4. DESCRIPTION & OPERATION
Disc Filtration Technology
Amiad Water Systems uses a specially designed disc filtration technology. Thin, color-coded polypropylene/ nylon discs are diagonally grooved on both sides to a specific micron size. A series of these discs are then stacked and compressed on a specially designed spine. When stacked, the groove on top runs opposite to the groove below, creating a filtration element with a statistically significant series of valleys and traps for solids. The stack is enclosed in corrosion and pressure resistant housing. During the filtration process, the filtration discs are tightly compressed together by a spring power and differential pressure, thus providing high filtration efficiency. Filtration occurs while water is percolation from the outer diameter to the inner diameter of the element. Depending on the micron rating, there are from 18 (in 400 micron discs) to 32 (in 20 micron discs) stopping points in each track, thus creating the unique in-depth filtration.

Spin KlinTM Technology
Spin Klin Spine – The Core of the Spin Klin Filtration System
The Spin Klin® discs are stacked on the Spin Klin® spine. The discs are color- coded according to micron size and are assembled to suit the water filtration requirements. The spine assembly has a spring compression unit and an internal piston, which operate during alternate filtration or back-flush modes. Inside the housing the spring and the pressure difference compress the discs tightly during the filtration process, forcing the water to flow between the grooves and trap the solids.

IN OUT

Spin KlinTM Automatic Back-flush Operation

Activated by an external command (differential pressure or time) alternate units of the Spin Klin system go into back-flush mode. The inlet three-way valve closes the inlet to the filter pod and opens the drain. The outlet three-way valve closes the outlet of the filter pod and opens the external source. During the back-flush process, the compression spring is released and the pressure difference is eliminated. The spine piston rises, releasing the pressure on the discs. Tangential jets of clean water are pumped at high pressure in the opposite direction through nozzles at the center of the spine. The discs spin free and clear, loosening the trapped solids. Solids are quickly and efficiently flushed out through the drain.

5. DESCRIPTION AND FILTER OPERATION
During the filtration stage, water flows through the INLET manifold and is distributed through the first 3″x3″ back-flush valves into the Spin Klin filters. The water then passes through the filters’ elements to the outlet manifold through the second 3″x3″ backflush valves for consumer use.
Description of the Back-Flushing Process
The back-flushing process of this system is carried out by external source water; therefore each filter is equipped with 2 flush valves.
1. The controller transmits an electrical command to the first solenoid according to either differential pressure or time.
2. The solenoid then sends a pressure command to the back-flush valves, switching them from filtration mode to back-flushing mode.
3. Filter #1 is then back-flushed with water from the External Water Source. Contaminated water and impurities flow out through the drain manifold.
4. Upon completion of the allotted back-flush time the controller releases the back-flush command. Filter #1 returns to filtration mode.
5. Filter #2 then enters back-flushing mode and the process is repeated until all the filters in the system are back-flushed.
6. After all the filters have been back-flushed the system returns to filtration mode, till the next backflush cycle.

7. INSTALLATION AND OPERATION
Installation
A. Check for any transport damage (the system operates under pressure!). B. Make sure that the inlet and outlet flow orientations are correct (shown by arrows on the system). C. Connect the Inlet the Outlet and the Drain ports together with their valves to the Main Manifolds. D. Verify that all the covers’ clamps are properly closed! E. Connect and check the water source pressure. F. Connect the Air pressure source to the solenoid and Accumulator.
Start-up Operation
· If possible, perform a dry test run (once or more) on the system and make sure that all the connections and wiring are ok.
· Run the system by slowly opening the inlet valve; allow air to vent out of the system through the Air Release Valve which is mounted on top of the Inlet manifold.
· Once the air is vented, check for any leakage that may happen during transportation and installation. · If the pressure difference across the filters is high, verify that the flow rate is not too high. An excessive flow
rate through the filter causes excessive pressure loss. · Open the Air Supply and check the air pressure. · Manually start a back-flushing cycle and make sure that all the system’s components function correctly. · If after the back- flushing cycle the pressure difference is not reduced, check that the flow is not too high.
PLC/Control
Note: PLC/Controllers are varied according to the Order.
· Refer to the manufacturer’s handbook before installing the PLC/Controller. · Make sure that the voltage is correct BEFORE connecting it. · Check that the P hydraulic switch HIGH and LOW pressure tubes are correctly connected to the appropriate
ports. · Set the DP Switch to the required P (Recommended P is 5m/ 7PSI according to the site conditions). · Set the PLC/Controller Back-flush Time to 15 seconds and the Dwell time to 5-10 seconds. These settings may
require adjustment in order to conform to local water conditions. Typically, a 1 to 3 hour interval between back-flushing cycles is recommended. · Typically, the Back-flush Cycle Time is used as a backup for the DP switch; any signal that triggers a backflushing cycle resets the back-flush cycle timer (including Manual Start command).

