Further recommendations

Whisper generating sets are standard equipped with a
"GRP" (Glass Reinforced Plastic) sound cover. The
canopy has been designed to give effective sound
insulation. For optimum sound and vibration dampening,
the following factors should be considered.
1 In larger vehicles a separate and insulated space for
the generator will help to damp the noise even further.
2 Avoid mounting the generating set in close proximity
to thin walls or floors that may cause resonance.
3 Sound dampening is extremely poor if the generating
set is mounted on a light weight flimsy surface such
as plywood which will only amplify vibrations. If
mounting on a thinner surface cannot be avoided, this
should at least be reinforced with stiffening struts or
ribbing. If possible, holes should be bored or cut
through the surface to help reduce the resonance.
Covering the surrounding walls and floors with a
heavy coating plus foam will certainly improve the
situation.
4 Never connect the base of the generating set directly
to bulkheads or tanks.

VENTILATION

The generating set normally draws combustion air from
the engine room. A full enclosure with natural ventilation
must have ventilation openings of adequate size and
location to enable the generating set to operate without
overheating. To allow an ample supply of air within the
temperature limits of the generating set an opening of at
least 100 cm2 is required. The radiator need its own
airflow. (Refer to par. 2.4.2 - 4).
Air inlets should be louvered, where appropriate, to protect
the generating set from water spray.

CONNECTIONS

The generating set comes with all supply lines and output
cables (i.e. electric cables, cooling water and oil
connections, exhaust, fuel lines etc.) already connected to
the engine and alternator. The supply lines are led through
the capsule's base. The connections are marked as shown
in fig. 5.
