Engine oil

The engine is tested and charged with lubricating oil before delivery, except in the case of specific requirements relating to
delivery. The engine just needs fuelling up before it is started. If the oil needs topping up, refer to the engine instructions.
Excessive quantities of lubricating oil can cause permanent damage to the engine, do not exceed the
ATTENTION
level specified by the manufacturer.
3.14 Heating
Each fire-fighting diesel pump must be installed in a suitably heated room as room temperature must
ATTENTION
never fall below 10°C (see EN12845 10.3.3).
To improve engine reliability during start-ups in the cold season, the diesel engines are normally fitted (standard) with electric
heaters with thermostat control in order to keep the engine water (water-cooled engines) or engine oil (oil-cooled engines) within
the values recommended by the manufacturer for quick starting and drive without trouble for the engine.

Fuel system

All the diesel pumps come as standard with a floor-mounted fuel tank of a capacity suited to engine consumption and autonomy
required by standard EN12845. Provide on request (as accessory) additional tank the exact same size as the fuel tank for
collecting spilled fuel (obligatory as per standard UNI11292).
The installer must install the fuel tank making sure that:
- It is put in a position where it cannot transmit vibrations.
- It is installed in the vicinity of the diesel engine (fuel pipes less than 5 metres in length).
- It is NOT installed behind the radiator but to the side of the engine, leaving a minimum clearance of 600 mm (fig. 1).
- It is installed in a position ensuring ease of access for the personnel to top up the fuel.
- The fuel delivery on-off valve is higher than the fuel pump of the diesel engine.
- The air valve communicates with the outside.
The connecting pipes between the tank and engine provided are made to standard and are, therefore, suitable for use with fuel.
These points must be observed when setting up the fuel system:
ATTENTION
- Anchor the pipes at suitable intervals to prevent resonances, vibrations and deflections resulting from
the weight of the pipe itself.
- Use as few connectors as possible and ensure that fuel cannot leak out and air cannot enter the circuit.
- The supply pipes operate under a vacuum and are therefore subject to harmful air infiltration that could
prevent the engine from starting.
- Bends should be as gentle as possible avoiding bottlenecks and the "siphon" effect.
- The difference in height between the fuel delivery connection of the tank and the engine supply inlet
must be of no more than one metre, to ensure that the engine starts up and runs properly.
- The difference in height between the fuel return connection of the tank and the engine supply (fuel
return) outlet must be of no more than one metre and a half, to ensure that the engine starts up and
runs properly.
- Clean the pipes thoroughly.
- Use fuel suited to the type of engine!
- Provide a suitable reserve of fuel!
For safety reasons, the diesel pump sets are supplied without any fuel, moreover the sets consume fuel during testing, therefore
an adequate reserve of fuel must be provided!
3.16 Starting batteries
The diesel pump comes as standard with a set of starting batteries. For safety reasons, and to prevent any accidental start-ups,
the batteries are supplied disconnected.
Connect the batteries only after completing installation and with the electric panel with "Automatic mode disabled".
Observe these requirements when connecting the batteries:
- Check the condition of the batteries.
- Check the poles for traces of dirt and clean them if necessary.
- Check the charging level.
- Connect the terminals with care, always starting with the Positive pole and then the Negative pole.
