Cleaning seawater filter*
BM5-006M
Important
● Never open the filter housing
with the seawater valve open to
prevent water from entering.
● Observe the safety precautions
beginning on page 22
before performing any work on
the engine or in the engine
compartment.
If you deterimine soiling, proceed as
follows:
● Close the seawater valve.
● Unscrew the screws - see left illustration
- and remove the cover.
● Remove the filter element, flush it
thoroughly with clean water and refit it.
● Before screwing on the filter cover, the
sealing ring should be lubricated, e.g. with
silicone oil or Teflon spray.
● Check the cover and the gasket for
correct seating.
Important
If a cover is not seated correctly,
air can also be aspirated, causing
the engine to overheat.
● Open the seawater valve again.
● Start the engine and conduct a visual
inspection of the seawater filter* for leaks.
As the degree of soiling of the seawater
filter is depending on the water the engine
is operated in, you should check the filter for
soiling each time before starting the engine.
As the cover of the filter housing is transparent,
you do not need to open the cover.
