Operation
The engineroom ventilation system provides the necessary air exchange
for the correct operation of the propulsion systems of your BERTRAM
540 yacht.
The ventilation system consists of four ventilators, two of them are
located in the engineroom and the other two in the generator room; they
convey outside the air drawn inside, and by two lateral air inlets which
provide natural ventilation to the engineroom. The air inlets are equipped
with a air separating system from suspended water
To supplement the natural air ventilation, there is also a thermostatically
controlled forced air ventilation system.
The electric supply of the ventilators is performed by a switch located on
the main electric panel of the salon. When the blowers are in their normal
operating mode and the circuit breaker is turned on, the blowers
automatically operate when the engineroom temperature rises above 110
°F and turn off below 90 °F. The ventilators have a manual override
switch on the thermostat housing, which allows them to operate
regardless of engineroom temperature. This is valuable when working in
the engineroom.
NOTICES
Do not place tools or clothing on the extractors. Do not allow anything
to block the air inlets. Do not block the emergency closing device.
NOTICES
After navigation in particularly rough seas, it may be necessary to rinse
the salt residuals from the components near the inlets of the
engineroom.
NOTICES
With the engines on, it is recommended to have the ventilators under
thermostatic control. It is suggested to keep them on for at least 30
minutes after running the engines, to dissipate the engineroom heat.

DANGER
CARBON MONOXIDE DANGER NOTICE
Carbon monoxide (CO) is a potentially deadly, odorless, colorless
vapor present in the exhaust by-products of all fossil fuel burning
engine. While there is a substantially reduced CO presence in the
exhaust of diesel engines and a corresponding reduced hazard to
human beings, as compared to gasoline fueled engines, the hazard,
however limited, should be noted.
Keep cockpit, fly and stateroom areas well ventilated when engines
and/or generator are running and prevent the exhaust clogging. Do not
occupy swim platforms or aft lounging areas when engines and/or
generator are running.
Signs of exposure include nausea, dizziness and drowsiness,
symptoms similar to those of seasickness.
