Assembly
•Connect the 2” flush valve to the bottom of the filter cup,
(no need to use Teflon, valve is self-seal).
Make sure handle open position is away from filter cup.
•Connect the ½” flush valve to the flush screen outlet, (no
need to use Teflon, valve is self-seal).
•Pressure indicator:
oConnect two 1/4"F couplers to filter body top
outlets.
Connect two elbow 1/4"M to the couplers.
oConnect elbow 1/4"F to the bottom of the
indicator.
oConnect 1/4"F adaptor to side of the indicator.
oPress fit the indicator to the slots on the filter
body.
oConnect long 20cms tube from Filter inlet port to
indicator bottom (marked "+").
oConnect long 15cms tube from Filter outlet port
to indicator side (marked "-").
oHydraulic fitting may require Teflon to seal.

Installation
•Filter can be installed in vertical position or at 90° to the
pipe, (Flush valve pointing down or to the side).
•Ensure proper flow direction as clearly marked on the
filter.
•Make sure both flush valves are closed.
•It is recommended to install a shut off valve before the
filter for maintenance.

First Operation
•Open the water source and check for leaks.
•Perform 2-3 flushing cycles as outlined below.
•Filter is ready for use.
Flushing the filter
•The disc element needs to be cleaned when the
head loss across the filter reaches 0.5-0.7 bar and
the red pin protrude from the pressure indicator.

•Open the bottom flush valve –picture 7
•Turn the handle ¼+ of a turn until the stop
picture 8
•Wait 15–30 seconds.
•Turn the filter handle back
•Close the bottom flush valve
•Open the secondary flush valve for 10 seconds and
close.
Please note: the strength required to turn the handle
may vary according to the water quality and its source.
Trouble shooting
•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 flush valve.
oRepeat the flushing cycle again, do not forget to open the filter flush valve before turning the
handle.
•Filter is still not clean:
oClean the internal screen by disassembling and flushing manually.
oOpen the filter cup.
oDisassemble the lower thread and remove piston
oCheck that the seal is intact and in its position.
•Filter handle is not turning
oCheck that the flush valve is fully open before turning the handle.
oCheck that water flows through the bottom valve.
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.
oOpen the inlet valve

Periodic Maintenance
Warning:
•Before servicing the filter make sure it is empty of water
and the inlet valve is closed.
•Never open the filter under pressure!
to release pressure open the lower or secondary flush
valve
Secondary flush port
•The secondary flush port should be examined every 30 days or if
the flush cycle does not reduce the head loss (filter does not
flush effectively).
•Disassemble the female coupling with the flush valve. Picture 10.
•Rotate the screen disc counterclockwise and pull out. Picture 11.
•Flush thoroughly under stream of water.
•Return the disc to its place and rotate clockwise until it stops.
•Assemble the coupling with the flush valve and close.
Discs manual cleaning
•The Discs should be cleaned manually at the beginning of the
irrigation season, every 90 days thereafter or if the flush cycle
does not reduce the head loss (filter does not flush effectively).
•Open the tightening ring counterclockwise
•Pull it down and put aside.
•Release the filter cup by shaking it and pulling down.
•Open the lower thread and remove it without dismantling the
spring. Picture 12.
•Remove the piston. Picture 13
•Remove the discs carefully avoiding damage to the seal. Picture
14.
•Flush discs thoroughly under stream of water. Make sure hard
adhesives are removed.
•Return all discs to the spine –make sure you returned all of
them.
•Check that the seal is in its position.
•Return the piston –make certain it is in the correct orientation
and push upwards.
•ATTENTION - In the correct position the 2 rails will slide into
the 2 slots, all other rails have one slot see picture 15
•Tighten the cup to the filter body and position the cup
protrusion opposite the socket in the filter body.
•Return the locking ring to its place and tighten by hand until it
stops.
