properly follow the indications in this manual throughout the life of the product. We invite you
to visit our website: www.itmfilters.com for more information about our products and our
company policies.
1.1 Filter identification
The filter is identified with the following nameplate:
1.2 Basic concepts
Filtration surface: Area that allows water to pass while retaining suspended particles.
Recommended flow: Optimal filtration must take into account the quality of the source water
and its use. The quality of the source water is divided into 4 sections, which have maximum
theoretical flows. The sectorization corresponds to the particles per million in the water.
0. Stretch 1: 0-50ppm.
1. Stretch 2: 50-100ppm
2. Stretch 3: 100/200ppm.
3. Stretch 4: > 200ppm.
Loss of pressure (HEAD LOSS): It is the difference in load produced between two points of the
same flow. The friction of the water with the filter medium produces a loss of energy. The
substances are trapped in the mesh generating a decrease in the porosity of the filter medium,
which causes an increase in the pressure drop. The pressure drop measurement is carried out
by means of a pressure tap on the inlet manifold and another one on the outlet manifold.

4. INSTALLATION
1. Place the filter on an accessible flat surface and in the correct flow direction.
2. Position the inlet and outlet manifolds, fixing the flanges with their corresponding
gaskets.
3. Check that the drain outlet is directed to the desired area.
4. Check that the unions are tight, turn on the water supply and verify that there is no leak.
5. Filtering. Open the water flow at the recommended flow rate and at a working pressure
between 2.5-10 kg/cm².
6. Cleaning. When the pressure gauge indicates a pressure difference equal to or greater
than 0,3 kg/cm², the automatic filter cleaning will begin, without interrupting the water
filtering process. The cleaning cycle leaves the factory with a duration of 30 seconds, it
must be adjusted during installation as it depends on the working pressure. For the
cleaning to be automatic, the key must be in the “AUTO” position.
* Note: Place a check valve at the outlet of the filter, to avoid reverse flows and internal breaks
in the filter.
5. OPERATION
Mesh filtering consists of the physical separation between water and the substances that are
suspended in it. Water flows from the inside of the filter cartridge to the outside, causing dirt to
accumulate on the inside of the filter cartridge.
When the mesh filter becomes clogged, it produces a pressure difference between the inlet and
outlet manifolds. The automatic cleaning cycle starts when it reaches a pressure difference of
0.3 kg/cm². To check that the cleaning cycle is correct, it can be started manually by placing the
key in the ''OPEN'' position.
Cleaning process. As soon as a pressure difference of 0,3 is reached or when 12 hours of
operation have elapsed, the programmer sends the cleaning activation signal. The signal is sent
to the solenoid. The solenoid triggers the hydraulic control system, opens the flushing valve, and
communicates the hydraulic cylinder chamber with atmospheric pressure. This has two effects:
7. The water flows through the nozzles arranged in the scanner and it is expelled through
the turbine. As a result, the water carries the dirt off the screen and in turn causes the
scanner to rotate. That is, the mesh is cleaned around the entire circumference of the
cartridge by the pressure difference.
8. The expulsion of the water from the cylinder is carried out in a controlled way thanks to
a hydraulic calibrated orifice. The advance of the scanner and the nozzles is regulated
by this component, so check that the correct calibrated orifice is installed according to
the working pressure of the filter.

USER MANUAL:
HYDRAULIC-200-H-INOX
The joint hydraulic action of the turbine and the hydraulic cylinder guarantees the sweeping of
the nozzles throughout the filter cartridge.
The pressure difference that occurs between the cleaning chamber (chamber where the turbine
is located) and the filtration chamber must not exceed 2,5 kg/cm². This pressure difference is
read during the cleaning process, by subtracting between the two filter pressure gauges.
A higher pressure difference can lead to deterioration of the filter cartridge. To regulate the
pressure difference, the cleaning valve must be adjusted.
The technology used in the manufacture of the HYDRAULIC-200-H-INOX filter offers high
filtration surfaces with compact lengths, due to the maximization of the filter cartridge.
6. MAINTENANCE AND SPARE PARTS
6.1 Maintenance
Gasket check.
Battery check (if applicable).
The filter mesh requires periodic manual cleaning, for this:
1. Disconnect the power supply and the water supply.
2. Open the drain cock in the “CLOSE” position and wait for the filter to drain.
3. Loosen the screws on the cover of the filtered water outlet area.
4. Remove the filter cartridge and clean it with water on the outside and a cedar brush
on the inside.
5. Insert the mesh cartridge and close the lid making sure it is tight.
On our website: www.itmfilters.com you can find a video tutorial with the maintenance process.

