Introduction
The Electronically Controlled FILTOMAT M100 is a sophisticated, yet easy-to-operate automatic filter, with a self-
cleaning mechanism driven by a hydraulic turbine and controlled by Amiad’s Electronic controller. The FILTOMAT M100
is designed to work with various types of screens with filtration degrees from 500 to 80 micron, and is available in 2"
and 3" inlet/outlet diameter.
The FILTOMAT M100 filters are configured to meet your specific needs according to flow rates and water quality. These
filters can be installed as stand-alone units for low flow rates, or assembled in a group on a manifold when high flow
rates and/or a large screen area are required. The filters are delivered fully assembled, requiring a simple connection to
the inlet and outlet and to the exhaust.
General Description
Water enters the filter through the inlet pipe and passes through a coarse screen which is designed to protect the
cleaning mechanism from large dirt particles. It should not accumulate large quantities of suspended solids and is not
cleaned automatically. The water then flows through a fine screen that filters out the smaller particles. Clean water
then flows from the filter through the outlet. The particles form a "filtration cake" which accumulates on the fine screen
surface. The cake build-up increases the pressure differential across the fine screen, and at a pre-set value of 0.5bar
(7psi) the electronic controller starts the automatic self-cleaning cycle. Suction nozzles sweep across the surface of the
fine screen pulling debris off and expelling it out of the exhaust valve.
This innovative self-cleaning process, utilizes the backflush technique to effectively remove the dirt particles from the
fine screen, and provide an uninterrupted downstream flow during the self-cleaning cycle.

M102C, M103C Electronically Controlled 910101-000349 / 09.2020 Page 13 of 30
Self-Cleaning Cycle
The automatic self-cleaning cycle described below takes several seconds and does not interrupt the supply of process
water.
Water flows from the inlet through the coarse and fine screens to the outlet. At a pre-set pressure differential (0.5 bar ;
7 psi) the controller activates the piston and opens the flushing valve. The water from the rotor chamber flows out the
drain. The pressure in the rotor chamber drops, releasing a strong flushing stream that flows through the filter.
The drop in pressure and corresponding release of the back-flush stream create suction at the nozzle tips. This effect
actuates spot cleaning directly in front of the openings of each nozzle on the inner surface of the fine screen.
Backflush water flows through the collector pipe, via the rotor to the exhaust valve forcing the dirt collector assembly
to spin. The first back-flush stroke begins when the pressure-drop in the rotor chamber permits the suction scanner
assembly to move upward.
When the first stroke is completed, the exhaust valve closes and after a very short interval the controller activates the
second backflush stroke (downward). The dirt collector assembly moves downward returning to its original position.
The two stroke helical movement of the dirt collector assembly as described ensures that the nozzles sweep the entire
inner surface of the fine screen.
This self-cleaning process takes approx. 8-15 seconds, depending on the operating pressure.

Installation
Read these instructions carefully before installing and operating the filter.
Design Recommendations
If a prolonged pipeline fill time causes a temporary high flow and low pressure condition, it is recommended that
you install a pressure sustaining valve downstream of the filter. The pressure-sustaining valve will ensure a
controlled fill-up of the line.
The upstream pressure source should not drop below 2bar (30psi) during the rinse cycle. If this cannot be ensured,
consult the manufacturer.
If continued water delivery is essential even during "down time" maintenance periods, it is recommended that a
manual or automatic by-pass be installed, and that isolating valves be installed up and downstream of each filter
unit for isolation purposes.
Avoid placing the drainage pipe on a rising slope to minimize backpressure.
Secure the open end of the drain pipe to prevent movement during the rinse cycle.
It is recommended to install a mechanical non-return valve downstream of the filter.
It is recommended to install a pressure gauge on the three-way valve.
Check that there is sufficient space to remove the cover assembly and the screen from the filter for
troubleshooting.
Preparations for Installation
Ensure suitable lighting at the area of the filter to enable good visibility and safe maintenance.
Arrange suitable platforms and safety barriers to enable easy, safe access to the filter.
It is recommended to install a mechanical non-return valve downstream of the filter to prevent backflow damage to
the screen.
Allow a convenient approach and enough space for dismantling and maintenance.
Installation Procedure
Ensure the direction of flow according to the arrows marked on the filter housing.
Connect a minimum of 2" (50mm) pipe to the exhaust valve. The exhaust pipe should be designed so that it creates
minimal resistance to flow of 20m3/h (88USgpm). Water should be allowed to flow to atmosphere freely from the
exhaust pipe.
IMPORTANT!!
Prevent static back pressure or reverse flow through the filter.
Install a manual or a hydraulic valve downstream of the filter.
NOTE: The filter may enter flush mode automatically, without prior warning.

M102C, M103C Electronically Controlled 910101-000349 / 09.2020 Page 15 of 30
Preparations
Before using the filter for the first time, go through the following check-list carefully. No special training is required to
carry out these activities.
Check that the upstream pressure at the filter inlet is more than 2bar (30psi) during the rinse cycle.
Check that the filter is mounted in the correct flow direction.
Check that all the control tubes are connected properly and that all connections are tight.
Check that the three-way mini-valve is turned to the automatic position. The arrow on the knob should point to
AUTO, and the sticker on the filter.
The nominal diameter of the drainpipe should be 2" (50mm), in order not to restrict the drain line.
Shut the upstream and downstream isolation valves.
Check that there is sufficient space to remove the cover assembly and the screen from the filter for
troubleshooting.
Getting Started
First operation of filter
After completing the preparation check-list above, perform the following steps:
1. Slowly open the isolating valve at the filter inlet. Water will flow into the filter.
2. Check for leaks and repair if necessary.
3. Check that the minimum inlet pressure remains 2bar (30psi) or higher.
4. Slowly open the isolating valve at the outlet of the filter.
5. If there is a by-pass valve, close it slowly.
6. Ensure the flow through the filter does not exceed the filters published maximum flow rate.
7. Start a manual flush cycle (as described in the controller’s user manual later in this document.
8. During the self-cleaning cycle, check the pressure at the filter inlet and in the rotor chamber.
NOTE: The minimum pressure in the rotor chamber should be 1.5bar (22psi) lower than the inlet pressure.
