INTRODUCTION
The FILTOMAT® M100C series filter is a well designed, simple to install and easy-to-operate automatic
water filter. The FILTOMAT will work with a range of fine screen mesh sizes from 50 to 800 micron, to
suit various applications and is available with 2"& 3" BSP female inlet/outlet ports and 4” flanged.
The FILTOMAT filters are selected to meet your specific needs according to flow rates and water quality.
The M102C, M103C & M104C model filters are generally installed as stand-alone units for low flow rates.
For higher flow rates and/or where a larger screen area is required, a range of larger models is also
available. The filters are delivered fully assembled, requiring simple connections to the inlet, outlet and
drain lines. Proper care and maintenance will give many years of trouble free operation.
General Description
Water enters the filter through the inlet pipe and passes through a coarse screen, which protects the
cleaning mechanism from larger particles. It is not designed to accumulate quantities of large suspended
solids as it is not cleaned automatically. The water then flows through a fine screen that filters out the
smaller particles, and the filtered water continues on through the outlet. The smaller particles accumulate
on the fine screen surface and forms a "filter cake", the cake build-up increases the differential pressure
(DP) across the fine screen, and at a pre-set DP point, the automatic self-cleaning cycle is actuated, which
basically consists of nozzles sucking the debris off the screen and expelling it out the drain line.
This innovative self-cleaning process, effectively removes the dirt particles from the fine screen, while still
maintaining flow downstream during the cleaning cycle.
The M100C series Filtomat filters are hydraulically operated, utilizing the system flow and water pressure,
no external power source is required. This method of control enables operation at remote installation sites.
Where electrical power is available, the option of electric control can also be provided with the filter, or
alternatively, where the customer has an existing PLC available with spare capacity, the filter can be fitted
out and supplied, ready for integration with the customer’s PLC.

Operating Principles
The automatic self-cleaning cycle is simple and effective, and takes 5-10 seconds, with only minor
interruption, if any, to the downstream water supply. (this is relative to the water supply/pump
performance available).
Water flows from the inlet through the coarse and fine screens to the outlet. The filter cake builds up on
the fine screen and when it reaches the pre-set differential pressure (DP) of 50kPa, the rinse controller is
actuated and starts the cleaning cycle.
The exhaust valve opens to atmosphere, creating a pressure drop in the rotor chamber, which creates
suction at the nozzle tips, removing the dirt built up on the screen surface.
The backflush water flows through the nozzles to the collector pipe and via the rotor to the exhaust valve
and out through the drain. The escaping water flowing through the rotor forces the dirt collector assembly
to spin, and move up vertically at the same time, subsequently the nozzles are sucking the dirt off the
total screen area. When the first stroke is completed, the exhaust valve closes for a few seconds, and the
rinse controller activates the second backflush stroke (downward). The dirt collector assembly rotates and
moves downward returning to its original position and the exhaust valve shuts.
The two stroke helical movement of the dirt collector assembly as described, ensures that the nozzles
sweep the entire fine screen surface twice per cleaning cycle.
This self-cleaning process takes approximately 10 seconds, depending on the operating pressure.

INSTALLATION Read these instructions carefully before installing and operating the filter.
Design Recommendations
The filter can be mounted vertically or horizontally.
¾For a prolonged high flow and low pressure condition, due to the filling of pipelines on start up, it is
recommended a pressure sustaining valve (PSV) is installed downstream of the filter. The PSV will
ensure backpressure on the filter, and controlled filling of the pipeline.
¾The filter inlet pressure should not drop below 200 kPa during the rinse cycle. If this cannot be
ensured, consult your local dealer or manufacturer’s agent.
¾If water supply is essential at all times, it is recommended that a manual or automatic by-pass be
installed.
¾The drain line should be 50 mm (2”) minimum, and open to atmosphere, to minimise backpressure on
the filter. Avoid running the drain line more than 12 metres or placing it on a rising slope.
¾Secure the drain line to prevent movement/damage during the rinse cycle.
¾Minimise bends and elbows on the drain line. Note: The complete cover lid assembly can be removed
and rotated at 90ºintervals to allow a more direct route to your drain point. The filter drain line outlet,
should not be located near the pump suction inlet.
¾The Rinse Controller has a 1”BSP Fem. (25 mm) drain port on the bottom which bleeds about ½ litre
per backflush cycle. This can also be connected to the main drain line, preferably at an angle to
eliminate any backflow or backpressure.
¾We recommend a mechanical non-return valve be installed downstream of the filter.
¾The pressure gauge supplied, is to be mounted on the three-way valve on the filter.
¾Check that there is sufficient space to remove the cover assembly and the screen from the filter for
servicing and troubleshooting.
Preparations for Installation
¾Provide suitable lighting around the filter area, for good visibility and safe maintenance.
¾Arrange suitable platforms and safety barriers where required, for safe access to the filter.
¾It is recommended a mechanical non-return valve be installed downstream of the filter to prevent
backflow damage to the screen.
¾Allow enough space for dismantling and maintenance of the filter.
Installation Procedure
Ensure the direction of flow is according to the arrows marked on the filter housing.
1. Connect a minimum of 2" (50mm) pipe to the drain. The drain line should be installed so that it creates
minimal resistance to a flow of 20m3/h. Water should flow freely from the drain line to atmosphere.
2. Connect a minimum of 1" (25mm) flexible tube to the rinse controller drain port. Ensure this drain line
is open to atmosphere.
IMPORTANT!!
¾Prevent static backpressure or reverse flow through the filter.
¾Install a manual isolating valve after (downstream) the filter.
¾Install a manual isolating valve before (upstream) the filter if there is any static head on the
inlet side.
¾If the inlet operating pressure falls below 250 kPa install a pressure sustaining valve (PSV)
after the filter.
NOTE: Once pressurized the filter may flush automatically, without prior warning.

