CAUTIONWith the engines in operation the extractor must always switched ON.
It’s suggested to keep them ON for at least 30 minutes, after switched OFF the engine, to eliminate the residual heat.
During operation, due to their surface temperature, the engines propagate radiant heat, which must be eliminated through efficient ventilation.
Air inlet and discharge openings are positioned so as to have the air flow passing through the whole room.
The yacht’s diesel engines (propulsion engines and generator) suck combustion air directly from the engine room.
The external fresh air enters the engine room through two inlets (air intakes) located on the bulwark on both sides of the yacht.
The air extraction is of the forced type, by means of three air extractors (1) (sucking fans) which extract the hot air from the engine room.
When the engine ignition keys are set to ON, the air extractors are automatically started.
In order to start the air extractors, in manual mode and with the ignition keys set to OFF, press the start/stop push-buttons located in the helm position.
The power supply of the extractors is controlled by the SHUTDOWN system of the fire fighting system that, in case of automatic fire extinguishing system activation, or when operating the tie rod, shuts down the air extractors in order to prevent air change in the room.
CAUTIONWith the engines in operation the extractor must always switched ON.
It’s suggested to keep them ON for at least 30 minutes, after switched OFF the engine, to eliminate the residual heat.
DANGERCarbon monoxide poisoning
Fossil fuel combustion generates a high quantity of carbon monoxide.
This gas is a colourless, odourless and highly toxic. When the engines and/or the generator are running, the yacht must be properly ventilated, in particular if underway at low speed, or when the exhaust fumes may blow back on board (e.g. when the yacht is shored or anchored or riding the anchor).
CAUTIONDo not place any type of equipment or clothing on the air extractors or in the air intakes, as this may damage the rotating parts of the electric extractors or obstruct the passage of air.
CAUTIONDo not accidentally obstruct the external grates with any objects (such as towels, etc..).
