DESCRIPTION OF FILTER OPERATION
Filtering process:
The SAF-1500 is a sophisticated yet easy-to-operate automatic filter, with a self-cleaning mechanism driven by an electric
motor. The SAF-1500 is designed to work with various types of screens in filtration degrees from 500 to 10 micron, and is
available in 2", 3" and 4" inlet/outlet diameter.
The filter is available in "In-Line" configuration as well as in "Modular" configuration.
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 causes head loss to develop.
The coarse screen 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.
Self-cleaning process:
The SAF 1500will start the self-cleaning process when the pressure differential across the screen reaches a pre-set value or a
predetermined lapse of time.
Cleaning of the filter element is carried out 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.
The rotation of the scanner is operated by a 2-way (fwd/rev) drive unit that is attached to the scanner by a threaded shaft
which provides the linear movement.
The exhaust valve is activated for the duration of the cleaning cycle by a 3-way solenoid. During the self-cleaning process,
which takes approximately 20 seconds, filtered water continues to flow downstream.
Different modes of filtration:
The filtration system may be found in one of the following modes:
1. Filtering mode: This is the normal function condition. Flushing is not occurring and the power light on the control board is lit.
2. Flushing mode: A mode in which the flushing process is in progress. The motor and exhaust valve are operating according to
the program.
3. Continuous flushing mode: It is possible to activate the self-cleaning mechanism continuously by changing the switch near the
timer in the control board to "CONT." position.
4. Malfunction mode: During malfunction mode the self-cleaning operation is stopped, the malfunction light on the control
board is turned on and an external output is activated with 24V AC.

SAF - 1500 910101-000102 07.2109 Page 11 of 26
The filtration system may enter a malfunction mode in the following cases:
1st. When there is a continuous signal from the pressure differential switch for a duration of more than the pre-
set time. This means that the self-cleaning process is not successful.
2nd. When the motor protector was activated, either manually or due to over load.
3rd. As a result of a malfunction in the limit switches.
Initiation of self-cleaning:
The filter will enter the self-cleaning process as a result of any of the following causes:
1. A signal from the Pressure Differential Switch (PDS) - The PDS which is situated on the filter body, sends an electric 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 operates the flushing process according to its program.
2. Manually pressing the "TEST" push button at the control board.
3. The TIMER installed in the control board allows operation of self-cleaning process at time intervals that can be set up,
independent from the head loss factor. The timer resets after every flushing cycle.
4. A signal from Continual flushing switch - This switch in the control board allows operation in continuous flushing mode;
meaning, the filter is flushing itself all the time regardless of flow rate or water quality.
Control system:
Two types of control boards are available: PLC Type and Relay Type. See Appendix A or B for details.

SAF - 1500 910101-000102 07.2109 Page 12 of 26
INSTALLATION
Design recommendations:
1. If flow increases and pressure drops dramatically for a long period of time during network filling-up, it is recommended that
a pressure sustaining valve is installed downstream. The pressure sustaining valve will ensure a controlled filling-up of the
line.
2. If continual water flow is essential even during maintenance period, it is recommended that a manual or automatic by-pass
is installed, and the isolating valves will be used to isolate each filter unit.
3. In places where there is an expected temporary worsening of water quality, it is possible to operate an emergency flushing
program. In order to do so, a hydraulic controlled valve has to be installed downstream. For details, please consult the
manufacturer.
Installation instructions:
1. Install the filter horizontally in a way which will allow convenient approach and enough space to dismantle the filter for
maintenance purposes.
2. Ensure 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. Connect a minimum of 2" pipe to the exhaust valve. The exhaust pipe should be designed so that it creates minimal
resistance to flow of 6 m3/h (26 USgpm).
5. If the system is designed to operate with working pressure higher than 6 bar (85 psi), it is recommended that a manual valve
is installed on the exhaust pipe, 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 4 x 2.5 mm (12 or 14 AWG) wire 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. (It is recommended that this installation meets or exceeds local or national electrical
codes, this is a "high" voltage connection).
4. Control wiring:
Connect between the control junction box and the control board by means of 6 x 1.5 mm 2 (16 AWG) wire in flex-conduct.
The numbers on the terminals in the board and in the junction box are identical.

