For other models see our website: www.mastervolt.com
To ensure reliability and durability of the equi pment, 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 Whisper 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 si de 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. The generating set is already secured to the base frame by means of flexible engine mountings. The base frame can be mounted to the vessel’s main structure on a second set of rubber mountings that is included in the delivery. Use the included mounting template to determine the mounting spots.
1.3.1 Further recommendations
Whisper 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. See figure 1. 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 dampenin g 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 generati ng 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 ena ble 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 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. T o 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 base. The connections are marked as shown in fig. 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.

1.5.1 Fuel supply
1 FUEL TANK
Fuel tanks should be made of appropriate material such as (stainless) steel or plastic. Steel tanks should not be galvanised or painted inside. Condensation can occur in metal tanks when temperature changes. Therefore, water accumulates at the bottom of the tank and provisions should be made for the drainage of this water. The tank will need a filling connection, a return connection and an air ventilation connection which will require protection against water entry. Some official regulations do not allow connection points at the base of the fuel tank; in this instance connections are to be made at the top of the tank with internal tubing down to a few cm above the bottom of the tank.
2 FUEL LIFT PUMP
The generating set itself is equipped with a fuel lift pump; therefore the tank can be installed at a lower level than the generating set. The maximum suction height is 3 ft (1 m). If the pump has to lift the fuel higher than one meter an external electrical fuel lift pump must be installed. The control board is already prepared to connect an extra fuel pump.
3 FUEL PIPES
When the fuel tank is above the generating set we recommend ending the return line on the top of the tank. When the return is on the top - in case of a leakage the return line cannot overflow because of siphoning. One will only need a fuel cock in the fuel supply line (see figure 3). When the tank is below the generating set we recommend ending the return line on the bottom of the tank (A) below the inlet of the supply line (see figure 4)

Figure 4: Fuel supply
Both supply and return fuel pipe lines should be appropriate material and 5/16” (8 mm) outer diameter tubing. The quality of the tubing of fuel pipes could be submitted to local regulations depending on the application of the vessel. The fuel pipes can be plumbed to the flexible hoses which are on the generating set and have a connection to fit to 5/16” (8 mm) pipe. This fuel lines fulfils CE standards and are according to ISO 7840 A2. It is important to avoid bends in the pipes, as they could trap air bubbles. The return pipe should never be connected to the suction pipe or to other consumers of diesel fuel, such as the propulsion engine and heaters and return pipes
4 FUEL FILTERS
A fine fuel filter is installed which requires maintenance. Mastervolt advises to install an extra fuel filter/ water fuel separator near the fuel tank. Before starting your generating set for the first time follow the fuel system bleeding procedure in the users manual.

1.5.2 Cooling
Intercooling is based on a raw water pump, heat exchanger and water-injected exhaust. Cooling liquid in the internal cooling system is cooled in a heat exchanger by outboard water (raw water or seawater). After the raw water is warmed up in the heat exchanger it is dumped overboard by injecting it in the exhaust. The generating set should have its own sea water (coolant water) inlet and should not be connected to any other engine systems. A properly installed cooling system is critical to keep engine temperatures within an acceptable range. Ensure that the installation complies with the following installation instructions.
1 THE INTERNAL COOLING SYSTEM
The internal cooling system should be filled with cooling liquid. (Refer to the users manual 2.5.12) When the engine becomes hot the liquid expands and the system is pressurised. After the pressure becomes too high the release valve in the filling cap on the manifold opens an d the expanding liquid is pressed into the expansion tank that is in the delivery. Also the air in the system that is collected at the top of the manifold is released in this way. When the liquid cools down there will be under-pressure. Another valve opens and the liquid is sucked into the manifold again. This system works only when there is enough liquid initially. This has to be checked when commissioning the generator set. By filling up the expansion tank when necessary there will always be
enough liquid in the system. The hose that is in the delivery has to be connected to the connection on th e side of the filling cap. This hose is made of heat resistant plastic and is not sensitive for kinks.
The hose goes through a hole in the canopy
MA X .
Figure 5: Expansion tank placement
The tank has to be placed close to the generator. When it is mounted above the top of the manifold the liquid in the tank will be drained when the cap on the manifold is taken off. When keel cooling or radiator cooling is applied the system will not be pressurised. A cap without release valve should be applied. Refer to the special manua l for these applications.