Start-up Operation
A. Gradually open the inlet valve (make sure that the outlet valve is partially open).
WARNING Take precaution while operating the system as it may enter to back- flush mode automatically, without warning.
B. Check the system assembly and its connections for leaks.
C. Perform a back-flush cycle by disconnecting the low-pressure tube from the differential pressure indicator (closing the electrical circuit) make sure to re-connect it immediately as the back-flush cycle starts.
D. Verify that the back-pressure reading during back-flushing is according the recommended pressure for your system specific filtration degree.
E. When the filter is clean, verify that the differential pressure between the inlet and the outlet ports does not exceed 2m (3 PSI).
F. Check that the differential pressure indicator is set for starting a back- flushing cycle at 5m (7 psi)
G. Perform an additional back-flushing cycle manually by rotating the operation handle (turn clockwise 90) located on the solenoid valve. Make sure to rotate the handle back to automatic mode once the backflushing starts.

8. SPIN KLIN SYSTEM MAINTENANCE
Monthly Maintenance
Check the inlet /outlet pressures: When the pressure differential is above 5m / 7 PSI, activate automatic back-flush of the Spin Klin system. In the event that the pressure differential remains high, check for possible failures.
Check for leakages from the drain manifold: When there is a leakage of water to the drain during the filtration stage, check for possible failure of the backflush valve seals.
Back-flush controller performance: Check that the controller timing parameters are correctly adjusted and activate the automatic back-flush cycle. In the event of a back-flush controller malfunction, check for possible failures.
Cleaning of the Command Filter: Close the command-filter inlet valve, release the pressure trapped in it and remove the cover. Thoroughly clean the filtration element, then reinstall the command filter element and cover and open the inlet valve.
Winterization: To prevent the filter battery becoming damaged during water freezing ­ drain all the water from the filter battery and the command filter and leave the drain valve opened.
NOTE: Before performing any maintenance work on the battery, make sure all water and air connections are disconnected and that the pressure has been released.