NOTE: All our filters have the control panel configurated according to standard specifications.
7.1 Features listing
The “FILTRON 1-10” is a modular type backwash controller for automatic filters from 1
to 10 stations.
Models for direct current (DC) and alternating current (AC) are available.
The DC model can be powered by either 6v DC or 12v DC and activates 12v DC 2-wire
latch-type solenoids. The voltage for solenoid switching is supplied by a charge pump.
The AC model contains an internal transformer that can be powered by 110V or 220V
from which 24v AC is generated for the solenoids.
The wash cycles can be triggered either by time or by means of the electronic PD sensor
when it reaches the preset value, or by a dry contact signal from an external type PD
sensor.
Looping problems can be eliminated by detecting repeated consecutive cycles that
exceed the predefined value.
The unit can optionally handle a Pressure Sustaining valve, and an Alarm output.
The unit is equipped with a custom LCD screen and keypad.
The unit counts separately the number of washing cycles triggered by DP, by time or
manually.

7.2 How to program the controller
The controller is equipped with an LCD display and 4 keys as shown below. When the unit is not
touched for one minute the display turns off and the only sign of life is given by a beep sound
that can be heard every 20 seconds. Pressing any of the keys for a few seconds will bring the
display back on.
The screen contains several fields, some of them are editable and some of them are not. To
insert the EDIT MODE, press the ENTER key. The EDIT MODE is indicated by the flashing of the
characters in the corresponding editable field. Each time the ENTER key is pressed the next
editable field will come into focus and begin to flash. In EDIT MODE the "+" and "-" keys are used
to change the value of the field under focus. If the ENTER key is pressed again the selected value
will be fixed and the focus will move to the next editable field which will begin to flash. Once
this key editing mode is entered, the user will not be able to go back and must keep pressing the
ENTER key repeatedly, to go through the chain of editable fields until reaching the WASH TIME
field again.
* Please note that before the first use of the unit, it may be necessary to go through the
configuration process before defining the wash program in order to adjust the characteristics of
the controller for a specific use. The setup process is described below.

7.4 Wash time
Defines the duration of the wash time per station. The following options can be selected:
5-20 seconds in 1 second intervals
20-55 seconds in 5-second intervals
1-6 minutes in 0,5 minute intervals
7.5 DP preset value
In this field the user defines the value of the pressure difference between the inlet and outlet of
the filter that, when reached, will cause the beginning of the wash cycle. This field appears only
when the system includes the electronic DP sensor.
When pressure is expressed in BAR, the range of values is 0.1 - 2.0 BAR. When pressure is
expressed in PSI the range of values is 1-30 PSI.
When the system does not include the electronic PD sensor. but an external PD sensor is
connected, the flush request signal comes in the form of dry contact.
7.6 Wash mode
The wash mode defines how the wash cycles will be triggered. The options are as follows:
●OFF - There will be no washing
●By time - In this case the wash cycles will be repeated at a selected interval or triggered
by the DP signal depending on which occurs first. No matter how the wash cycle started,
the interval to the next cycle will start to be measured again after each end of the wash
sequence. The selection ranges are as follows:
-5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 minutes
-2, 3, 4, 5, 6, 8, 12, 18, 24, 72, 120 hours
●DP - the wash will be triggered by DP only.
-5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 minutes
-2, 3, 4, 5, 6, 8, 12, 18, 24, 72, 120 hours
●DP - the wash will be triggered by DP only.
* If the "+" and "-" keys are pressed and held simultaneously, the "Wash Mode" field will show
the time remaining until the next cycle, alternatively, first hours and then minutes.
7.7 Accumulations
The unit accumulates and displays the number of wash cycles caused by DP, by time, or
manually. In each of the accumulation fields, the "+" or "-" keys can be used to clear the
accumulated value.