2 RAW WATER SUPPLY
For raw water supply the following installation materials are required: -a skin fitting - a sea cock - a water strainer ­hoses and clamps. In order to keep the suc tion resistance in the line at a minimum, the sea water intake system (i.e. sea cock, trough-hull fitting, inlet filter, etc.) must have an inner diameter of at least 1” (25.4 mm) diameter. The suction hose should be kept as short as possible. Raw water plumbing should avoid bends as much as possible. Restriction of raw water flow, caused by kinked hoses, undersized pipes or connections, will reduce the engine cooling capability. This is the main cause for overheating of an engine. After running the generating set for the first time, check the coolant flow rate using a stopwatch and by holding a pail of a known volume under the wet-exhaust outlet. The flow rate should be according to the data in the users manual
3 INSTALLATION OF THROUGH HULL FITTING
It is good practice for yachts to use a hull inlet fitting with an integrated strainer (water scoop). For propulsion engines in motorboats the water scoop is often mounted against the sailing direction to induce more water intake for cooling.
This should not be done in the case of a generating set! When sailing at higher speeds, water will be forced into the inlet and your generating set will overflow! (see figure
7).
Figure 7 Installing water intake
On motorboats and on sailing boats the water scoop for a generating set should be fitted with the opening faced backwards to prevent water being forced in during sailing.

4 WATER STRAINER
Use an appropriate water strainer with connections of 1” (25.4 mm). Install the water strainer in a well accessible position, 2” (5 cm) above the waterline (see fig. 6, ref. 6).
5 SIPHON BREAKER (AIR VENT)
When the point of water injection is below the waterline, then -when the engine is stopped -there is a risk that the cooling water may enter the engine as a result of siphoning. To avoid this happening, the generating set is designed to accommodate a siphon breaker (air vent). See figure 2. In the standard delivery the connections are bypassed. Hose of 1" (25.4 mm) inner diameter should be used.
If the generating set cannot be mounted such that the bottom of the generating set is placed above the waterline, an air vent must be installed. Extend the water hose of the by-pass 24” (60 cm) above waterline and install an air vent. Ideally, the air vent should be mounted above the yacht keel center line (i.e. to minimize the influence of swaying on the water intake). See figure 6, ref. 5.
Fast motorboats will lay deeper when sailing at large speed and can cause pressure on the waterinlet. This should be avoided to prevent fleeding the engine.
If the air vent is clogged the water hoses will not be vented when the generating set has stopped and water can be forced into the engine. This leads to immediate engine problems and eventually severe damage!

Figure 8: Wrong siphon breaker hose routing
On the valve is a little hose to drain a little water that could be spilled from the valve. See figure 8. This hose s hould go down and may not end under water, because it should ventilate air into the valve to break the siphoning.
Check the air vent at regular intervals. Open, clean and lubricate the valve as required.

1.5.3 Exhaust system
Water is injected in the exhaust system of the generating set. In this way the cooling water that has passed the heat exchanger is mixed with the exhaust gases. Temperature and volume of the gases are thereby reduced considerably, so that a rubber exhaust hose can be used and the level of noise is reduced as well.
1 STANDARD EXHAUST SYSTEM INSTALLATION
The generating set exhaust system must remain completely independent and separate from the exhaust system of any other engine on board. A water lock prevents the generating set from being flooded by cooling water and should be installed as close to the generating set as possible. The lock must be large enough to hold th e entire water volume held in the hose from the top of the goose neck to the water lock. The water lock must be installed at the lowest point of the exhaust system (ref. to
fig. 10, ref. 1). The exhaust hose must have an inner diameter of 2½” (63 mm). The exhaust system must be installed so that the back pressure inside the exhaust does not exceed 0.07 bar (1psi – 70 cm watercolumn) and total length from the genearot to the top of the goose neck or or water/separator does not exceed 10 ft. (3m). (Refer to paragraph 5.4.3 of the users manual).
The exhaust hose descends from the capsule to the water lock. Then the hose rises via the "goose neck" to the through-hull exhaust outlet, situated minimum 2 inch (50 mm) above the water line (see fig. 10, ref 5.) The "goose neck" must be vertical and situated preferable along the ship’s keel center line. If the generating set is mounted less than 24" (60 cm) above the waterline, a "goose neck" must be installed to prevent the engine from overflowing. It is recommended to install an extra muffler close to the through-hull fitting.

