Freshwater system, Flushing
The cooling system should be flushed when the
coolant is changed, to avoid loss of cooling
performance due to deposits in the cooling system.
1 Drain the coolant, please refer to Coolant,
Draining, page 51.
2 Put a hose into the filling hole in the heat exchanger
and flush with fresh water.
3 Flush until the water which runs out of the drain
points is clean.
4 Close all drain points when all coolant has run out.
5 Fill up with coolant, please refer to
Maintenance, page 50.