COMMISIONING
Before using the filter, go through the following check-list carefully. No special training is required to carry
out these activities.
¾Check that the filter is mounted in the correct flow direction.
¾Check that all the control tubes are connected properly and that all connections are tight.
¾Check that the three-way mini-valve is turned to the automatic position. The arrow on the knob should
point to AUTO, and the red sticker }on the filter.
¾The nominal diameter of the drainpipe should be 2" (50mm), do not restrict the drain line, it should be
open to atmosphere.
¾Shut the upstream and downstream isolation valves.
¾Check that there is sufficient space to remove the cover lid assembly and the screen from the filter for
servicing/troubleshooting.
¾Check that the drain line has a union fitted, to allow removal of the cover lid assembly for servicing.
¾Check that the pressure gauge has been fitted on the brass 3-way valve.
GETTING STARTED
First operation of filter
After completing the preparation check-list above, perform the following steps:
1. Slowly open the inlet valve at the filter, and pressurize the vessel.
2. Check for leaks and repair if necessary.
3. Check that the minimum inlet pressure remains 200 kPa or higher.
4. Start a manual flush by turning the three-way valve to the OPEN position for a few seconds, and then
turn it back to AUTO. You may have to cycle the unit several times to clear the lines of air.
5. Slowly open the outlet valve at the filter. If you are filling the pipeline/s after the filter, throttle this
valve and maintain pressure (above 200 kPa) at the filter, until the lines are full and pressurised.
(unless a pressure sustaining valve is fitted to perform this function.)
6. If there is a by-pass valve, close it slowly.
7. Ensure the flow through the filter does not exceed the filter’s maximum flow rate.
8. Start a manual flush by turning the three-way valve to the OPEN position for a few seconds, and then
turn it back to AUTO. The cycle duration is approx. 5-10 seconds.
9. During the self-cleaning cycle, check the pressure at the filter inlet does not drop below 200 kPa, and
check the pressure in the rotor chamber.
NOTE: The minimum pressure in the rotor chamber should be 150 kPa lower than the inlet pressure.

ADJUSTING THE RINSE CONTROLLER
NOTE: Improper adjusting of the rinse controller may cause the filter
to malfunction.
1. Disconnect the 1”(25mm) rinse controller drain line.
2. Flush the filter manually, using the 3-way valve as per item 8, Page
9 to ensure you start with a clean filter.
3. Loosen the locking nut on the long nose (1) and loosen the
adjusting screw (2), anticlockwise, slowly until a self-cleaning cycle
begins.
4. Turn the adjusting screw (2) clockwise 1.5 turns, and then tighten
the locking nut (1). This adjusts the rinse controller for a
differential pressure of approx. 50 kPa.
5. Observe at least one automatic self-cleaning cycle, if possible,
checking the differential set point with the gauge on the 3–way
valve.

MAINTENANCE
Before shutting down the filter, flush the filter manually via the 3-way valve. By doing this you can
observe the cleaning efficiency of the unit. By checking the inlet/outlet pressure on the gauge.
NOTE: De-pressurize the filter before disassembly or maintenance (close inlet, and then outlet valve),
then manually flush the unit to release the pressure from the vessel, check the pressure gauge to make
sure all pressure has been relieved.
Checking the Filter
1. Remove the filter cover lid assembly by unscrewing the 8 nuts. (Note: a thinner nut is fitted under
the drain line).
2. Extract the fine screen using the screen puller provided,(refer to page 19) and clean if necessary,
the screen is only retained by the o-rings on the outside diameter. Cleaning is best achieved using a
high pressure water cleaner (Gernie), only spray the screen from the inside out !. If there is an
iron oxide or calcium carbonate build up on the mesh, you will need to clean it with a diluted acid
solution (1:10 hydrochloric acid:water). Make sure suitable protective equipment is worn, a 5 minute
soaking and then pressure clean as above. (repeat if necessary). Avoid long periods in the acid
solution, as this will ruin the screen.
3. Check the coarse screen and clean if necessary.
4. Check the O-rings of the fine screen, replace if necessary and apply suitable lubricant.
5. Install the fine screen, pushing it home on the o-rings.
6. Fit the cover lid assembly, carefully aligning the dirt collector shaft into the bearing and fit and
fasten the 8 nuts, fit the thin nut first. Just nipping them up is enough!
7. Perform First Operation of Filter as on page 9.
Decommissioning
If the filter is to be shut down for any period of time, e.g. The end of an irrigation season the following
procedure should be followed:
1. With the pump on, close the outlet isolating valve completely and perform two manual rinses.
2. Turn the pump off.
3. Close the inlet valve if fitted.
4. To restart the system open the inlet valve and do the same as above, then open the downstream
valve slowly with the valve open enough to re-charge the down stream pipework, (not required if a
PSV valve is fitted) maintain at least 200 kPa backpressure on the filter while doing this. Once the
pipeline has been pressurised open the valve fully.
Note: If in doubt, please call us for assistance.
