Operation principle
The operation of the machine, for the generation of energy, develops through the following phases:
1. The fuel arrives at the endothermic engine where, by means of the combustion process, it is transformed into
mechanical energy;
2. Mechanical energy is converted by the alternator into electrical energy;
3. The self-priming water pump draws sea water for passage through the tube bundle of the heat exchanger;
4. The air leaving the heat exchanger is used for cooling the following components in succession:
• Engine oil sump;
• Alternator;
• Coolant contained in the engine cooling exchanger;
• Exhaust terminal.
5. Exhaust gases are expelled outside through the terminal.
PROTECTIONS OF THE MACHINE
The machine is protected by a multilayer berglass capsule, lined internally with sound-absorbing material, consisting
of:
- 1 lower containment element of the machine equipped with anti-vibration system.
- 2 upper elements with interlocking proles, held together by silicone elastic bands.

2. OPERATING CONDITIONS
2.1 CONTAINMENT COMPARTMENT
This type of machine has been designed and manufactured to operate on board boats and in a well ventilated and
closed compartment, where there are no danger of explosion or re.
The Marine generator containment compartment must ensure minimum distances for correct air replacement.
2.2 MINIMUM AIR CHANGE DISTANCE
The image below shows the minimum recommended distances to be kept around the machine. The environment in
which the machine is installed must be naturally ventilated and have more than one opening to the outside. Select a
compartment that allows adequate air ow for the engine air intake.
2 Operating conditions
2.3 CHARACTERISTICS OF THE OPERATING ENVIRONMENT
This machine has been designed and realized to work only at the environmental conditions listed here below:
• Area temperature range: value between +5 °C and +40 °C.
• Maximum RH without condensation: 90% at 20°C.
Minimum air change distance
2.4 LIGHTING
The machine, once installed, must have sufcient natural light to ensure adequate visibility to the operator during
maintenance.
It is the task of the operator to equip the boat with suitable articial lighting systems such as to ensure adequate lighting
on the machine in case of maintenance work. The lighting must be uniform and ensure good visibility.
Work with insufcient natural light may require the use of local lighting xtures. It is to be remembered that the devices
must not be able to generate additional risks.
2.5 VIBRATION EMISSION
The entire machine has been designed and manufactured to limit the generation and distribution of vibrations produced
during normal operation, which could compromise the stability and/or operation of the machine. In particular, Paguro
generators use a dual system to minimize the vibrations transmitted to the hull:
1. 1 internal system consisting of:
- 2 anti-vibration brackets.
- 4 soft anti-vibration supports and respective anti-vibration xing screws.
2. 1 external system consisting of:
- 2 anti-vibration brackets on which the entire machine rests.
- 4 anti-vibration semi-elastic supports and the respective anti-vibration xing screws.
Bracket and anti-vibration support (outside machine)
Bracket and anti-vibration support (inside machine)
Example - Generator compartment

NOTE: The external anti-vibration supports already have holes for securing the machine to the boat.
In addition, in order to attenuate the vibrations transmitted to the boat and consequently to reduce the sound level
further, it is recommended to install, under the machine, a wooden platform, which in turn should be installed on soft
anti-vibration supports.
This platform must have the following requirements:
- At least 30 mm thickness.
- Own weight over 10 kg to behave like a mass in opposition to the vibrations induced by the engine.
Abnormal vibrations reveal mechanical problems (e.g. loose belts).
In this case you must intervene following the maintenance procedures described in this manual (in particular see
Chap. 10 “Maintenance”). If the phenomena continue, contact the manufacturer or the service centre listed in Chapter
“WARNINGS” immediately and stop the generator from operating until the problem is resolved.
Anti-vibration supports on platform
The vibration dampers of the oscillating platform (not included in supply) must not be aligned with the soft vibration
dampers located under the machine. Depending on the available space, the greater the distance between the vibration
dampers, the better the result is.
2.6 NOISE POWER EMISSION
The Paguro generator has been designed and manufactured to signicantly reduce the sound power level. In particular,
the machine adopts a soundproong capsule to limit the emission of the noise generated by the internal endothermic
engine into the surrounding environment. The capsule is made of berglass and is internally coated with sound-
absorbing material.
The maximum sound pressure value detected during the various samplings is less than 70 dB (A).
In any case, the factors determining the exposure level include the duration of the exposure, the characteristics of the
installation point and other adjacent sources of noise.
Abnormal sounds reveal mechanical problems (e.g. loose belts).
In this case you must intervene following the maintenance procedures described in this manual (in particular see
Chap. 10 “Maintenance”). If the phenomena continue, contact the Manufacturer or the service centre listed in chapter
“WARNINGS” immediately and stop the generator from operating until the problem is resolved.
Example - Sound-absorbing coating (internal lower side)

