    AIO Installation and Startup

    This document describes the installation and setup of your new AIO iron, manganese, and sulfur reduction system. You delivery will consist of three boxes:

    • Box 1 is a tall tank containing the cylindrical media tank
    • Box 2 is a smaller but heavy box containing supplemental media
    • Box 3 is the lightest box and contains the control valve, funnel, and power supply


    For Box 1 ensure the tall media tank box is standing with the "this side up" sticker at the top. Carefully cut down one of the corners of the box with a pair of scissors or a box cutter. If a box cutter is used it's very important that the shortest blade setting is used so that the tank is not scored or cut and that the cut is made directly on the corner and not on the side of the box.

    For Box 2 carefully cut the tape at one end of the box and slide the three packs of media out of the box.

    For Box 3 carefully cut the tape and remove the control valve and funnel.

    Setting Up The Media Tank

    Once one side of the box has been removed from the media tank, roll or pull the tank out of the box and position the tank roughly where the system will be installed. If you find that the base of the tank is askew, first ensure that the tank cap is on and lie the tank on it's side. Tap the tank base with a rubber mallet to reposition it.

    The Control Valve

    AIO labelled


    • remove the cap from the media tank
    • place a piece of tape on the top of the exposed riser tube (1" diameter grey tube)
    • place the funnel on the top of the tank
    • Add media Bag 1 to the tank
    • Add media Bag 2 to the tank
    • Add media in last bag to the tank (this bag is the remaining Katalox Light media)
    • Remove the funnel and the tape from the riser tube
    • Brush and media off the tank threads
    • Lubricate the upper lip of the tank (white) either with silicone lubricant or any vegetable based cooking oil
    • Lubricate the outer surface of the top 1" of the riser tube with same
    • Lower the control valve onto the tank while guiding the riser tube into the center of the underside of the control valve
    • Thread the valve down onto the tank until it's snug, then 1/8 of a turn more (over-tightening can lead to tank damage)

    Plumbing Notes

    • If looking at the control valve from the front, untreated water enters the system from the right, and exits to the left
    • The threads on the system are 3/4" NPT which are a standard tapered thread. Teflon tape is recommended to be used on the threads.
    • Ensure that the weight of the plumbing is supported and not hanging from the bypass assembly. It's recommended to affix inlet/outlet plumbing to the wall. Failure to do so can result in a leak in the bypass valve area
    • The drain line must have no smaller than 1/2" inner diameter and it's recommended that the drain line not exceed 15 feet
    • When this system backwashes it will discharge both air and water so ensure that the drain location can receive both
    • A gear clamp (sometimes called a worm clamp) is highly recommended for keeping the drain line connected to the drain line barbed fitting
    • The handles of the bypass should be initially positioned so they are pointing towards each other. This is the "bypass" position
    • A 3/4" plumbing supply (or larger) is required for the proper operation of the system

    System Startup

    • Once the system has been plumbed and the bypass valve is in the bypass position, partially open the inlet side of the bypass valve to slowly fill the media tank with water.
    • When the media tank is full of water plug the control valve into a standard electrical receptacle (this video shows where it plugs into the control valve)
    • Press and hold the UP or DOWN arrow on the control valve until the clock starts to move and set the proper time of day. Note that PM is displayed while AM is not. Once the correct time of day is displayed, press the leftmost button once to enter it (but don't hold this button down)
    • Open the outlet side of the bypass valve
    • Initiate a backwash by pressing and holding the leftmost button until the control valve motor engages, then release
    • The system will go through the following backwash stages:
      • 14 Minute Backwash
      • 40 Minute Air Draw
      • 4 Minute Rinse
    • It's important that the first backwash is initiated no more than 6 hours after the media tank has been filled with water. There are "fines" in the media that need to be rinsed out of the tank right away or it can cause clumping of the media that can interfere with proper system performance.

    Your system is now ready to filter and will automatically backwash every two days at 2:00am.