2 "SUPER SILENT" EXHAUST SYSTEM
See figure 11. In order to reduce the noise level of the generating set to a minimum, an option to reduce the exhaust noise further (especially exhaust water splashing) is an exhaust/water separator. The exhaust/water separator allows the cooling water to be ejected throug h a line (figure 11, ref. A) separate from the exhaust fumes and also functions as a goose neck to prevent water from flooding the engine. If the exhaust/water separator is mounted more than 24” (60 cm) above the water level an additional goose neck is not required.
If the through-hull exhaust outlet has to be mounted far from the generating set an exhaust/water separator must definitely be installed (Total length of the exhaust piping from generator to top of goose neck (water separator) is more than 10ft / 3 m.) (ref. to fig. 12).
The sea water from the separator must then run down along the shortest possible path to the through-hull outlet. Only after the exhaust/water separator the exhaust hose may have a length of over 25 ft (7.5 m) (ref. to fig. 12)
However watertraps should be avoided as the fumes still contains water and this should not accumulate in bents (see figures 13a and 13b). An additional outlet exhaust muffler close to the hull outlet will help further to reduce noise emission

If the generating set and the exhaust system have been installed correctly, neighbouring boats will not be disturbe d by generating set noise. With the "super silent" exhaust system, generating set noises are almost inaudible. For optimal noise reduction, the sea water outlet from the exhaust/water separator (centre outlet on the unit) should be installed below the water level to eliminate noisy splashing of the effluent sea water. The through-hull outlet for the exhaust fumes should not direct the fumes directly toward the water surface as this will cause excessive noise (ref. to fig. 14).
Do not direct the outlet directly toward the water surface.

1.5.4 Digital Diesel Control system (12 Volt)
1 DIGITAL DIESEL CONTROL SYSTEM
The electrical control system is standard in 12 Volt with negative earth. Non- earth return is available as a n option for aluminium vessels to prevent corrosion.
All electrical wiring has been prepared on the generating set to the control panel prior to despatch from the factory. The engine is controlled by a very advanced microprocessor based system: Digital Diesel Control. The “black box” containing the microprocessor is located on top of the alternator. A local control panel is on the generating set.
Remote control
A remote control panel also containing a microprocessor is in the delivery. A 49ft (15 m) intermediate 8-pole communication cable is in the standard supply too (refer to fig. 15). If necessary an optional longer (up to 100ft / 30m) intermediate cable can be connected if the standard lengt h does not suit the required distance. When a longer distance than 100ft / 30m is required, consult the Mastervolt service department for advice.

One can mount the control panel after drilling a hole in the dashboard using the plastic cover. Refer to the dimensional drawing in paragraph 3.5. The panel without the plastic cover fits the Mastervision modular panel system.
More remote control panels (slave panels) can b e put in parallel by using the modular connectors on the back of the units. As a slave one can use the same panel offering all functions again. It is also possible to use an old or new type slave panel only to start and stop the generator. Old type remote panels and system panels can be connected by means of the green connector.
Pay attention to the colour codes as indicated in fig. 16 when fitting cable to the green connector. Some software versions in old system panels (supplied before ma y 2004) could conflict with the software in the DDC and an update of the software of the system panel could be necessary. When this is the case consult to the Mastervolt service department for advice.
When using the factory settings, installation is very simple: just plug the remote cable into the remote and the generator is ready to use. Refer to fig. 16.

