Backwash / Regeneration Cycle
The AIO filter is factory preset to backwash / regenerate every third day at 12:30 am. Only untreated water is available during
backwash / regeneration. A complete backwash / regeneration cycle lasts approximately 50 minutes, after which filtered water
service is restored. Homeowners with waters that contain very heavy iron / manganese loading may experience loss of pressure
and/or flow if too much water is filtered between backwash cycles. In this case, the backwash frequency may be reduced to every
other day (or every day in extreme cases). It is not recommend to operate more than 3 days between backwash cycles.
1. Backwash (10 minutes):
The valve piston will drive to the backwash position. Only unfiltered water is available during backwash.
Initially, what remains of the air bubble will be released to drain (the sound of air being released can be heard). Unfiltered raw water
will flow into the control valve through the inlet, down the riser tube, out the distribution basket, and up through the media. This
will fluidize and expand the media bed allowing oxidized iron and manganese and any other particles that were trapped during
service to be dislodged from the media and flushed to drain. The media is also de-compacted and readied for the the air injection
step. After the 10 minutes of flow to drain, the valve piston will drive to the draw position.
The Backwash step can be lengthened, if necessary, but it should never be shortened.
2. Air Recharge (40 minutes):
During this cycle, water flows to drain, creating a suction which allows air to be drawn into the filter. The air forces most of the
water out of the tank allowing the catalytic surface of the media to be recharged with oxygen from the air. The sound of air being
recharged will be heard. Air bubbles should go down to the drain before proceeding to the next step.
After the 40 minutes of air draw, the valve piston will drive back to the service position. As water begins to refill the tank, it will
compress the air and reestablish the air bubble in the top of the tank. Filtered water is available once again. The first draw of treated
water after regeneration may have a milky or cloudy appearance but this will dissipate quickly. It is just a bit of excess air in the
water.
The Air Recharge step can be lengthened, if necessary, but it should never be shortened.
3. Second Backwash (OFF)
4. Rinse (OFF)
Default is Off, but can be set to 1 or 2 minutes. Keep in mind that the longer the rinse cycle, the smaller the air bubble will be.
5. Fill (OFF)
