Sound dampening is extremely poor if the generating
set is mounted on a lightweight 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 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 walls or tanks.
VENTILATION
The generating set normally draws air from the engine
compartment. Engine compartment with natural ventilation
must have vent openings of adequate size and location to
enable the generating set to operate without overheating.
To allow sufficient of air within the temperature limits of the
generating set an opening of at least 100 cm2 is required.
A "sealed" engine compartment must have a good
extraction ventilator to maintain reasonable ambient
temperatures. The rated power of the generator is
measured at an ambient temperature of 25°C, each
temperature increase of 5°C reduces the engine power by
about 2%. In order to minimize these effects to the extent
that the operator can influence them, the temperature of the
engine compartment must not exceed the temperature of
the outside air by more than 15ºC.

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 and circulate fresh
air. Air outlets should be at the top of the engine
compartment to remove the hottest air. An engine
compartment blower should be used as an extraction
ventilator to remove air from the engine room.
CONNECTIONS
The generating set comes with all supply lines and output
cables (i.e. electric cables, coolant 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 figures
7 till 10.
All electrical connections, cable types and sizes must
comply with the appropriate national regulations. Supplied
cables are rated for ambient temperatures up to 70°C. If the
cables
are
requirements, they must be run through insulations.
ATTENTION!
Before working (installation) on the system
read the section safety instructions.