Automatic start/stop
Mastervolt cannot be held responsible for damage caused by the unattended running generator using the auto-start/stop mode or interval mode
Using the auto-start/stop (interval) mode the generator can start unexpectedly. When working on the electrical system, the 3 Amp fuse must be removed from the control panel and the battery plus cable must be removed from the battery.
In the delivery are warning stickers to stick on several parts of the electric installation (transfer switch, distribution box, etc.) to warn for automatic start)
The Mastervolt Digital Diesel Control system offers several options for automatic starting and stopping.
Access to this menu and other menus could be blocked. For blocking and setting up this options refer to the APPENDIX of the DDC users manual. One of these options is to monitor a second battery (not being the starter battery) to start the generator automatically when the voltage of this battery drops belo w a certain setting. Other names for this second battery are “auxiliary battery”, “service battery”, ”users battery” or “consumers battery”. We will refer to this battery as “the second battery”(BAT2). In some menus the starter battery could be indicated as “the first battery” (BAT1). A sense wire to monitor the second battery should be connected (attention polarity!) to the connector on the back of the remote panel. Refer to fig. 17. The sense wires must be connected directly on the second battery before a main switch and be protected by a 3 Amps fuse. (Monitoring the generator starter battery does not require an extra sense connection)
Settings
When one want to apply other settings than the factory settings refer to the DDC users manual, especially to the APPENDIX.
2 STARTER BATTERY
For starting, the Whisper requires a battery with a capacity of at least 120 Ah. The generating set can be connected with the main engine battery or have its own battery. We strongly recommend the use of a separate battery for the generating set and to keep the wiring system for the propulsion engine and the domestic DC supply system completely separate and individually connected to separate batteries.

Figure 18 Starter battery
However, the negative of all the batteries on the vessel should be interconnected (when on earth) to avoid difference in the voltage level of the earth on different places causing trouble to electronic devices which might be in the system. The above recommendation is not valid for ships having the starter battery of the propulsion engine or other auxiliary equipment positive grounded. When this is the case an expert should be consulted. A battery switch may be used to interrupt the positive connection.
The starter battery is charged by the alternator on the engine. An additional battery charger will help to keep the battery in good condition when the generating set is not used. A battery charger is not included in the standard supply. A high efficiency battery charging unit can be ordered from Mastervolt which is able to charge both the ship’s main battery and the starter battery. Also a small charger can be used to charge the starter battery only, such as the IVO SMART 12/10. A battery switch and a charger are included in the battery installation kit, art. no. 50230220 (160Ah)

3 OTHER RECOMMENDATIONS AND WARNINGS
The battery should be secured for seagoing conditions and the terminals should be insulated. For extra safety the battery can be enclosed in a wooden, plastic, fiberglas etc. (non metal) box. Even when the earth return system is applied a negative battery cable should be use d and the vessel should not to be used as a conductor. The battery cables are supplied in a standard length of 5 ft. (1.5 m); if longer cables are required a larger cross sectional area should be considered to compensate for voltage reduction.
When two batteries are used in series to provide a 24 Volt supply system, never take off 12 Volt (starting) power from one of these batteries. This will result in severe damage to both batteries within a short time.
Disconnect the battery leads if electrical welding is to be carried out, otherwise damage will be caused to the diodes of the alternator.
As explosive hydrogen gases are discharged during charging, the battery should be located in a well ventilated room. Ensure that the supplied battery cable connectors are properly fitted and never remove during or shortly after charging as sparking can occur, which may ignite the hydrogen gasses.

