MAINTENANCE TASK. COOLANT CHECK
Allow the genset to cool. Release pressure from the cooling system before removing the
pressure cap. To release pressure, cover the pressure cap with a thick cloth and then slowly turn
the cap counterclockwise. Remove the cap after pressure has been completely released and the
genset has cooled. Check the coolant level at the tank, the level must be approximately 3/4 full.

MAINTENANCE TASK. COOLANT FILL / CHANGE
1. Drain off all the coolant by opening
the two drain plugs, one in the heat
exchanger and the other in the
cylinder block.
2. Close the drain plugs.
3. Remove bleeding bolt of thermostat
holder
4. Refill to the hole in the tank cap with

MAINTENANCE TASK. SEAWATER FILTER INSPECTION
It is important to install a seawater filter (supplied as accessory) between seawater cock
and the seawater pump to avoid that any impurity might clog the seawater circuit or seawater
pump.
To clean this filter:
1. Loose the cover top, turning it.
2. Remove the filtering component and clean it.
3. Fit it again taking care that the cover is well
seated on the o-ring.
4. Start the genset to check seawater leakages.
MAINTENANCE TASK. SEAWATER PUMP IMPELLER INSPECTION
Seawater pump impeller is neoprene and cannot rotate dried. If operated without water,
the impeller can be broken. It is important therefore that a spare impeller is always available.
Impeller inspection and replacement procedure:
1. Close the seawater cock.
2. Remove the seawater pump cover plate.
3. Remove the impeller from the shaft.
4. Clean the housing.
5. Inspect the impeller for damaged,
cranked, broken, missing or flattened
vanes. The impeller vanes should be straight
and flexible.
If it is damaged replace with a new one.
6. Lubricate the impeller with soapy water
before installation.
