Description of Filter Operation
Filtering process:
The MEGA ABF-40,000 FILTER is a sophisticated yet easy-to-operate automatic filter, with a self-cleaning mechanism driven by
electric motors. The MEGA ABF consists of four filter unit and is designed to work with various types of screens in filtration degrees
from 200 to 3500 micron, and is available in 16", 18", 20", 24" and 28”inlet/outlet diameters.
The water enters through the inlet pipe into the fine screens from the inside out. The "filtration cake" accumulates on the fine
screen surface and causes head loss to develop.
Self-cleaning process:
The MEGA ABF-40,000 FILTER starts the self-cleaning process when the pressure differential across the screens reaches a pre-set
value or a predetermined lapse of time.
Cleaning of the filter element is carried out by opening a flushing valve located on the housing lid and starting the electric motor,
which revolves 2 stainless steel brushes on the inside of the filtration cylinder.
The particles trapped on the cylinder are dislodged by the revolving brushes and flushed out through the open flushing valve.
The cleaning operation duration is approximately 15 seconds per screen.
The service flow of the filtered water is continuous during the cleaning cycle.
The electric control board which is supplied with the filter controls the automatic operation of the filter.
Different modes of filtration:
The filtration system may be found in one of the following modes:
1. Filtering mode: This is the normal function condition. Flushing doesn’t occur & the power light on the control board is lit.
2. Flushing mode: A mode in which the flushing process is in progress. The motors and the exhaust valves open according to the
program.
3. Malfunction mode: During malfunction mode the self-cleaning operation is stopped, the malfunction light on the control board
is turned on and an external dry contact output is activated.
The filtration system may enter a malfunction mode in the following cases:
1st. When there is a continuous signal from the pressure differential switch for duration of more than 5 minutes. This means that
the self-cleaning process is not successful (Could be set differently by changing the settings of the fault timer TAL, inside
control board).
2nd. When one of the motor-protectors is activated, manually, or due to overload (in such case the remaining filter elements
continue to operate).

Mega ABF 40000 IL 910101-001027 / 08.2019 Page 10 of 22
Initiation of self-cleaning:
The filter enters the self-cleaning process as a result of any of the following causes:
1. A signal from the Pressure Differential Switch (PDS) - The PDS mounted on the filter body, sends a dry contact when the pressure
differential across the screen reaches the pre-set value (usually 0.5 bar / 7 psi). The control board registers the signal and
operates the flushing process according to its program. (Closing the manometer valve connected to the low pressure of the PDS
for 5 seconds also causes the filter to start flushing.)
2. Manually pressing the "TEST" push button at the control board.
3. The TIMER feature of the control board allows operation of self-cleaning process at pre-set time intervals, independent off the
head loss factor. The timer resets after every flushing cycle.
Cleaning cycle stages of single filtration unit:
1) The exhaust valve opens to the atmosphere.
2) The motor starts rotating the shaft with the brushes, for approximately 15 seconds.
3) The exhaust valve closes.
4) The motor stops.
Cleaning cycle of the MEGA ABF unit:
The four filter units are flushing in sequence; one unit at a time.
A common PD Switch provides the signal for flushing the entire system.
1) Unit #1 flushes as described above.
2) The exhaust valve of unit #2 opens as soon as the cleaning cycle of unit #1 ends.
3) The cycle ends when unit #4 has ended its cycle
During the self-cleaning process there is no interruption of the service flow and the PDS constantly monitors the pressure differential
between the inlet and the outlet of the filter.

Installation
Design recommendations
1. If flow increases and pressure drops dramatically for a long period of time during network filling-up, it is recommended that a
pressure sustaining valve is installed downstream of the filter. The pressure sustaining valve will ensure a controlled filling-up
of the line.
2. If continual water flow is essential even during maintenance period, it is recommended that a manual or automatic by-pass is
installed, and the isolating valves will be used to isolate each filter.
3. In places where there is an expected temporary worsening of water quality, it is possible to operate an emergency flushing
program. In order to do so, a hydraulic controlled valve has to be installed downstream of the filter. For details, please
consult the manufacturer.
Installation instructions
1. Before beginning the installation process, carefully read the safety instructions chapter of this document and make sure that
all the workers at the installation site are fully aware of and comply with, these and any other local safety instructions.
2. Select a convenient location for the installation of the filter where operation and maintenance will be optimal. It is
recommended that a standard and safe lifting auxiliary is available for maintenance.
3. Install the filter horizontally. Please note the minimum clearance (Not including a crane) required in order to allow
disassembly of the unit.
4. Ensure that the direction of flow is aligned with the arrows marked on the filter housing.
5. Installation of a mechanical non-return valve downstream of the filter is required.
6. If possible, prior to installing the filter, thoroughly flush the main line at the connection point in order to remove large objects
that may damage the filter’s internal mechanism.
7. Install a drainage pipe to the exhaust valve. Minimum 2" diameter for a maximum pipe length of 20 meters (60 feet), for
longer drainage, 3" pipe diameter must be used for a maximum length of 40 meters (120 feet). Please note that no restriction
is allowed on the drainage pipe for a flow of 7.5 m3/h (33 US-gpm). For special applications, please consult the manufacturer.
8. If the system is designed to operate with working pressure higher than 6 bar (85 psi), it is recommended that a manual
valve is installed on the exhaust pipe, in order to enable regulation of the flushing flow rate & pressure.
9. The user should arrange suitable lighting in the vicinity of the filter to enable good visibility and safe maintenance.
10. The user should arrange suitable platforms and safety barriers to enable easy access to the filter without climbing on pipes
and other equipment. All such equipment should comply with the safety clauses of the relevant local standards.
IMPORTANT!!
•Prevent static back pressure or reverse flow through the filter.
•Install a non-return valve at the outlet of the filter.
•Install a manual or a hydraulic valve downstream of the filter.
Electric wiring
1. All electrical works at the installation site must be done by a qualified and authorized electrician only. Make sure that this
electrician is fully aware of all the relevant safety instructions.
2. Install the control board in a dry and protected place (In out-door installation sites make sure to use a special control board
for out-door installation).
3. Power connection to the control board:
a. Connect a three-phase voltage source through a semi-automatic switch, or 16 Amp. fuse to the L1 L2 L3 inlet at the
terminal strip in the control board.
b. Earth the control board.
4. Power connection to the motor:
Connect the drive units to the control panel by means of a cable of 4 x 1.5mm2 for a distance of up to 5m. For distance of up
to 10m a cable of 4 x 2.5mm2 should be used.

