    1. See typical installation on page 7 (Fig 2). The Neutralizer is installed after the pressure tank. 2. Make sure to connect the IN pipe to the 7800 inlet and the OUT pipe to the outlet (see Fig 2). As you face the 7800 control from the front, the water enters on the right and exits on the left.

    7. The drain line tubing (not supplied) is connected to a drain from the drain outlet using flexible ½” ID tubing. Note that the drain can run up above the 7800 control and into a drain, it does not have to drain down, as the filter backwashes under line pressure from your well pump. Most plumbing codes require an air-gap connection, so that if your sewer or septic tank backs up, it cannot cross connect with the drain tubing.

    (#3). 11. Note that the 7800 is usually shipped in the bypass position. There is a bypass valve knob on both the inlet and the outlet. You can easily tell if it is in bypass because the two knobs will be in line with each other (Fig 4).

    7800 Neutralizer Installation & Startup Guide 7800 Neutralizer up to 4 feet above the top of the tank. If the drain line will be more than 20 feet, use larger diameter tubing such as ¾” or 1”. Note that it is desirable to be able to run the drain line into a bucket in order to test the backwash flow rate in the future.

    First open the Inlet Side of the bypass valve. Second slowly open the Outlet Side of the bypass until it is in the full service position. The 7800 bypass valve knobs are a little stiff, so you can use Allen wrench placed in the holes to turn the knobs. Turn the bypass valve knobs in the correct direction which is counter-clockwise as you face the bypass valve knobs.
