backwash valves into the Spin Klin filters.
The water then passes through the filter elements to the outlet manifold for consumer use.
Description of the Backwashing Process
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 backwash valve, moving it from the
filtration mode to the backwash mode.
3. Filter #1 is then backwashed with water from the outlet manifold that has been filtered by the
other filters in the system. Contaminated water and impurities flow out through the drain
manifold.
4. On completion of the allotted backwashing time, the controller releases the backwash command,
and filter #1 returns to the filtration mode.
5. Filter #2 then enters the backwash mode, and the process is repeated until all the filters in the
system have been backwashed.
6. After all the filters have been backwashed the system returns to the filtration mode, until the next
backwash cycle.

Spin Klin Technology - Spin Klin Spine
General:
The Spin Klin discs are stacked on the Spin Klin spine.
The discs are color-coded by micron size,and are assembled
according to your water filtration requirements. The spine
assembly has a spring compression unit and an internal piston
which are used to alternately compress and release the discs
during filtration and backwash cycles.
Filtration Mode:
During the filtration process the filter discs are tightly
compressed together by the spring and the differential
pressure, forcing the water to flow through the grooves and
traps of the discs.
Backwash Mode:
During backwash the discs are released by releasing the inlet
hydraulic pressure. Multi-jet nozzles provide tangential spray
on the loosened discs, causing them to spin, and release the
retained solids, which are flushed out to the drain.
´[´%DFNZDVK9DOYH
Filtration Position:
Water flows from port A (main supply) to port B (filter connection). Port C (drain water outlet) is closed
by the seal.
Backwash Position:
Command pressure is applied to the top side of the diaphragm through port D. The diaphragm moves
down, pushing the sealed body by the shaft. Port A is closed by the seal, preventing flow to the filter.
Port C is now open allowing flushing water to flow from port B (filter connection) to the drain.

Installation
A. Make sure that the inlet and outlet orientation is correct (shown by arrows on filter).
B. Prior to start-up check for any transport damage to the unit (system operates under pressure!).
C. Connect backwash drainage line.
D. Cover clamps need to be properly closed.
Start-up Operation
Start the backwash cycle, making sure that all system components function correctly.
Filter Load-up during Start-up
Close the downstream (flow control) valve (if available).
Flush until clean with repeated cycles.
Slowly reopen the downstream valve.
If the pressure difference remains high, check and see if the flow rate is too high.
An excessive flow rate through the filter causes excessive pressure loss.

Spin Klin ±System Maintenance
Monthly Maintenance
Check inlet /outlet pressures:
In case the pressure differential is above 5 m / 7 PSI.
Activate automatic backwash of the Spin Klin filter battery.
In the event that the pressure differential remains high check for possible failures.
Check for leakages from the drain manifold:
In case there is a leakage of water during the filtration stage, check for possible failure at the
backwash valve seals.
Backwash controller performance:
Check that the controller timing parameters are correctly adjusted and activate automatic
backwash cycle. In the event of possible failure at the backwash controller, check for
possible failures.
Cleaning of the Command Filter:
Close the command filter inlet valve, release the pressure trapped at the command filter,
remove the cover. Thoroughly clean the filtration element and then reinstall the command
filter element and cover, thenopen the inlet valve.
Winterization:
In order 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 open.

Seasonal Maintenance ±Cleaning the Discs
When manual cleaning of the discs is required, please follow the steps described below:
Make sure that system is not under
pressure! Release the clamp and
remove the cover (Figures 1, 2)
Unscrew the butterfly-nut on the filtration
element (Figure 3)
Remove the tightening cylinder
(Figure 4)
Remove the discs (for convenience
we recommend using a plastic bag)
(Figures 5, 6)
Tie each set on a string and place
them in a cleaning solutions (HCL,
Chlorine, or other) refer to ³Cleaning
Recommendations Clogged Filtration

Thoroughly wash the discs with fresh
water (Figure 7)
Reassemble the discs on the spines,
check that the correct quantities of
discs are assembled on the spine:
when the discs are pressed with two
hands, the top disc should be level
with the imprinted circle on the
outside of the spine (Figure 8)
Put on the tightening cylinder and
tighten the butterfly-nut, then
reassemble the filter cover and
tighten the clamp (Figures 9, 10)

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 liter) 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

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 of time as the cleaning activity of the solution deteriorates.
10
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 2½cups (= 500ml) of water into a small container, then add carefully
½cup (= 100ml) of Hydrochloric Acid (30% HCl).
Keep one disc as a control.
Observe the cleaning process:
- If one of the solutions removes all of 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 round.
Check the cleaning process:
- If one of the treatments removes all of the deposit, clean all of the discs following
the same two-step procedure in the exact same order. Rinse the discs well
between the two cleaning processes.
