•
Diversion head (1)
•
Filter body (2)
The positioning of the filtering unit within the filter
housing creates two separate filter chambers. These
are:
•
Full-flow chamber (E)
•
Diversion chamber (L)
E
2
The full-flow chamber (E) contains the full-flow filter
elements that remove the harmful solids from the
fuel oil before it enters the engine.
F
The diversion chamber (L) contains the diversion
filter elements that filter the backflushed oil with its
solids from the full-flow chamber. The solids will
concentrate in this chamber and will be removed
from the fuel oil system by periodic draining.
A
The bottom of the filter body contains a heating
chamber.

FUNCTION DESCRIPTION
2.2.2
The filtering unit comprises a distributor (16) in the
centre which routes the incoming oil and controls the
filtering and backflushing procedure. This is covered
by a sleeve (18) over which two types of filter
element are placed. The bottom section houses the
finer full-flow filter elements (30) and the shorter top
section houses the coarser diversion filter elements
(29). Both sets of filter elements are located over
four assembling rods (31) to complete the filtering
unit. The bottom of the filtering unit is equipped with
a strainer (15).

16
Both types of filter element are made up from two
element halves. Each half comprises an aluminium
framework of 8 equal sectors separated by radial
ribs. Between each rib is a stainless steel filter
screen. When the pairs of filter elements are stacked
together they form 8 independent filtering columns in
each filter chamber.
•
The full-flow filter element screen is finer.
•
When the two filter halves are put together the
full-flow filter elements have the openings on the
outside (A) and the diversion filter elements
have the openings on the inside (B).
•
The diversion filter element internal diameter is
slightly smaller to prevent mixing of the
elements during assembly.

FUNCTION DESCRIPTION
2.4 DESIGN FEATURES
The Moatti automatic fuel oil filter is not a conventional type of
automatic filter. Conventional filters generally work on the principle that
the backflushing is initiated when the pressure drop across the filter
reaches a pre-set value. The Moatti filter is unique as it works on a
principle of continuous backflushing. Generally 15 to 20% of the filtered
oil is always backflushing one column of the filter elements .
The main features and advantages of the unique Moatti automatic fuel
oil filter are as follows:
•
Continuous backflushing
•
Disc-type filter elements
•
Filtered oil drives the continuous backflushing
•
No disposable filter elements
•
Constant pressure drop over the filter
•
Compact and lightweight design
2.4.1
Continuous backflushing
The Moatti automatic filter is continuously backflushed, column by
column. The backflushing is performed with filtered oil and the entire
filter surface is cleaned once every 1 to 3 minutes. This prevents
retained solids from sticking to the filter surface, ensuring a low and
constant pressure drop. Therefore, the need for manual cleaning of the
filter elements is reduced to a minimum.
2.4.2
Disc-type filter elements
The Moatti automatic filter is fitted with robust disc-type filter
elements.This design feature, together with the low and constant
pressure drop (from the continuous backflushing), eliminate the risk of
cracked filter elements.
2.4.3
Filtered oil drives the continuous backflushing
Filtered oil is used for backflushing of the filter elements.

562-IB3-06 fd04e47.fm
FUNCTION DESCRIPTION
2.4.4
No disposable filter elements
The Moatti automatic filter contains no disposable elements. The
backflushed solids are concentrated in the secondary filtration
chamber (diversion chamber) and are discharged by periodic draining.
2.4.5
Constant pressure drop over the filter
As the continuous backflushing process gives a constant pressure
drop it is possible to get an immediate indication from the pressure
drop indicator when something is wrong in the fuel oil system.
2.4.6
Compact and lightweight design
The design gives a simple compact, lightweight and reliable system
which is easy to install. It also provides increased possibilities for upgrading of existing installations

FUNCTION DESCRIPTION
2.5 PRINCIPLES OF OPERATION
2.5.1
Overview
The main principle of operation for the Moatti automatic fuel oil filter is
as follows:
•
The oil to be filtered is pumped through the filter and towards the
engine.
•
When the oil reaches the filter it first passes through a strainer.
This should remove any large foreign matter like pieces of rag
which may be left in the system after maintenance.
•
Once past the strainer the oil then passes through the full-flow
filter elements (where the solids are trapped) and towards the
engine. A part of the filtered oil (15 to 20 % of the capacity of the
filter) is used to backflush part of the full-flow filter elements.
•
The backflushed oil with solids from the full-flow chamber is led to
the diversion chamber where it is filtered again, before it is led
back to the deaerator (see 2.3.1 “Hot side“) or to the suction side
of the supply pump (see 2.3.2 “Cold side“).
•
The filter elements in the diversion chamber are backflushed (with
filtered oil) in the same manner as in the full-flow chamber.
•
The solids concentrated in the diversion chamber are discharged
from the system by periodic draining.
The whole filtering cycle can be considered as two phases:
Phase I
-
filtering in both chambers
backflushing in the full-flow chamber
Phase II
-
filtering in both chambers
backflushing in the diversion chamber

FUNCTION DESCRIPTION
2.5.2
Phase I
Filtering in the full-flow chamber
1.
Unfiltered oil enters the filter at (A) and flows through the strainer
(S) into the chamber (B) - the space between the distributor (C)
and the inner perimeter of the sleeve (J) on which the full-flow
filter elements (D) are mounted.
2.
The oil is distributed from this space through the full-flow filter
elements (D) in seven of the eight filtering columns (the eight
column is being backflushed). The solids are trapped on the inner
side of the elements in the seven filtering columns.

