Trouble shooting for all models
•Head loss is not decreasing after flushing cycle:
oCheck that the pressure is not below 2 bar.
oCheck that there is no disturbance to the flushing flow.
oFlush the internal screen by opening its valve 1/2".
oRepeat the flushing cycle again, do not forget to open the filter valve 2" before turning the handle.
•Filter is still not clean:
oClean the internal screen: see Periodic Maintenance –Secondary flush
port cleaning (outlined below)
oClean discs manually: see Periodic Maintenance –Discs manual
cleaning (outlined below)
•Filter handle is not turning
oCheck that the bottom valve 2" is fully open before turning the handle.
oCheck that water flows through the bottom valve 2".
oCheck that inlet pressure is lower than 6 bars
•Filter handle is still not turning
oPartly close the inlet maintenance valve and turn the handle
oPerform a flushing cycle, do not forget to open the filter valve 2" before turning the handle.
oOpen the inlet maintenance valve

TDS - Proper flushing of discs
It is recommended to clean the discs before and after irrigation season to ensure proper functioning of the filter
for many years. Manual flushing is required when the filter is clogged and flushing process does not clean it
properly.
•Before opening the filter cup close the inlet valve of the system and release the pressure in the filter battery
by opening the drain valve.
•Release the disc cap and when the discs are loose on the spine perform a manual flushing using a water
hose to flush the discs in high pressure directing the flow tangentially to the spine.
Never open the filter under pressure
•Dismentle discs from the spine.
•Visually check for twisted or worn out discs and replace if required.
•In case of chemical deposits on discs grooves, tie each disc set with a nylon rope and soak the discs into an
appropriate solution –see below. After treatment, rinse thoroughly with fresh water.
•Reassemble the discs on the spines and back in the filter, then close and tighten filter body. Ensure head
loss does not exceed 2-3m.
Detailed explanation of chemical treatment of the discs
Several types of deposits can clog the disc. These can be:
•Organic matter, it will be brown or green and will look like mocus.
•Metal oxide - iron in rust color or managanese in black color.
•Carbonaes - white or grey in color
•Combination of several deposits.
Perform cleaning in a properly ventilated area and use gloves, safety glasses and
protective clothes.
6.1 Preparing the solution for immersing the discs
For organic material use Sodium Hypoclorite
•Mix 5 liters of Hypoclorite (10% concentration) with 5 liters of water. The solution is 5% concentrated.
•Tie the discs with a rope and soak in the solution for 8 hours- then rinse with water thoroughly.
•After installing the discs back in the filter perform several flushing cycles.
For carbonate and iron deposits use Hydroclorite Acid.
•Mix 2 liters of Hypoclorite (30% concentration) with 10 liters of water. The solution is 5% concentrated.
•Tie the discs with a rope and soak in the solution for 8 hours- then rinse with water thoroughly.
For complex deposits
•In case the user is not sure about the type of the deposits he should run a test.
•Put several discs in Sodium ypocloride solution and seveal in a Hydroclorite Acid solution, (prepare the
solution as explained above).
•If one of the dolutions cleans the discs perform cleaning process in that solution.
•If none of the solutions cleaned the discs completely replace the discs that were immersed in the
Hypocloride acid into the Sodium Hypocloride and vise versa and watch which treatment cleaned the discs.
This is the process to follow with all discs.
•If none of the treatments cleaned the discs properly send several discs to a laboratory to get a diagnosis of
th edeposits and the proprer treatment needed in order to clean them.