Cleaning Recommendations for Clogged Filtration Discs
Water-formed deposits may cause clogging of the filter discs. The formation of these deposits depends on the quality of the filtered water and environmental conditions like temperature, pH, light, duration of filtration and more.
Common water-formed deposits are:
· Biological or organic deposits (mostly mucous or oily to the touch, beige, brown or green in color) · Iron oxide (rust) or other metal oxides · Carbonates (white or gray deposit) · Combinations of the above If these deposits cannot be eliminated by pretreatment of the water, we recommend the following cleaning procedure:
Material and Equipment
· A well ventilated working place. · 2 small containers (1 liter), 2 large containers (15 liters) and a stirring stick, all resistant to chemicals,
preferably of polypropylene. · Plastic rope to tie up the disc. · Sodium Hypochlorite NaOCl – Strong oxidizing liquid, commercial concentration: 10%. Oxidizes and
removes organic and biological deposits. · Hydrochloric Acid HCl – Very corrosive liquid, commercial concentration: 30%. Dissolves and removes
carbonates, iron oxide, and other deposits. · Safety equipment: safety glasses, gloves, long pants, long sleeved shirt and shoes.
ATTENTION!
While working with chemicals protect yourself with the necessary safety equipment:
· Safety glasses, gloves, protective clothing · Work in a well-ventilated area · Follow the manufacturer’s instructions
Cleaning Organic and Biological Deposits
· Open the filter and remove dirty discs. Attention ­ Never open the filter before the pressure has been released.
· Arrange the discs loosely on the plastic rope · Prepare a 5% Sodium Hypochlorite solution:
1. Pour 5 liters of water into one of the large containers. 2. Add 5 liters of Sodium Hypochlorite (10%) into the water. · Soak the discs in the solution so that both sides are covered. To achieve maximum cleaning, agitate the discs several times with a stirring stick. · Contact time with cleaning solution: up to 8 hours · Remove the discs carefully from the solution, put them in the second large container and rinse them very well with clean water before placing them back in the filter. · We recommend flushing the cleaned discs again in the filter to ensure that all chemical residues are removed. The cleaning solution can be used for several sets of discs. As the cleaning activity of the solution deteriorates, it may be necessary to soak the discs for a longer time.

Cleaning Carbonates and Iron Deposits
· Open the filter and remove the dirty discs. · Arrange the discs loosely on the plastic rope. · Prepare a 5% Solution of Hydrochloric Acid:
1. Pour 10 liters of water into one of the large containers. 2. Carefully add 2 liters of Hydrochloric Acid (30%) into the water. Soak the discs in the
solution so that both sides will be covered. PLEASE NOTE: Carbonates react violently with hydrochloric acid (foaming, gas evolution). To achieve maximum cleaning, agitate the discs several times with a stirring stick. · Contact time with cleaning solution: 1 – 8 hours. · Remove the discs carefully from the solution and rinse them well with clean water before placing them back in the filter. · We recommend flushing the cleaned discs again in the filter to ensure that all chemical residues are removed.
The cleaning solution can be used for several sets of discs. It may be necessary to soak the discs for a longer period as the cleaning activity of the solution deteriorates.
Cleaning Complex Deposits
If the composition of the deposit is not known, perform the following test:
· Take 5 discs for the test. · Soak 2 discs in a 5% Sodium Hypochlorite Solution.
Preparation of the solution: Pour 1 cup of water into a small container, then add 1 cup of Sodium Hypochlorite (10% NaOCl). · Soak 2 discs in a 5% Hydrochloric Acid Solution. Preparation of the solution: Pour 2½ cups (= 500ml) of water into a small container, then add carefully ½ cup (= 100ml) of Hydrochloric Acid (30% HCl). · Keep one disc as a control. Observe the cleaning process: If one of the solutions removes all the deposit, clean the discs in that solution according to the instructions above. If neither solution removes the deposit completely, continue with the test procedure. · Remove the discs from both solutions, rinse them well with water and soak them in the second solution: put the two discs, which have been in the Sodium Hypochlorite Solution, in the Hydrochloric Acid Solution, and the other way around. · Check the cleaning process: If one of the treatments removes all the deposit, clean all the discs following the same two-step procedure in the exact same order. Rinse the discs well between the two cleaning processes. If the deposit hasn’t been completely removed, send a set of untreated discs to the laboratory for further examination.

