Construction
The standard housing of the filter is made of carbon steel with a 120 micron protective coating of
extra durable polyester, applied electro-statically and oven cured on a zinc-phosphate layer, for
maximum anti-corrosion protection both internally and externally.
Access to the internal parts of the filter is through the removable bolted cover.
All immersed parts are made of either plastic materials or non-corrosive metals to ensure many years
of trouble free operation.
For special applications; contact our representative for more information.

3 - Operating principle
A. Filtration mode
The raw water enters the filter inlet and passes through the coarse screen (1), the first stage of filtration.
This prevents passage of any large particles, which may damage the filter internals.
The water then flows through the inside of the filter to the inner side of the fine screen (2). The water
passes through the screen from inside out to the filtered water chamber (8) and flows out through the
outlet.
As the water passes through the fine screen, the solids accumulate creating a cake of dirt on the inner
surface of the screen; as a result the pressure drop across the screen increases, and when it
reaches a preset level (0.5 bar / 7.5 psi) the filter controller activates the self cleaning process.
B. Flushing mode
When flushing command is activated, the controller activates the flushing valve (6) and the gear motor
(5).
The pressure differential between the pressure inside the filter and at the open valve to the atmosphere
on the flushing chamber (4) creates a backflow effect at the unique SA nozzles (3), removing
accumulated solids from the screen to the drain.
The unique design of the SA nozzles achieves an increased suction and significantly decreasing the
water consumption during flushing, due to accurate contact point between the unique SA nozzle and
the screen.
The spiral motion of the nozzles cleans all the area of the screen.
The collector assembly is driven by electrical motor which rotates in one direction. The electrical motor
is connected through the collector (7) to a reversing mechanism (9) which enables a continuous linear
movement (back and forth) of the collector assembly.

UDI 5-3-2020
Maintenance Manual - 6Matic.
Subject to modifications
No liability accepted for errors or misprints
The flushing cycle will be activated on pressure differential, time or manual:
1. When the predetermined differential pressure between inlet and outlet of the filter is reached (as
preset on the D.P. Switch, usually 0.5 bar / 0.75 psi).
2. Time interval between one flushing to the next one (prefixed at the controller – can be changed by
the operator) - guarantees that the time passed from the last self-cleaning process will not be longer
than the pre-set value determined by the operator.
3. Manually initiated flushing by pressing a button on the controller.
Testing the pressure differential switch
When functioning correctly, creating a pressure drop by means of closing the valve (75) on the outlet
side of the filter, will result in a flushing cycle of the filter. Please note that during the closing of the
testvalve a small amount of water will be vented to the atmosphere.
C. Continuous flushing
The fine sintered screen is flushed continuously, through the suction nozzles. The flushing valve and
the worm-gear motor are activated continuously.
The "Continuous Flushing" is selected manually by the operator; the selector is located on the electrical
board.

4 - OPERATING MODES
This efficient filter is automatic and easy to operate.
When the optional PLC controller is installed the operating modes are as follows:
1. Filtration - The normal function of the filter
2. Automatic Flushing –Flushing of the screen through the suction nozzles, activated by time or
DP. The gear-motor and the flushing valve are activated simultaneously by the controller.
The Yellow Flushing light (on the control board) is ON.
The timer activates the flushing cycle according to pre-set time in the controller.
3. Continuous Flushing - Back flushing of the screen through the suction nozzles. The gear
motor and the flushing valve are activated continuously and the Yellow Flushing light is ON.
This manual mode is selected by the operator.
4. Malfunction mode – This mode takes place when the electric motor's overload is tripped.
Then the RED Fault Light (on the electrical board) is turned ON.

5 - Installation procedures
5.1 - Assembly prior to installation
The filter is normally supplied fully assembled.
Electrical connections will be done by authorized personnel only.
The filter may be installed in any position, although for ease of maintenance, horizontal installation is
recommended.
5.2 - Filter installation
1. For best results, the filter should be installed as near as possible to the system it is required to protect. However,
if low filter inlet pressure is a concern, either before or during flushing, the filter may need to be installed closer
to the pressure source.
2. Ensure that the upstream pipe size from the pressure source to the filter is equal to or greater than the filter’s
inlet size.
3. It is strongly recommended to install an isolation valve at the filter’s inlet, and a check valve, or an isolation
valve at the filter’s outlet.
4. An inlet isolation valve must be installed in situations where the pressure source cannot be shut down for
maintenance.
5. Inlet/outlet and by-pass valves must be installed in situations where a constant supply of water is required
downstream during filter servicing.
6. Ensure that the filter is mounted in the proper flow direction, as indicated by the arrows on the filter housing. As
a check, the inlet is closer to the cover end of the filter.
7. If a fixed drain pipe is installed on the auxillairy filter, use a funnel or other means so it will be visible if the valve
is opened or closed.
8. The mounting of the delivered 1”airvalve is strongly advised.
9. Ensure that sufficient space is provided around the filter for maintenance.
10. When the screen element is disassembled, reassembly as follows. Insert the screen element inside the filter
body. Open the service port cover (6) in order to get easy access to place the collector assembly in place. The
drive shaft (39) must be inserted into the shaft guide (19). Before doing so apply grease to the drive shaft.
11. When an acid-base injection is installed the injection location should be downstream from the filter.
Part numbers refer to the illustrated parts breakdown in chapter 11
5.3 - Drain line installation
A drain line should be attached to each flushing valve, as follows:
●The back pressure at the flush valve outlet should not exceed 0.3 bar (4.5 psi)
●Piping should be installed level or pitch down to avoid back-pressure.
●The open end of piping should be securely mounted to avoid vibrations during flushing cycle.