The filtered oil flows into the full-flow chamber (E) and is fed
through the filter outlet (F) towards the engine.

While the full-flow takes place in seven columns, solids are being
removed from the elements in the eighth column by backflushing
(from outside to inside of the column) using part of the filtered oil
from the full-flow chamber (E).

The backflushed oil with solids that enter the diversion chamber
(L) passes through six of the diversion filtering columns (from
outside to inside). The solids are trapped on the outside of the
diversion filter elements (M).
7.
The filtered backflushed oil flows through the return passage (N)
in the distributor to the “after”-diversion chamber (T) and is
recirculated from the backflushed oil outlet (P) to the deaerator
(see 2.3.1 “Hot side“) or to the suction side of the supply pump
(see 2.3.2 “Cold side“).

562-IB3-06 fd05e47.fm
FUNCTION DESCRIPTION
2.6 PRESSURE DROP INDICATOR
The inlet pressure P1 is taken before the strainer (15) and the outlet
pressure P2 is taken “after” the full-flow elements in the filter body (2).
Both monitoring points are fitted with isolator cocks and pipework to
connect them to the pressure drop indicator (44).
The pressure drop indicator shows the pressure drop ∆P (P1 - P2)
across the full-flow elements. Due to the continuous backflushing, ∆P
is constant during operation. It may vary from 0.2 to 0.4 bar.
If for any reason the filter starts to clog, the pressure drop will
increase. To prevent the filter becoming completely clogged the
pressure drop indicator is equipped with a preset alarm value (∆Palarm) of 0.8 bar.
If the pressure drop reaches the preset value, an electrical contact is
switched giving possibility for a signal to the control system of the
engine.
!
CAUTION:
The pressure drop indicator must be connected
to the engine control system for the ∆P-alarm to
safeguard the engine. On activation of a ∆Palarm, the trouble shooting activities must be
started immediately, see chapter 4.

TROUBLE SHOOTING
4.1 GENERAL
This chapter deals with the most common problems
when the filter does not work correctly or when the
∆P- alarm occurs. It will give the possible reasons for
the problems and actions to solve them.
The chapter is divided into the following main
sections :
•
Problems at initial start-up before ∆P-alarm
occurs, see section 4.2.
•
External leakage, see section 4.3.
•
Abnormal values on daily checks but no ∆Palarm, see section 4.4.
•
Problems with the ∆P-alarm activated, see
section 4.5.
Each section is divided into a general part and (if
necessary) into a specific part showing the
difference when the filter is located in the «circulating
part» («hot side») and in the «supply part» («cold
side»), see section 2.3.

TROUBLE SHOOTING
4.2 PROBLEMS AT INITIAL START-UP BEFORE A ∆P-ALARM OCCURS
4.2.1
No revolution of the electric motor
CAUSE
1. The power supply is not connected.
2. The automatic fuse (F2) in the electric
cabinet is tripped or in OFF position.
3. The Circuit breaker of the electric motor is
not switched on.
4. The Circuit breaker (F1) is not correctly
adjusted.
5. The capacitor (C1) in the electric cabinet is
out of operation.
6. An electrical connection is not correct.
7. Filtration temperature too low.
8. Partly clogged filter elements from “flushing”
through the filter.
ACTION
Verify that the disconnecting switch is in the
correct position and that the power supply is
respectively 110V AC or 220/230 V AC,
50/60 Hz.
Reset the automatic fuse (F2) to the ON
position.
Switch on the Circuit breaker (F1), pressing
the ON button.
Verify the preset intensity on the Circuit
breaker. The preset value is : 0.10 A
(220V AC), 0.20 A (110V AC).
Change the capacitor for one of the same
kind : 0.5 µF, 450V (220V AC), 2 µF, 450V
(110V AC).
Verify the electrical connections and the
correct wiring arrangement of the electric
motor.
Wait and see because the temperature will
probably increase. If it does not, verify the
heating valves V4, and check the fuel oil
heating system.
Switch off the electric motor on the control
panel, open the filter and clean the filter
elements and inlet strainer.
Notice ! Operation with no revolution of the electric motor will cause clogged filter elements.
See chapter 4.6 for electric diagrams.
!
WARNlNG:
Operation in the electric cabinet must be made by a certified electrician to
prevent electrical shocks.
NOTE !
Make sure that the capacitor is of the required capacity.
The capacity of the capacitor is written on the name plate of the electric motor.

MAINTENANCE
5.1 GENERAL
The design and the operating cycle of the filter
minimize the need for maintenance. However in
order to ensure reliable operation of the filter it has
to be
cleaned and inspected at regular intervals
(see 3.4.4).
Pressure drop alarms or breakdowns (see chapter 4)
may shorten this period. This chapter is divided into
the following sections :
•
Overhaul of the filter (5.2)
•
Overhaul of the electric motor (5.3)
•
After maintenance checks (5.4).
Sections 5.2 and 5.3 are structured as follows :
•
Tools and spares required
•
Disassembly procedures
•
Cleaning/inspection tasks
•
Assembly procedures.
Section 5.4 covers the checks that must be made
before the filter is put back into service. Required
new parts can be found in chapter 7, which contains
an illustrated parts list for the filter and electric motor.
A sample ordering form is included in the
appendices for ordering spare parts.

6.7 FLUSHING THE SYSTEM
During installation there is a risk that various types of
contaminants 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 the
system before the automatic filter is used to filter any
oil.
This "flushing" procedure must be made through a
special flushing filter (which is installed temporarily
for this).
