a separate safety filter (2F05) must be installed before the engine,
unless it is integrated in the automatic filter. The safety filter (2F05) should be a duplex filter
with steelnet filter elements.
