1 INSTALLATION
1.1 GENERAL
This installation manual is valid for the following models:
Part
number Description
41105055 M-SQ7 120/240V 1800RPM
41105056 M-SQ7 120/240V 1800RPM -ungrounded
For other models see our website: www.whisperpower.eu.
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.
1.2 LOCATION
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
Please also note that in spite of the automatic oil pressure
sensor it is still essential that the oil level is checked
regularly.
1.3 INSTRUCTIONS FOR OPTIMAL SOUND
AND VIBRATION INSULATION
Position the generating set as low as possible in the
vessel. As the generating set is already secured to the
base frame by means of flexible engine mountings, the
frame must be mounted directly, without additional
vibration dampers, to the vessel’s main structure.
WhisperPower generating sets are standard equipped with
a 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 Most important is the structure on which the generator
is places to be stiff. Directly below the rubber
mountings the structure should be supported vertically
to the superstructure of the ship.
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 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.
4 Never connect the base of the generating set directly
to bulkheads or tanks.

1.4 VENTILATION
The generating set normally draws air from the engine
room. Engine rooms with natural ventilation must have
vent 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 16 sq inch (100 cm2)
is required.
A "sealed" engine compartment must have a good
extraction ventilator to maintain reasonable engine room
temperatures. High temperature of intake air reduces
engine performance and increases engine coolant
temperatures. Air temperatures above 104°F (40°C)
reduce the engine power by 1% for each 5°F of rise. To
minimise these effects the engine room temperature must
not be more than 27ºF (15 ºC) above the outside ambient
air temperature.
Apply a combination of ventilators, blowers and air intake
ducting to meet the temperature limit. The air inlet ducts
should run to the bottom of the engine room to clear fumes
from the bilge and to circulate fresh air. Air outlets should
be at the top of the engine room to remove the hottest air.
An engine room blower should be used as an extraction
ventilator to remove air from the engine room.
In cases where it is impossible to meet the above
mentioned temperature limit by using machine room
ventilation, connections are to be made for an air inlet
directly to the enclosure. With these connections the
generating set can be directly connected to an air duct.
Air inlets should be louvered, where appropriate, to protect
the engine room and to protect the generating set from
water spray. As an extra precaution, the fitting of a cowl
ventilator with a cover box located as high as possible, is
recommended.
1.5 CONNECTIONS
The generating set comes supplied with all supply lines
and output cable (i.e. electric cables, cooling water
connections, exhaust, fuel lines etc.) already connected to
the engine and generator. The supply lines are fed through
the capsule’s front base. The connections are marked as
shown in figure 2
All electrical connections, cable types and sizes must
comply with the appropriate national regulations. Supplied
cables are rated for ambient temperatures up to 158ºF
(70°C). If the cables are required to meet higher
temperature requirements, they must be run through
conduits.
ATTENTION!
Before working (installation) on the system
read the section safety instructions.
