6.1 GENERAL

The Moatti automatic fuel oil filter should be installed in the fuel oilsystem in accordance with good working practices. Pay attention tothe recommendations and only use specified materials.

CAUTION:

Ensure that the equipment is installed inaccording to the instructions given in thismanual.

Note:

Ensure that the pressure drop indicator isconnected to the control system of the engine.

CAUTION:

Before the first operation through the automaticfilter, ensure that any possible contaminantsfrom the installation work have been removedfrom the fuel oil system.

Note:

Do not «flush» the fuel oil system andpipework through the automatic filter. Seechapter "FLUSHING THE SYSTEM".

6.2 THE FILTER IN THE SYSTEM

The filter should be installed in the fuel oil system in accordance withone of the flow sheets in section 2.3.

6.3 FILTER LOCATION SPECIFICATIONS

6.3.1 Mounting

The filter can be installed in any direction. However the most commondirection is vertical.

6.3.3 Accessible location

Specification

The filter should be installed in such a way to ensurethat:

(i) the drain cock (with its elbow) can easily bereached and operated.

(ii) the value on the pressure drop indicator caneasily be observed.

6.4 SYSTEM PIPING CONNECTIONS

Specification

Ensure that the pipes to and from the filter match theoil flow direction in the filter.

A =Inlet

F =Outlet

P =Backflushed oil outlet

The filter is delivered with the necessary counterflanges, gaskets and bolts.

Specification

•

Ensure that the blind flanges (between theflanges and the counter flanges) are removedwhen the pipework has been connected.

•

Shut-off valve (V3) must be installed in the back-flushed oil outlet.

•

The pipe for the backflushed oil must be directlyconnected to the deaerator (see figure “Hotside“ on the following pages) or to the suctionside of the supply pump (see figure “Cold side“on the following pages). This line should be ofequal or greater diameter than the outlet andshould be a short pipe with a minimum numberof bends and no restrictions. No other connections should be made to thispipe.

•

Shut-off valves (V4) on the heating pipes mustbe installed. Either at the filter or at the “inlet” ofthe booster module.

•

The drain cock should be connected to the drainpipe via a funnel.

•

The drain from the diversion chamber should belead to a sludge tank.

•

A pressure regulating valve (V21) must beinstalled in the filter outlet if the following isvalid :

Filter located in the «circulating part» («Hot side»)

+

Engine is equipped with built-on feed pump

or

Fuel oil pressure at engine inlet (PE) is less than 6 bar with a deaerator pressure

(P3) of 4 bar.

see figure “Hot side“ on the following pages

By means of valve V21 the pressure at filter outlet(P2) can be increased which makes it possible toadjust the P2-P3 up to an optimal value of 3 to 5 bar.

Valve V21 should not be touched during stop andstart of the filtration.

6.5 CONNECTION OF THE ELECTRIC MOTOR

The control of the electric motor should be installed in accordance with the following diagram :

Specification :

The wire between the thermal relay and the electric motor should should be of the marine type, with across section of : 3 x 1.5mm

2

, and an external diameter of ~ 12mm.The length of the wire between the thermal relay and the electric motor should not exceed 10 meter.

Remark :

KX1 and KX2 may not exist on some installations

6.6 CONNECTION OF THE PRESSURE DROP INDICATOR

CAUTION:

The electrical contactor (E) ofthe pressure drop indicatorMUST be connected to thecontrol system of the engine.Trouble shooting MUST bestarted immediately a pressuredrop alarm is detected.

6.7 FLUSHING THE SYSTEM

During installation there is a risk that various types ofcontaminants may "find their way" into the system.

To prevent operating problems (see chapter"TROUBLE SHOOTING" in the

Instruction Book

)these contaminants must be flushed out of thesystem before the automatic filter is used to filter anyoil.

This "flushing" procedure must be made through aspecial flushing filter (which is installed temporarilyfor this) or through the manual by-pass filter.

CAUTION:

Never use the automatic filter inthe "flushing" procedure.
