Cooling water strainer model 470
ENGLISH
3 Use and maintenance
• Inspect the strainer element regularly for
contaminents. N.B. The lid doesn’t need to be
removed for inspection.
• Clean the strainer element if dirt has accu-
mulated.
• Close the seacock.
• Twist and loosen the central button, rotate
the lid 90° and remove it.
• Remove the strainer element out of the hous-
ing and flush the strainer with clean water.
• Re-install the strainer element, grease the
O-ring and the thread with e.g. silicone oil or
teflon based spray and reinstall the lid.
Note: Always loosen or fasten the central but-
ton by hand. Never use tools to do so.
Caution:
Check the seal between lid and housing after
cleaning and re-assembling the strainer. An im-
properly sealed lid will result in air sucked in by
the sea water pump of the engine which again
will result in overheating of the engine.
To prevent damage of the water strainer, dur-
ing frost in the winter time, either the water
must be drained or the installation must be
filled with anti-freeze.
Remove the hoses to drain the strainer; the
housing is not equipped with a drain plug.
Take care that during filling with anti-freeze no
anti-freeze is spilled into the waterway. Anti-
freeze is poisonous.