13. AMIAD LIMITED WARRANTY
1. This certificate applies to Amiad Water Systems Ltd. (“Amiad”) products purchased by you (the “Buyer”) from Amiad unless specifically agreed otherwise in writing by Amiad. This Warranty extends only to the original purchaser, and is not transferable to anyone who subsequently purchases, leases, or otherwise obtains the product from the original purchaser.
2. Amiad hereby warrants that the products are and will be free from defects in material and workmanship under normal use and service. Amiad warrants that it will correct manufacturing defects in the products, in accordance with the conditions set out in this Warranty.
3. This Warranty is enforceable for a period of 12 months after the date upon which the products were delivered (the “Warranty Period”).
4. In the event that during the Warranty Period the Buyer discovers a defect in material and/or workmanship in any product or part (the “Defective Product”), it shall submit a written complaint to Amiad using Amiad’s standard Buyer Complaint Form. For the receipt of the Buyer Complaint Form, the submission of the complaint or any questions please contact your service representative.
5. Upon written demand by Amiad the Buyer shall return the Defective Product – or a sample thereof – to Amiad, at Amiad’s cost. If the Buyer ships any such Defective Product, Amiad suggests the Buyer package it securely and insure it for value, as Amiad assumes no liability for any loss or damage occurring during shipment. Provided however that in the event Amiad determines that this Warranty does not apply to such product, Buyer shall promptly reimburse Amiad for such cost (including freight and customs). Any returned product or part must be accompanied by the Warranty certificate and the purchase invoice. It is clarified that the Buyer may not return the Defective Product unless such return was coordinated and approved by Amiad in advance.
6. Amiad’s obligation under this Warranty shall be limited to, at Amiad’s option, the repair or exchange, free of charge, of the product or any part which may prove defective under normal use and service during the Warranty Period. The provision of a repair or replacement of a product during the Warranty Period will result in an extension of the Warranty Period by an additional period of 12 months, provided that the total accumulated Warranty Period shall in any event be no more than 18 months from the date upon which the products were delivered.
7. This Warranty is valid on the condition that the products are installed according to Amiad’s instructions as expressed in Amiad’s instruction manuals and according to the technical limitations as stipulated in Amiad’s literature or as stated by a representative of Amiad.
8. This Warranty will not apply to damaged or defective products resulting from or related to:
(i) Fire, flood, power surges or failures or any other catastrophe and/or unforeseen occurrence, such as but not limited to those for which the Buyer is customarily insured for, or any force majeure events;
(ii) Fault, abuse or negligence of the Buyer; (iii) Intake water not meeting the agreed standards, as set forth in a written document, approved by Amiad, or improper storage; (iv) Improper or unauthorized use of the product or related parts by the Buyer, including Buyer’s failure to operate the product in
conformity with the recommendations and instructions of Amiad, as set forth in Amiad’s manuals and other written materials, the operation of the product other than by a trained and qualified operator, or improper installation of the product by a third party not authorized by Amiad; (v) Performance by the Buyer of maintenance or operation other than in conformity with the recommendations and instructions of Amiad, or other than in accordance with procedures defined in the literature supplied for products (including the timely replacement of requisite parts), and for services provided other than by a trained and qualified advanced operator; or (vi) Any alteration, modification, foreign attachment to or repair of the products, other than by Amiad or its authorized technical representatives.
9. In no event shall Amiad be liable to the Buyer or any third party for any damages to property, or for any intangible or economic loss, including loss of profits, loss of customers or damage to reputation, for any damages, including indirect, special, consequential damages, or punitive damage arising out of or in connection with this Warranty, or arising out of or in connection with the product’s performance or failure to perform, even if it has been advised of the possibility of such damages.
10. Amiad will be excused for failure to perform or for delay in performance hereunder if such failure or delay is due to causes beyond its reasonable control or force majeure preventing or hindering performance.
11. This Warranty set forth herein is the only contractual warranty given by Amiad and is provided in lieu of any other warranties created by any documentation, packaging or otherwise.
12. Amiad makes no warranty whatsoever in respect to accessories or parts not supplied by Amiad. In the event that Amiad is required to correct a Defective Product or product not covered by this Warranty, it will do so solely in consideration for additional fees.
13. The parties will actively endeavor to amicably settle any dispute arising between them. In the event that the parties are unable to reach an equitable settlement of such dispute, any claim or lawsuit related to the Warranty, its validity execution, its performance be brought before only the courts of Tel- Aviv, Israel. Israeli law will govern the Warranty, to the exclusion of any conflict of law rules.