The electric power supplied by the generator is of a high voltage and dangerous to people. Before working (installation) on the system read the sections on safety in the users manual.
Be sure that all electrical installations (including all safety systems) comply with all required regulations of the local authorities. All electrical safety/shutdown and circuit breaking systems have to be installed onboard as the generating set itself cannot be equipped with such equipment for every possible variation. The vessel’s power supply system should be suitable and safe for the AC voltage which is applied and the power that will be generated. Special attention has to be paid on dividing the system in branches which are fused individually. It is absolutely essential that each and every circuit in the on-board electrical system is properly installed by a qualified electrician.
The Whisper 30 ULTRA can be connected in the following ways:
- As a 120/240Volt split phase generator by an arrangement of the wiring in double DELTA.
- As a 3 x 120V/208 Volt three phase generator when the wires are arranged in double STAR. Here, 3x 208 Volt is available between the phases while 120 V olt is available between every phase and neutral.
See chapter 3 for connection of the AC-terminals. With all applications the installation should be laid out in such a way that there is a reasonable balance of load between the different phases.

1 FUSE
An input fuse (from the generating set to the electrical system) should be installed to protect the installed electrical system. Depending on the configuration of the AC wiring, the following maximum single phase currents apply:
AC configuration Maximum rating AC-fuse
120 / 240 Volt split phase 125 Amps 3 x 208 Volt three phase 48 Amps
The fuses must be of the slow reacting type. For electrical motors connected to the system, a motor protection switch must be installed
2 GROUNDING
With the U.S.A. models neutral of the AC alternator is grounded. The housing of the alternator and all other metal parts are grounded as well.
The connection between “neutral” and “ground” is necessary as part of a insulation failure protection system as commonly used in the U.S.A.
For safety reasons connect the main ships ground to negative point of the generating set start battery. When a ungrounded DC system or positive grounded DC system is applied the battery negative should not be connected to the main ships ground.
3 CABLE
For the power cable we recommend the use of 4 wire (split phase) or 5 wire (tri-phase) oil resistant cable with a sufficient cross sectional area. One wire for earth is included. For long cables it is recommended to apply cables with a larger cross section (refer to ISO 13297 annex A)
4 TRANSFER SWITCH
A power source selector switch much be installed bet ween the generating set and the ship’s electrical supply system. This switch must ensure that all AC consumers can be switched off at once. This switch should also be installed to keep the generating set and shore (grid) power systems separate. Transfer switches - to switch over from shore to ship or from generating set to inverter - should be well designed to switch over all wires including neutral (and not only phases or line) and there should be provisions with the aid of timers to prevent relays from clattering.
WARNING
In all situations the transfer switches between shore, inverter and generator should switch all connections, the phase lines (L) as wel as neutral (N).

2.2 Commission table
1 Check if a si phon breaker (air vent) is necessary and
has been installed 2 Open the seawater inlet valve and check all water
connections. Check if the strainer is installed on or
just above the seawater level.
3 Check if the exhaust system is properly installed.
Check maximum length of exhaust hose, diameter of exhaust hose, position of the water lock, maximum lift. Also check the minimum required height of 24 inch (60 cm) above sea level of the exhaust loop (goose neck).
4 Open the seawater outlet valve and check all water
connections. 5 Check the AC cables and the grounding. 6 Check if an AC breaker is installed before or after the
power source selector. When there is only a circuit
breaker, use it to disconnect the generating set from
the grid. 7 Check all DC connections, check if the battery switch/
circuit breaker is closed. 8 Open the fuel valve. Check if there are no air leaks in
the fuel supply line, and check if the lift of the fuel is
less than 3 ft. (1 meter). Check if there is no air in the
water fuel separator. 9 To bleed the fuel system use the manual pump by
turning the cap loose and pumping as long as
necessary to bleed the system 10 Check if the air intake in the canopy is not blocked. 11 Check the oil level and colour of the oil. Check the
coolant level 12 Start the engine by pushing the start button 13 Check when t he generating set is running, the delay
of 5 to 10 seconds in the power source selector
transfer. 14 Check voltage and frequency under ‘no load’
conditions. 15 Check voltage and frequency under ‘full load’
conditions. 16 Check if the battery charger of the generating set is
working (max. 14.5 Volt). 17 Close the sound shield and check the noise level. 18 Stop the generating set and check th e engine again
for leakages of oil, fuel or water.