7.8 Setup
In order to enter the configuration process, press and hold the ENTER key for 3 seconds. The
unit will detect how many “plug in” boards (each with 2 outputs) are used in the particular case.
The assignment of the outputs depends on the definitions made during the configuration
process. During the configuration process, the following characteristics are defined:
Main valve -
(Sustaining valve)
Waiting time -
DP delay -
Loop limit -
Alarm -
Delay Valve -
See outputs -
Yes / No. When the answer is “Yes” you can define the Pre delay.
Wait between the opening of the main valve and the opening of
Station No. 1 The selectable delay intervals are as follows:
5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55 seconds
1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6 minutes
The delay between stations - 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55,
60 seconds.
The delay that the DP sensor reading is expected to be stable before
reacting - 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 seconds.
The number of consecutive wash cycles triggered by the DP sensor
before deciding that there is a no-end-of-loop problem. The options
are: 1-10 or "no" which means to ignore the loop problem.
Yes / No - assigning an output for alarm activation.
Yes / No - assigning an output for Delay Valve activation.
This is a special mode that allows you to review the list of outputs to
see how each of the outputs is assigned. Use the + key to change the
“no” to a “yes” and confirm with “Enter”, then use the + key to scroll
through the list. The output number is displayed in the lower left
corner and its assigned role appears in large letters in the center of
the screen. Note that the number of possible outputs that can be used
is always an even number since it results from the number of plug-in
boards included (2 outputs each). However, if the number of outputs
required is not an even number, then the last valve assigned as a filter
can be canceled by using the manual operations key.
Pressure units -
To choose the units to be used for pressure measurement. Select
between BAR or PSI.
Calibration -
Zero calibration of the integrated electronic DP sensor. If the sensor
ports are disconnected select Calibration = Yes.
Version -
The last screen in configuration indicates the version of the controller
software. The version is displayed with four digits like the following:

7.9 Handling endless loop problems
As explained above, an endless loop problem will be declared when the number of consecutive
wash cycles triggered by the DP sensor exceeds the “Loop Limit” defined during setup. When an
endless loop problem is detected, it will be indicated on the screen (LOOPING) and the alarm
output will be activated. In addition, the indication of DP should no longer be taken into account
as a trigger for washing. Subsequent wash cycles will only be triggered by a countdown interval.
The problem will be considered solved when the constant indication of the DP sensor has been
eliminated.
7.10 Handling low pressure
When an indication of closed contact is received at the controller's low pressure input, the
symbol will begin to appear flashing on the display. All activities will stop including the
countdown to the next wash cycle. If there is low pressure while a flush sequence is in progress,
when the low pressure condition ends, the flush sequence will start from the beginning instead
of continuing from the stop point.
7.11 Connecting the DP sensor to the filter system
The DP sensor is connected to the filter system by 2 command
tubes, one that comes from the filter inlet (high pressure) will be
connected to the red point, and the one that comes from the outlet
(low pressure will go towards the black point. It is important to
install a small 120 mesh filter (not provided) between the red dot
and the high pressure connection point.
7.12 Low battery
The unit has two levels of low battery indication. The first level is when the battery voltage drops
to the first level, the sign will start to appear on the screen. When the battery voltage
continues to drop and reaches the second level, all outputs will close, the screen will clear
displaying only the low battery icon.
7.13 Manual activation
The wash sequence can be activated manually by using the “MANUAL” key. When activated
manually, the icon will appear on the screen. The same key will be used to manually end the
sequence in progress.
The small filter to be added between the high pressure inlet
and the red dot. It is the user's responsibility to add thisfilter