Mega ABF 40000 IL 910101-001027 / 08.2019 Page 12 of 22
Use a long enough cable to allow the drive units to be removed and placed near the filter for maintenance, without having to
disconnect them from the cable. (It is recommended that this installation meets or exceeds local or national electrical codes,
this is a "high" voltage connection).
5. Control wiring:
The connection between the control junction box and the control board should be by 6 x 1.5 mm 2 (16 AWG) wire in flex-
conduct. The numbers on the terminals in the board and in the junction box are identical.
Commissioning, Start-Up and First Operation
1. Before starting-up the filter read the safety instruction as appear at chapter 2 of this document and pay special attention to the
commissioning safety instructions.
2. Inspect the filter’s installation and make sure that it is installed in accordance with the official installation drawings.
3. Verify (by authorized electrician only) that the electric wiring is correct and complies with the enclosed drawings. Make sure
that the electrical start-up operation is done by an authorized electrician only.
4. Switch "OFF" motor protectors E1 - E4
5. Switch "ON" all circuit breakers.
6. Set selector ITSW to the off position (PD only).
7. Switch on E1 and watch the rotation direction of the motor of filter unit #1. If the motor rotates counterclockwise, stop it
immediately by turning E1 to the off position. Change the motor direction by switching between two phases.
8. Repeat the above with filter elements #2, 3 and 4.
9. Press the "TEST" push button and verify that the filters are functioning according to the sequence described in this document.
10. Open the water supply and pressurize the filter. It is highly recommended that first "wet" operation is done with static
pressure and no flow i.e. the outlet valve is open and the by-pass of the system is open.
11. Operate and simulate the different events by closing the 1/4" Manometer Valves of the PD switch for 5 seconds.
12. If everything is functioning as described, open the outlet valves of the filter and gradually, close the by-pass valve.
13. Set it to 4 - 8 hours and turn selector ITSW to the on position (PD & Time). Follow and monitor the functioning of the filtration
system, change its setting if required.

Mega ABF 40000 IL 910101-001027 / 08.2019 Page 13 of 22
Electrical Control System Description
The Mega ABF control board monitors and operates the filter self-cleaning process. The self-cleaning process includes simultaneous
operation of the motor and opening of the exhaust valve. The control board will cause the initiation of a flushing cycle as a result of
each of the following reasons:
1. Signal from the PDS.
2. Manual initiation by TEST / RESET push-button.
3. Internal timer, up to 30 hours.
During operation the Main switch, the Motor Protector and the F2 Circuit Breaker must be "ON". In this condition the power pilot
light is lit.
Flushing by PDS:
The signal duration from the PDS should be longer than the preset time in timer T0. It is recommended to set it to 3-5 seconds.
This delay will prevent the filter from entering into flushing mode as a result of a momentary signal from the PDS.
Manual Operation:
Quick pressing on the TEST / RESET push button will cause operation of self-cleaning.
Flushing according to Time:
The timer is located inside the control board and is marked "T2".It is possible to set it for intervals from a few minutes up to 30
hours.
To cancel the option of flushing by timer, turn off the SW-1 switch.
Timer T1 determines the minimum flushing duration. It is recommended that flushing duration be set to 15 seconds.
Fault Mode:
The control board is equipped with a protection circuit. It will cause the filter to enter a "fault" mode if continuous signal from the
PDS is received for duration longer than the preset time in TAL. This means that in case that the filter does not manage to clean
itself; the PDS will continue to send a signal. When the TAL time elapses, flushing stops, "fault" pilot light is lit and fault relay is
activated. It is possible to use this relay also for an alarm, automatic by-pass, etc.
To come out of fault mode, press the TEST / RESET push-button.
The recommended preset time for TAL is 5 minutes.
It is possible to order control boards with additional features such as sequential operation of a few filters in a battery, flushing
counter, etc.
Follow the drawing in this manual for proper wiring of the control board to the filter.
