Description of Filter Operation
Filtering process:
The SAF-3000 is a sophisticated yet easy-to-operate automatic filter, with a self-cleaning mechanism driven by an electric motor.
The SAF-3000 is designed to work with various types of screens in filtration degrees from 10 to 500 micron, and is available in 3", 4"
and 6" inlet/outlet diameter.
The water enters through the inlet pipe into the coarse screen from outside in, and through the fine screen from inside out. The
"filtration cake" accumulates on the fine screen surface and creates head loss to develop.
The coarse screen is designed to protect the cleaning mechanism from large dirt particles. Usually, it does not accumulate large
quantities of suspended solids and is not cleaned automatically.
Self-cleaning process:
The SAF 3000 initiates the self-cleaning process when either the pressure differential across the screen reaches a pre-set value or
the flush timer reaches its preset timed interval.
The fine screen filter element is cleaned by the suction scanner, which rotates in a spiral movement while removing the filtration
cake from the screen, and expels it out through the exhaust valve.
A 2-way (fwd/rev) drive unit that is attached to the scanner by a threaded shaft rotates the scanner and provides the linear
movement.
The exhaust valve is activated for the duration of the cleaning cycle by a 3-way solenoid. During the 20 seconds self-cleaning
process, filtered water continues to flow downstream.
System Operation modes:
The filtration system may be found in one of the following modes:
1. Filtering mode: This is the normal operating status. The flush mode is idle and the power light on the control board is lit.
2. Flush mode: The motor and exhaust valve activate according to the previously described self-cleaning process.
3. Continuous flushing mode: It is possible to activate the self-cleaning mechanism continuously by setting the SW1 switch in the
control board to "CONT." position.
4. Malfunction mode: If the filter malfunctions, the self-cleaning operation stops, the malfunction light on the control board is
turned on and a 24V AC external output is activated.
The filtration system enters a malfunction mode under any of the following conditions:
1st. A continuous signal from the pressure differential switch longer than the PD fault time-out (default value=15 minutes)
indicates that the filter is unable to clean itself.
2nd. The motor Over Load protector was activated, either manually or due to actual over load.
3rd. Limit Switch malfunction - (usually, simultaneous activation of both limit switches).

SAF 3000 07.2019 Page 10 of 25
Initiation of self-cleaning:
The filter initiates the self-cleaning process under any one of the following conditions:
1. PD flush - The Pressure Differential Switch (PDS) closes a free potential contact signal when the pressure differential across the
screen reaches the pre-set value (usually 0.5 bar =7 psi). The control board registers the signal and activates the flushing cycle.
2. Test flush - Manually pressing the "TEST" push button on the control board door activates a single flushing cycle.
3. Timed flush - SW1 must be in the DP/Time position. The T1 timer in the control panel activates the flushing cycles at time
intervals, regardless of the pressure differential. The timer resets after every flushing cycle. The PD flush mode is active in this
mode as well.
4. Continuous flush - SW1 must be in cont position. In this mode the filter flushes continuously. This mode is for use in
extraordinary circumstances and for a limited time. Please consult with the manufacturer regarding the uses of this mode.
Control system:
Two types of control boards are available: PLC Type and Relay Type. See Appendix A or B for details.

SAF 3000 07.2019 Page 11 of 25
Installation
Design recommendations:
Design recommendations:
1. Often, flow increases and pressure drop dramatically during fill-up of a water system. In this case, a pressure-sustaining valve
installed downstream of the filter will ensure the minimum required pressure for the filter and a controlled filling-up of the line.
2. If constant water flow is required even during maintenance, it is recommended that a manual or automatic by-pass be installed.
Isolating valves will be used to isolate each filter unit.
3. In applications where the water quality periodically worsens, it is possible to operate an emergency flush program. In order to do
so, an automatic Down Stream valve must be installed. For details, please consult the manufacturer.
Installation instructions:
1. Install the filter horizontally in a manner that will allow convenient access and enough space to dismantle the filter for
maintenance purposes.
2. Check the direction of flow according to the arrows marked on the filter housing.
3. It is recommended to install a mechanical non-return valve downstream of the filter.
4. The exhaust line (minimum 2” diameter) should be designed so that it creates minimal resistance to flow of 11m3/h (50 USgpm).
5. If the system is designed to operate with working pressure higher than 6 bar (85 psi), it is recommended that a manual throttling
valve be installed on the exhaust line, in order to enable regulation of the flushing flow rate.
6. The user should arrange suitable lighting at the area of the filter to enable good visibility and safe maintenance.
7. The user should arrange suitable platforms and safety barriers to enable easy access to the filter without climbing on pipes and
other equipment.
IMPORTANT !!
Prevent static back-pressure or reverse flow through the filter.
Install a manual or a hydraulic valve downstream of the filter.
Electric wiring
1. Install the control board in a dry and protected place (It is possible to order a special control board for severe out-door
installation).
For single phase or DC power supply, please refer to the electrical drawing inside the control board.
2. Power connection to the control board:
a. Connect a three-phase power source through a semi-automatic switch, or 16 Amp. fuse to the L1 L2 L3 connectors at the
terminal strip in the control board.
b. Ground the control board.
3. Power connection to the motor: Connect the drive unit to the control panel using 4 x 2.5 mm (12 or 14 AWG) wires in flex-
conduct. Use a long enough cable to allow removal of the drive unit and placing it near the filter for maintenance, without having
to disconnect it from the cable. (The installation should meet or exceed local or national electrical codes for "high" voltage).
4. Control wiring: Connect the terminals between the junction box and the control panel using 6 x 1.5 mm (16 AWG) wires in flex-
conduit. The numbers on the terminals in the board correspond with those in the junction box.

SAF 3000 07.2019 Page 12 of 25
Start-up and first operation
1. Make sure all the electric wiring is correct, according to the enclosed drawings.
2. Turn on control power and 24VAC but leave OL protector off. Verify that the limit switches are wired correctly by manually
toggling them. Monitor the appropriate inputs according to the wiring diagram accompanying the control panel. Proceed to
next step only after verifying correct wiring of all limit switches in the system.
3. CHECK ROTATION: The suction scanner shaft should turn clockwise (CW) and move towards the filter housing until it reaches
limit switch "A". If the motor rotates in the opposite direction (CCW), turn off the electricity immediately and change the
direction of the motor rotation by changing between two phases.
4. The motor must stop when the limit switch plate reaches limit switch "A" (opening the NC circuit).
5. Operate a "dry" flushing cycle by pressing on the "TEST" push button. Check that the flushing cycle runs as described in the
“Self-cleaning process” paragraph in this manual.
6. Open the inlet valve to the filter, leaving the outlet valve closed or with an open by-pass valve (This will keep the flow through
the filter to a minimum), and operate a flushing cycle.
7. Check that the exhaust valve opens and all stages of the flushing cycle perform properly. Attend to leakage, if any.
8. Close the 1/4" valve at the low pressure sensing port of the pressure differential switch for 5 seconds. The PDS hand will move
to the red area and the filter will start the flushing process. Re-open the 1/4" valve.
9. Gradually open the outlet valve and/or close the by-pass valve. Operate the filter under the designed hydraulic conditions.
10. Set the flushing interval timer (T1) for 6-8 hours.
11. Check and re-tighten all bolts after the first week of operation.
* When using Control board type "C" (Relay type) it is necessary to press the "Test" push button in order to start the motor operation
for the first time.
