Description of Filter Operation
Filtering process:
The SAF-6000 is a sophisticated yet easy-to-operate automatic filter, with a self-cleaning mechanism driven by an electric motor. The
SAF-6000 is designed to work with various types of screens in filtration degrees from 10 to 500 micron, and is available in 6", 8" and 10"
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-6000 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.

SAF 6000 910101-000107 07.2019 Page 10 of 28
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).
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 flush 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 6000 910101-000107 07.2019 Page 11 of 28
Installation
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 11 m3/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 by means of a cable of 4 x 1.5mm2 for a distance of up to
5m. For distance of up to 10m a cable of 4 x 2.5mm2 should be used.
Use a long enough cable to allow the drive unit to be removed and placed near the filter for maintenance, without having to
disconnect it from the cable. (It is recommended that this installation meets or exceeds local or national electrical codes, this is a
"high" voltage connection).
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 6000 910101-000107 07.2019 Page 12 of 28
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.

Troubleshooting
Before beginning any troubleshooting, carefully read the safety instructions chapter of this document and make sure that all the workers at the
filtration site are fully aware of and comply with these and any other local safety instructions.
The filtration system may enter a malfunction mode in the following cases:
Symptom
Remarks and Actions
Fault due to continuous signal from the
pressure differential switch for duration of
more than 15 minutes.
The fault indication lamp is lighted in red
This fault means that the self-cleaning process is not successful.
This fault may be caused by one of the following reasons:
A. The filter is clogged due to heavy dirt load or too high water flow rate.
Close the filter’s downstream valve.
Press the reset button to reset the fault mode. The fault indication lamp
is turned off.
Perform few consecutive manual flush cycles and monitor the PD signal.
Once the filter is clean gradually open the downstream valve and
monitor the PD and the flow-rate. Make sure that the filter doesn’t
exceed its designated flow-rate.
B. The PD switch is faulty.
Ask your qualified electrician to check the PD connections and operation.
Replace the switch if found faulty.
The motor protector was activated
The fault indication lamp is blinking in red
This fault means that the motor was operated under too high load
Note: All the following checks and actions should be done by a qualified electrician
only.
A. Check the motor power consumption when not loaded.
B. Check the limit switches for correct operation and verify that each one of
them stop the motor at its designated point.
C. Verify 3 phase 380VAC power supply to the control board and the motor.
D. Disconnect the drive unit from the suction scanner shaft and verify free
turning of the suction scanner.
Note: If during this fault a request for flushing is received (Manual, Time or DP) the
blinking lamp switches to constant red.
Malfunctioning limit switches
The fault indication lamp is blinking in red
Faulty limit switch may not stop the motor at the right point and therefore the motor
protection may be activated.
Receiving signal from both limit switches at the same time causes fault
A. Check that the limit switches are not mechanically stuck.
B. Ask your qualified electrician to check the wiring and the functionality of the
limit switched.
Note: If during this fault a request for flushing is received (Manual, Time or DP) the
blinking lamp switches to constant red.
The fault indication lamp is blinking in red
after the reset button is pressed
This means that the mechanical/electrical fault still exists. (Overload or Limit
Switches faults)