5.4 - Electrical installation
Technical electrical specifications:
●Reduction motor, see chapter 2 (Technical Specification). The electralmotor needs to installed with a current
overload protection acc. to EN 60204-1.
●Dp-switch: SPST 25W max 0,5 A + max. 240 VAC/VDC.
●Solenoid(s): 24 VAC-D 50/60 Hz 2,2W
Filter control:
●Flush modes:
qAutomatic (triggered by pressure difference and by time)
qManual
Automatic flush mode
●The flushing of the filter will be initated by de DP-switch (∆P > 0.5 Bar)
●After approx. 10 seconds a flushing cycle needs to be started (Pre-Dwell time)
●If applicable, first close the mainvalve installed after the filter. The flushing cycle may start if the mainvalve is
fully closed. The time needed for the closure is depending on the type of valve installed.
●The flush cycle will be started when both the eletrical motor and the solenoid on the flushing valve are
activated. A flushing cycle needs to be at least 30 seconds. After this time the electrical motor and the solenoid
valve need to be decativated.
●If more than one filter is installed the pressure difference over all installed filters need to be monitored by means
of one DP-switch. The DP switch need to be installed into the combined in- and outlet line.
●If multiple filters are installed the flushing needs to be preformed one after another. Between the changeover of
the filters a dwell time of 5-10 seconds needs to be taken into account.
●In case an electric valve is installed on the auxilairy filter, we recommend to activate this electrical valve every
30 flushing cycles for approximatly 5-10 seconds.
The flushing of the auxilairy filter may never be done during a regular flushing cycle of the 6Matic filter.

Manual flush mode
●For each installed filter there needs to be a possibility to manualy flush the filter.
●The manual flush cycle needs to be identical to the automatic flushing cycle.
General
●When the system, in which the filter is installed, is not operational, it may not start an automatic flushing cycle.
●Make sure that the filter is flushed based on operational uptime. The manual flush cycle needs to be identical to
the automatic flushing cycle. No matter how the flushing cycle was started the interval to the next cycle will
start to be measured again after each ending of a flushing sequence.
●Connect de DP-switch directly to the IO board of the PLC of computer (without routing through a relay).
Advise
●Generate an alarm if a flushing cycle is repeated directly after another multiple times (for instance 3 times).
●Make sure that the amount of flushing cycles per day are logged. It is recommended to distinguish the various
possiblies that can initiate a flushing cycle
●Make sure the following parameters are changable:
qPre-Dwell time (sec.)
qLength of flushing cycle (sec.)
qDwell time (sec.)
qTime interval for flushing cycle (hrs)
qAmount of filters installed
qMain valve installed (Yes/No)
qMain valve time delay (Sec.)
●Flush the filter before or after a duty cycle. (Clean start and clean stop)
●Use an UDI controller for standalone applications.

5.5 - Auxiliary filter
For the reversing mechanism to run smoothly, a similar pressure on both sides is required. The
pressure is equalized by means of the pressure equalizing bypass. The filter in the bypass serves to
keep the reversing mechanism clean.
The filter can be fitted with a screen filter element or a disc filter element. The screen filter is standard
(24B).
Assembly seen from the rear of the 6Matic:
Position and view side auxiliary filter in dashed line.

Screen filter (standard) Disc filter
Screen filter:
If drainage is to be installed under the manual valve, use a funnel or other means so it will be visible
when the valve is left open.
Automatic flushing of the auxiliary filter:
It is possible to automate the flushing of the auxiliary
filter (24B), if required the maual valve needs to
exchanged by a 3/4”elecltrical valve. Our advise is to
activate this electrical valve after every 30 flushing cycles for
approximatly 5-10 seconds.
Important:
The flushing of the auxilairy filter may never be done during a
regular flushing cycle of the 6Matic filter.
Make sure the manual valve(s) for flushing
the auxiliary filters are easily accessible.
If needed change valve position and/or
combine the flushing lines.