4.5 STORAGE
If there is a possibility that the machine will not be installed immediately, but has to be warehoused for a prolonged
period of time, the storage must take place in a sheltered environment, with a degree of protection appropriate for the
installed components. It is especially necessary to:
– check that the surface on which the machine will be positioned is able to support it adequately and that it is completely
level;
– always insert wooden platforms or other suitable platforms between the oor and the machine to prevent direct
contact with the oor surface;
– cover the machine with a sheet of plastic in order to protect it from dust, humidity or other elements that could
compromise its proper functioning;
– take the appropriate circulation and manoeuvring space to allow staff to carry out components harness and lifting
operations of the machine comfortably and safely.

VTE Srl
Via Luciano Lama, 5 - 33050 Fiumicello (UD) - Italy
Tel. [phone] - [email protected]
www. volpitecno.com
5.1 SET UP FOR INSTALLATION
Installation and commissioning of the generator must be carried out by a qualified technician or an
authorized company.
It is the task of the installer to provide an area suitable for the overall dimensions of the machine and to
carry out the necessary interventions for the correct and safe installation of the machine.
In the event of non-compliance with these indications, VTE S.r.l. will not be liable for any damage to the
machine or any subsequent performance that does not meet the technical specifications provided.
5.2 FIXING THE MACHINE
For correct machine functionality, a solid support must be provided to allow the machine to be xed on board the boat.
The support can be made of metal, wood or glass bre, and must meet the following conditions:
- being as low as possible, in order to avoid the occurrence of vibrations.
- maintaining the machine horizontal.
However, the following maximum inclinations are permitted if horizontal positioning is not possible due to lack of space
on the boat:
• Longitudinal: 20°
• Transverse: 25°
5. Installation of the machine

34 Mod. PAGURO P4MY - 5.5 MY • Date: 13.05.2022_Rev: 0.0 35
If possible, position the machine away from any splashes of water and vapours.
Choose a location that allows proper ventilation and easy access for maintenance.
If necessary, in order to reduce the vibrations generated by the endothermic engine, install a wooden
platform under the machine, which is in turn installed on soft anti-vibration supports (see par. 2.5
“Vibration emission”).
5.3 VENTILATION
Before proceeding with the installation of the machine, it is necessary to consider the need to allow a correct ow of
combustion air to the engine.
The hot air tends to go upwards, therefore the introduction of fresh air must be ensured in a low area of the machine
compartment and consequently the correct outow of the hot air in a high area of the same compartment must be
ensured.
The minimum distances to obtain correct ventilation of the machine are indicated in par. 2.2 “Minimum air change
distance”.
In order to ensure optimum air recirculation, it is also necessary to leave free the small ventilation holes provided on the
bottom of the soundproong capsule (lower protection) in order to allow the comburent air to pass from below.
Example - Lower capsule (internal side)
5.4 EXTERNAL CONNECTIONS
The location of the external connections is shown in the images below. The various connections must be made with
suitable diameters (as indicated in Chap. 1 “TECHNICAL SPECIFICATIONS”) not only to avoid leaks and drips, but also
to avoid unnecessary openings of the silencing capsule with
Key:
1. Gas/water mixture exhaust;
2. Diesel fuel supply and return;
3. PMG (permanent magnet alternator) cable outlet;
4. Multipole connector external inverter;
5. Battery positive and negative;
6. Siphon-break output and input.