SAF - 1500 910101-000102 07.2109 Page 13 of 26
Start-up and first operation
1. Make sure all the electric wiring is correct, according to the enclosed drawings.
2. Switch the control & 24V circuit breakers and the motor protector to ON. The motor will start operating *.
1. The suction scanner shaft should turn clockwise and move towards the filter housing until it reaches limit switch "A". If the
motor rotates in the opposite direction, disconnect the electricity immediately and change the direction of the motor
rotation by changing between two phases.
2. The motor must stop when the limit switch plateb reaches limit switch "A" and causes it to operate.
3. Operate a "dry" flushing cycle by pressing on the "TEST" push button. Make sure all flushing stages occur as described in
the filter description chapter of this manual.
4. Open the inlet valve to the filter, while the outlet valve remains closed or with an open by-pass valve (This will keep the
flow in the filter at a minimum), and operate a flushing cycle.
5. Make sure the exhaust valve opens and all stages of the flushing cycle are carried out. Attend to leakage, if any.
6. Close the 1/4" valve at the low pressure point 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. Open the 1/4" valve.
1. Gradually open the outlet valve and/or close the by-pass valve. Operate the filter at the designed hydraulic conditions.
2. Set the timer for 6-8 hours.
7. Check and re-tight 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.

2. Insert the screen into the filter housing (1) while the support legs point upwards. After pushing the screen all the way in,
rotate the screen so that the legs will support it and lead it to its position. Turn the screen round until the locking pin (on
the inner side of the housing wall) is situated in its slot on the centering ring (14).
3. Insert the cylinder seal (12), so that its open side faces the direction of the filter lid.
4. Clean and apply some grease on the suction scanner pipe and on the O-ring (12) of the suction scanner bearing located in
the flushing chamber.
5. Insert the coarse screen (11) in its position, so that it rests on its supports.
6. Insert the flushing chamber (15), make sure the seal is on top of the chamber centering ring with its opening facing the
inner side of the filter housing. The installation should be done at a slight angle and in circular motion.
7. Assemble the lid on the filter housing. Tighten the bolts (19,20) in a controlled and balanced method.
8. Open the filter inlet and outlet valves and operate the control board.
9. Check proper operation of the filter.
Dismantling the suction scanner:
1. Close the inlet valve to the filter, release the pressure and disconnect power supply from the control board.
2. Remove the cover (29) from the drive shaft housing (4) by unscrewing the wing nuts (23.6).
3. Remove the Split pin (10) and pull out the connecting pin (9).
4. Begin the dismantling procedure as per 1-6 in the chapter "dismantling the screens".
5. Pull the suction scanner (8) in a spiral movement out of the filter housing.
Assembly:
1. Apply some grease on the smooth side of the suction scanner shaft (2 p.22) and insert it through the filter housing.
2. Insert the suction scanner shaft (2 p.22) into the drive shaft (2 p.24). Make sure the holes in the above shafts are parallel.
3. Insert the connecting pin (9) to the parallel hole of the suction scanner shaft (2 p.24) and the drive shaft (2 p.22) and lock it
with the split pin (10).
4. Continue to assemble the parts as per 1-9 in the chapter "Assembling the screens".

Dismantling the drive shaft housing:
1. Close the inlet valve to the filter, release the pressure and disconnect power supply from the control board.
2. Dismantle the suction scanner and screens as described previously.
3. Remove the limit switch sling (6 p.24) from the drive shaft housing by unscrewing the bolts. Carefully put the limit switch
sling near the filter to avoid any damage to the electrical wires.
4. Remove the drive unit (22) from the drive shaft housing (4 p.24) by unscrewing the nuts from the bolts. By doing so the
drive shaft key (21) will be pulled out.
5. Dismantle the drive shaft housing (4) from the housing flange by unscrewing the bolts.
Assembly:
1. Verify that the O-ring (3) is clean and in its place.
2. Tighten the flange of the drive shaft housing to the filter with bolts.
3. Insert the suction scanner, the fine screen and the coarse screen as described previously.
4. Connect the drive shaft to the scanner shaft using the connecting pin and split pin.
5. Make sure the drive shaft key (21) is fitted properly in the gear box. Thread the drive shaft through the drive unit and make
sure that the drive shaft groove is adjusted in accordance with the drive shaft key.
6. Connect the drive unit (22) to the drive shaft housing (4) with the bolts and tighten them.
7. Assemble the limit switch sling (6 p.24) in its place. Make sure that the Limit Switch Plateis in the middle of the scanner
travel.
8. Operate the control board and make sure the filter is operating properly.
9. Open the inlet and outlet valves and recheck filter operation.
