DRAINING THE COOLING SYSTEM

GB
In order to carry out maintenance on the water/air
Genset
exchanger or the cooling system, the seawater
intake circuit must be drained.

EPLACING THE ZINC ANODE
A sacrificial zinc anode (ref. 3) has been fitted in the
heat exchangers to protect them against galvanic
currents.
Periodically check the state of wear and replace it if
necessary, in order to prevent galvanic currents from
irreparably corroding the exchanger. It is recommended
to check the zinc anode at least once a month when the
generator is new in order to check how fast it wears,
and then act accordingly.
It is in any case advisable to replace the zinc anode at
least once a year.