5.5 EXHAUST SYSTEM INSTALLATION (on request)
The machine is supplied as standard with an exhaust, combustion gas and sea water terminal, on which an overtemperature
switch is installed.
It is the responsibility of the installer to design and install a suitable exhaust system in order to avoid
water returning to the engine with any sea conditions and any inclination of the boat.
Connect the drain terminal with a water approved tubing and pass the drain system through the hole in the machine
bottom capsule, as shown in the picture.
The installer MUST have a basic knowledge of the requirements of marine generator installations,
safety systems and seawater cooling systems.
Incorrect installation and design of the exhaust line can cause severe damage to the generator,
potentially causing the boat to sink.
Exhaust terminal
Holes for exhaust system piping passage
The VTE S.r.l. warranty does not cover errors and inaccuracies in the installation of the exhaust line.
VTE S.r.l. recommends the installation of the exhaust line of the “in-line” mufers.
The rst (waterlock) anti-siphon mufer must be installed in a lower position than the machine, in order to prevent
water from returning to the engine and to block the water in the subsequent pipes once the machine is stopped. It
is necessary to design the exhaust line so that there is a suitable jump between the exhaust manifold and the boat
passageway (end of the exhaust line).
WARNING! An exhaust line that is too long and/or has an incorrect slope can cause water to return to
the engine when the generator is switched off. The exhaust line connections must be secured in such a
way as to avoid any dripping.
The exhaust gases are fatal. Install a carbon monoxide warning near the machine and in a clearly visible
position.
5.5.1 Traditional system
To achieve a good reduction in exhaust line noise, N.3 exhaust mufers should be installed:
- the rst, anti-siphon (waterlock) prevents the return of water to the machine and reduces the acoustic emission by
50%;
- the second, intermediate silencer, reduces the acoustic output by a further 20%. The intermediate silencer must be
installed according to the slope shown in the diagram below in order to avoid excessive water return to the unit;
- the third, terminal, reduces the acoustic emission by 10% and prevents the entry of external water following waves
and sprays, etc…
An additional benet to exhaust silencing at the outlet is obtained by installing the end separator according to the
diagram on the following scheme. With the separation of the gas from the water to the discharge hole, the waste of
water, which derives from the water sprayed in a discontinuous way from the traditional plants, is eliminated, eliminating
the typical noise of the boats.

Traditional Plant diagram
System diagram with lack of space
In order to prevent water from returning to the engine, the anti-siphon mufer must be installed in a lower position
than the generator, so that the exhaust pipe between the machine and the mufer has a downward slope. It is in fact
necessary that there is a slope and the ow of water from the machine has a natural and forced downward path, so that
when the machine is switched off, the cooling water present ows back toward the mufer.
The pipe from the machine to the anti-siphon muffler must be as short as possible (but not less than 30
cm) in order to reduce exhaust noise.
5.5.2 On-board system with space shortage
In case of absolute lack of space for the installation of the mufers, the realization of the loop with the exhaust pipe (see
gure below), and anti-siphon mufer, ensures a good reduction of the acoustic emission and at the same time protects
the machine from sea water inlets.
5.5.3 On-board system with long exhaust line
In the case of a very long exhaust pipe, it is recommended to use an exhaust system with a double anti-siphon mufer
(see picture below). Due to the large amount of water in the exhaust line, the second anti-siphon mufer protects the
machine from water return.
System with long exhaust line diagram
5.6 INSTALLATION OF THE SUPPLY SYSTEM
The machine is powered by diesel fuel via the two (FUEL IN - FUEL OUT) fuel supply pipes on the lower capsule.
DO NOT use other types of fuel.
DIESEL FUEL SUPPLY:
The machine is usually connected to the main diesel tank of the boat. In this case, the machine supply line must come
from its own connection on the tank and not through a T on the propulsion engine supply pipe.
The pre-fuel pump on the engine is capable of drawing up diesel fuel to a height of 1 meter without length restrictions.
DIESEL FUEL RETURN:
The diesel return line must be connected to the top of the tank in the same way as the supply.
This must be done when the tank is located under the machine. This precaution will help prevent starting difculties
due to deaeration of the system.
