Maintenance: Freshwater system
Freshwater system. Flushing clean
The system should be flushed before changing cool-
ant to avoid inferior cooling performance due to de-
posits in the cooling system.
IMPORTANT! Certain parts of the system are
made of light alloy. Chemical additives must
therefore not be used when cleaning.
1. Drain the coolant as described earlier.
2. Insert a hose into the filler opening in the heat ex-
changer and flush with fresh water.
3. Flush until the water running out of the drainage
points is clean.
4. Close all drainage points when all the fresh water
has run out.
5. Fill with coolant.

Coolant filter. Change
A coolant filter is available as an accessory. It filters
the coolant and adds anti-corrosion agent.
IMPORTANT! Do not change the filter when the
coolant is changed. The concentration of rust-
preventer in the coolant can become too high,
which would cause foaming and impaired cool-
ing.
Change the filter for the first time six months af-
ter the first coolant change and then every 1000
hours/12 months.
WARNING! Hot coolant and hot surfaces can
cause burns.
Close the cocks (1). Dismantle the filter using a suit-
able filter wrench. Moisten the gasket on the new filter
and screw on by hand. Tighten a further 1/2 turn after
the gasket has made contact. Open the cocks (1).
