LEEDING
THE
FUEL
SYSTEM
The fuel system is developed to eliminate, in
autonomous way, air bubbles penetrated inside the
system. For automatic bleeding activate the fuel
pump for few minutes before starting the engine.
To activate the fuel pump press for a moment the
"START" button (ref.1).
For the manual bleeding activate the fuel pump and loosen
the screw (
ref.2
).
If there are air bubbles in the fuel system, the engine will
not function regularly or will be unable to reach the rated
rpm. Air may penetrate the fuel circuit through a not
perfectly sealed joint (pipe, filters, tank) or when the fuel
in the tank is at minimum level.
6.11A
IR
FILTER
The
MARINER
series generators are fitted with a dry air
filter (
ref.3
), which prevents foreign bodies from entering
the combustion chamber. It is sufficient to clean the filter
mass with diesel fuel once a year to remove any
impurities.
Take the liquids used to wash the filter to special
waste collection centres for disposal.

THE
COOLING
SYSTEM
In order to carry out maintenance on the exchangers
and the cooling system, the seawater circuit must be
drained.
Carry out this operation as follows:
- close the seawater intake cock (
ref.4
);
- open the drain tap (
ref.5
) until all the water has
completely drained out;
- remove the cap (
ref.6
) and make the water draining
from water/water exchanger.
- close the drain tap.
Reopen the seawater intake cock before starting the
generator
.

EPLACING
THE
ZINC
ANODE
A sacrificial zinc anode (
ref.9-10
) has been fitted in the
heat exchangers (
ref.7-8
) 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.
