Mounting - Beta Marine Beta 14 Installation Manual

An engine will produce radiated heat - approximately
equal to / of the engine output power. Additionally,
1
3
larger amp starter battery and/or domestic battery
bank charging alternators create heat, building ambient
temperatures further.
As a consequence, it is highly important and the vessels
owner and/or installation engineer/s are responsible
to ensure that the engine compartment has adequate
ventilation to enable efficient internal combustion,
effective transference of heat out of the engine
compartment/room and prevent the accumulation of
gases, which might be emitted from starter batteries.

ENGINE MOUNTING
5 Anti-Vibration Mount (AVM)
To ensure vibration free operation, the engine must be
installed and correctly aligned on substantial engine
bearers, extending as far forward and aft as possible, well
braced and securely fastened to form an integral part of
the hull.
The engine must be installed as low as possible on the
substantial Anti-Vibration Mountings (AVM) pillar stud. This
will limit vibration and extend the life of the AVM.

Best practice for efficient and effective ventilation is an air
intake that is located in the engine compartment/room
that is as low as possible, allowing cooler air to enter
below the engine an air outlet with an electric powered
extraction fan which should be located as high as possible
in the engine compartment/room maximising ventilation
and reducing ambient temperatures.
The cooler the engine compartment/room can be
maintained the more efficient the engine will perform.
The required air flow volumes in m3/min = 0.05 x engine
power in hp (naturally aspirated) or 0.06 x engine power
in hp turbocharged.

IMPORTANT!
Keep flexible mounts free from diesel fuel,
engine coolant & lubrication oil to prevent
deterioration.
IMPORTANT!
• Do not set the generating set feet high up
the flexible mount pillar stud. This will cause
excessive engine movement and vibration.
Pack steel shims under the flexible mount
and ensure that the flexible mounting is
securely bolted to the engine bearer.
• The pillar stud on the flexible mount is
secured into position by the lower locknut,
ensure this is fully tightened.
