Before you start
- If air is sucked into the system through a badly closing filter cover there is a severe risk of overheating of the engine.
Procedure
- Close the raw water seacock.
- Remove the cover from the filter housing for inspection.
- Clean the filter element at least twice a year, or whenever necessary.
- When closing the strainer again, make sure the cover perfectly shuts the unit off without air leaks.
