1 GENERAL INFORMATION

FAILURE TO RESPECT THE SPECIFICATIONS CONTAINED IN THIS INSTALLATION MANUAL

WILL RESULT IN FORFEITURE OF THE GUARANTEE ON THE PRODUCT.

Carefully consult this manual before proceeding with any operation on the generator.

1.1 Purpose and field of application of the manual

Thank you for choosing a mase product.

This manual has been drawn up by the manufacturer with the purpose of providing essential information and

instructions for proper installation in conditions of safety and constitutes an integral part of the generator equipment.

The manual must be kept safely, protected from any agent which might damage it, for the entire life of the generator

and must accompany the generator if transferred to another user or owner.

The information contained in the manual is addressed to all those persons involved in the operating life cycle of the

generator, and is necessary to inform both those who effectively carry out the different operations and those who

co-ordinate the activities, arrange the necessary logistics and regulate access to the place where the generator will

be installed and operated.

The manual defines the purpose for which the generator was constructed and contains all the information necessary

to guarantee safe and proper use.

Constant observance of the instructions contained in this manual guarantees the safety of the operator, operating

economy and a longer life of the generator.

It is warmly recommended to carefully read the contents of this manual and the reference documents; only thus

can regular functioning and reliability of the generator be guaranteed over time, and protection against damage to

persons or things.

The drawings are provided by way of example. Even if the generator in your possession differs considerably from

the illustrations contained in this manual, the safety of the generator and the information provided are nevertheless

guaranteed.

To facilitate consultation, it has been divided into sections identifying the main concepts; for a quick look at the

topics, consult the index.

Note. The information contained in this publication is correct at the time of printing. The manufacturer in his pursuit

of a policy of constant development and upgrading of the product reserves the right to make modifications without

prior notice.

1.2 Symbols

Those parts of the text not to be ignored are highlighted in bold type preceded by a symbol, as illustrated and

defined below.

Indicates that particular attention must be paid in order to prevent running into serious danger

which could lead to death or possible hazards to the health of personnel.

A condition which may occur during the lifetime of a product, system or plant considered at risk

regarding damage to persons, property, the environment or economic loss.

Indicates that particular attention must be paid in order to prevent serious consequences which

could result in damage to tangible goods, such as the resources or the product.

Instructions of particular importance.

2 PRESCRIPTIONS FOR SAFETY DURING INSTALLATION AND SETUP

• The personnel in charge of installation and starting of the generator must always wear a protective helmet; wear

safety shoes and overalls.

• Immediately change wet overalls.

• Use protective gloves.

• Do not leave disassembled parts, tools or anything else not forming part of the system on or near the engine.

• Never leave inflammable liquids or cloths soaked in inflammable liquids in proximity of the generator, near electric

equipment, (including lamps), or parts of the electrical system.

• Take the necessary precautions to prevent the danger of electrocution.

3 INSTALLATION

3.1 Characteristics of the installation space

The generator must be installed in a sufficiently

ventilated room, able to assure 800 m3/h air, which

corresponds to the quantity of air required for alternator

cooling and engine combustion.

The space must be separate and acoustically insulated

from living areas.

The generator should be positioned so that normal

maintenance operations can easily be carried out.

Propulsion motors are recommended for installation in

the area as long as they comply with the above-

mentioned conditions.

3.2 Fastening the unit to the ground

To fasten the unit securely, a base should be installed

to absorb vibrations and support the weight.

Drill holes in the base according to the instructions in

Fig. 1.

3.3 Ventilation

The generator is equipped with an internal forced cooling

system by means of the alternator fan.

The quantity of air required for alternator cooling and

engine combustion is aspirated through the opening

shown in Fig. 2, ref. A, and is expelled through the two

side vents shown in Fig. 2, ref. B. Therefore, ensure

that these openings are always clear.

4 COOLING WATER CIRCUIT

The engine is cooled by an closed circuit system heat

exchanger.

On installation a sea water feed circuit should be fitted

for cooling and a waste system to expel the mixture of

flue gas and water.

4.1 Sea water feed system

Boats usually use one of two systems to collect water,

(Fig. 7).

1Direct infeed system.

2System with baffle.

mase recommends the direct infeed system, (Fig. 7,

ref. 1), since this system prevents water under pressure

entering the suction ducts and instead forms a pressure

which can easily be overcome by the water pump of

the electric generator.

Do not apply any type of protective hood to the direct

infeed system.

The baffle system might cause the following problems.

aIf it is installed with the slots facing the prow.

In this case, during navigation and with the electric

generator off, pressure is accumulated in the water

infeed duct which might cause the system to fill up,

even as far as the exhaust port, allowing water to

enter the cylinders.

bIf it is installed with the slots facing the stern.

In this case a depression might accumulate in the

water infeed duct during navigation, preventing the

water pump from starting up the cooling plant, or

limiting the capacity and subsequently causing the

electric generator to overheat.

• It is very important to respect the distances shown in

the installation diagrams.

• The mufflers, (Fig. 3 and 4, ref. 3), have the function

of collecting the water left in the exhaust pipes when

the generator engine is turned off and preventing that

it flows into the engine through the manifold and the

exhaust valve. For this reason it is essential to respect

the position of the muffler and the length of the pipes

as indicated in the installation diagram.

4.4 Components

The sea water intake system must be separate from the

one for the engines propelling the boat.

•Direct sea intake 1/2".

If the unit is installed more than 1 m above the water-

line, a check valve should be fitted after the sea intake,

(Fig. 5, ref. 1), to prevent the water circuit emptying when

the motor is off. If this empties, the rotor of the water

pump might be damaged during start up; for the same

reason, when the unit is first started up, the suction tube

from the valve to the pump should be filled manually.

•Ball tap 1/2", (general).

•Ball tap 1/2", (drainage). This is used to drain the

cooling system of the electric generator for general

maintenance or when a long period of inactivity is

expected.

•Water filter, (can be inspected). This must provide

efficient protection for the cooling circuit from the

entrance of mud, sand and seaweed.

Rate of flow: 25 l/min.

The filter mesh should be very fine. Mesh 2 - 470 micron

is recommended; other sizes do not give good filter

performance.

•Anti-siphon valve. This is a valve that brings the

cooling circuit back to atmospheric pressure when

the motor is turned off, thus avoiding the formation

of siphons. It’s use obligatory when the base of

the generator group is under the water line and it

must be positioned at least 50 cm above sea level,

(see Fig. 4).

Anti-siphon valve must be inserted between the inlet of

the sea water pump and mixing elbow as indicated in

Fig. 8.

The drainage duct of the anti-siphon valve must run

beneath the valve itself in order to prevent water

accumulating in the duct, which should always remain

empty to allow air to pass through when the unit is

switched off, (see Fig. 6).

It is recommended that the drainage pipe from the anti-

siphon valve be fed into the bilge, as small amounts of

water might be drained through it during normal

operation.

Run the pipes connected to the antisiphon valve through

the holes shown in Fig. 2, ref. 2.
