2.1
GENERAL
To ensure reliability and durability of the equipment, it is very
important that the installation is carried out with the utmost
care and attention. To avoid problems, such as temperature
problems, noise levels, vibration, etc. the instructions set out in
this manual must be followed and all installation work must be
carried out professionally.
2.2
LOCATION
When looking for a proper place for a generator in a vehicle all
relevant aspects have to be taken into account
•
Accessibility
•
Solid foundation
•
Space to mount the radiators (refer to 2.5.2)
•
Space to mount the exhaust (refer to 2.5.3)
•
A way to fit the fuel lines
Since WhisperPower generating sets have extremely compact
dimensions, they can be installed in tight locations. Please
consider that even almost maintenance-free machinery must
still remain accessible.
When selecting the location area in which to mount the
generating set, make sure there is sufficient room to carry out
any maintenance work. The unit must be easily accessible on
the service side and on the distribution side to have access to
the V-belt.
All models can be serviced from one side. Note that oil filling
can be only done on the top side of the engine. Cooling liquid
can be filled via the expansion tank.
The top of the engine (rocker cover) has to be accessible for
adjustment of the valve clearance.
Please also note that in spite of the automatic oil pressure
sensor it is still essential that the oil level is checked regularly.

INSTRUCTIONS FOR OPTIMUM SOUND AND
VIBRATION INSULATION
Position the generating set as low as possible in the vehicle. The
generating set is already secured to the base frame by means of
flexible engine mountings. The base frame is mounted to the
chassis of the vehicle on a second set of rubber mountings that
is included in the delivery. Use the included mounting template
to determine the mounting spots.
When it is possible to mount the unit directly on the chassis of
the vehicle, this may help prevent vibrations by resonance.
2.3.1
Further recommendations
WhisperPower generating sets are standard equipped with a
sound cover. This sound cover has been designed to give
effective sound insulation. For optimum sound and vibration
dampening, the following factors should be considered.
Most important is the structure on which the generator is
1
placed to be stiff. Directly below the rubber mountings the
structure should be supported vertically to the chassis of
the vehicle.
2
In larger vehicles a separate and insulated space for the
generator will help to dampen the noise even further
3
Avoid mounting the generating set in close proximity to
thin walls or floors that may cause resonance.
4
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 be at least be
reinforced with stiffening struts or ribbing. If possible,
holes should be drilled 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.
Never connect the base of the generating set directly to
5
walls or tanks.
