• Contaminated water flows from the inlet manifold through the backflush valves and through the filter.
• The water pressure increases on the outside of the filter element compressing the rings tightly together.
• Grooves in the rings criss-cross, forming a network that traps both organic and inorganic contaminants from the water source.
• This design filters the dirty water thoroughly - not only on the outer surface of the cylindrical disc filter element, but through the entire depth of every ring groove.
• Clean water exits the filter and flows through the outlet valve to the system.

• A pressure differential switch activates the controller at 7 psi differential. During the backflush cycle, the solenoid closes both valves.
• Water flows through the bypass filter to the spine in the reverse direction and separates the discs.
• A specially designed nozzle system inside the filter spine sprays pressurized water against the loosened discs, spinning them clean quickly and efficiently.
• After backflushing, the stack of discs automatically compress to resume filtration.
• Dirty water discharges through the flush port.
• During the backflush time of 20 seconds, there is no water flow to the field.

Note:  Inspect bypass filter on a regular basis; frequency is based on quality of the water.

• Leakage

• Solenoid
• Downstream Pressure and Drain

• Close the water inlet after backflushing the system.
• Make certain there is no pressure in the system.
• Remove the cover by opening the clamp.
• Unscrew the butterfly nut on the filtration element and remove the tightening cylinder.
• Remove the disc set and tie the set on a string.
• Place the discs in a cleaning solution, 10% Chlorine solution for 30 minutes for algae and organic material and Muratic acid for 30 minutes for iron bacteria.
• Thoroughly rinse the discs with fresh water and reassemble the discs on the spine.
• Check that the correct level of discs are assembled on the spine: compress the discs with two hands and make sure that the top disc reaches the imprinted circle on the outside of the spine.
• Reassemble the tightening cylinder and tighten the butterfly nut. Use the butterfly wrench to ensure that the nut is sufficiently tightened.
• Reassemble filter cover and tighten the clamp.
• Check and clean finger filter.
