Self-Cleaning Cycle
The automatic flushing cycle described below takes a few 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.
This 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. The water
and particles passing through the hydraulic rotor cause the dirt collector to rotate, and the piston moves in an axial
direction to the opposite end of the filter.
The combination of rotational and axial movement of the dirt collector assembly ensures that the nozzles sweep the
entire inner surface of the fine screen.
When the first stroke is completed, the flushing valve closes and after a very short interval, the controller activates the
second back flush stroke. The dirt collector assembly spins, moving with the piston in the opposite direction and
returning to its original position.
This self-cleaning process takes between 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 situation, 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 30psi (2bar) 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 to prevent backflow damage to
the screen.
It is recommended to install a pressure gauge on the three-way valve.
Check that there is sufficient space to remove the lid 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.
Allow a convenient approach and enough space for dismantling and maintenance.
Installation Procedure
Ensure the direction of flow is according to the arrows marked on the filter housing.
1. Connect a minimum of 3" (75 mm) pipe to the exhaust valve. The exhaust pipe should be designed so that it creates
minimal resistance to flow of 20m3/h (88 US-gpm). Water should be allowed to flow to atmosphere freely from the
exhaust pipe.
2. Connect a minimum of 1" (25mm) flexible tube to the rinse controller drain port. Ensure this drain line is open to
atmosphere.
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 flushing mode automatically, without prior warning.

M104LPN, M106LP Electronically Controlled 910101-000484 / 12.2019 Page 12 of 31
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.
The nominal diameter of the drainpipe should be at least 3" (75mm).
If the recommended upstream and downstream isolation valves have been installed, check that they are shut.
Getting Started
First operation of the 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 filter's published maximum flow rate.
7. Start a manual flush by pressing the push button on the controller panel.
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.
