Section 1: General Information

Read this manual carefully and follow the installation steps in order.
This iron filter is intended to be an effective and economical way to remove iron from water without the use of messy and

dangerous chemicals or expensive pumps or an external venturi. The valve uses a patented construction to create an air

bubble at the upper portion of the tank to oxidize any ferrous iron prior to being filtered by the media.
The 2510AIO Valve requires annual maintenance. Please contact your dealer for maintenance kits (Part #92359).

How does the Chemical Free 2510AIO Iron Filter work?

This filter works by adding oxygen to the incoming water by passing it through a bubble of compressed air. The water is

then passed through a special filter bed.
The special media not only increases the pH of the water to enhance iron removal but also acts as a physical barrier to

trap iron precipitate.
As more water passes through this iron filter, the oxygen in the unit is used up, and the media gets loaded with iron.

The regeneration process then begins in order to replenish the supply of oxygen, and to backwash the precipitated iron

trapped in the media bed.
The iron removal efficiency will be more effective with high pH water.
Optional Media Beds:

• Birm - Removes iron and manganese from water. Recommended for high pH water.

• nextSand - Traps precipitated iron from the water. Recommended for high pH water.

2510AIO Standard Chemfree Filter

This special media not only increases the pH of the water to enhance iron, manganese and hydrogen sulfide removal but

also acts as a physical barrier to trap iron precipitate.
The filter will automatically adjust the pH to neutral or higher on acid water without an acid neutralizer. The ability to raise

pH greatly enhances the filter’s ability to remove iron efficiently.
Replenishment of this media that raises pH will be required periodically, depending on how low the raw water pH is the

amount of manganese (Mn) present in the water and usage rate.

2510AIO Birm Filter

This media acts as a catalyst for the removal of iron and manganese from the water but require pre-oxidation. The water

is pre-oxidized from the air bubble on the top of the tank and this media removes the iron and manganese from the

water. This is not recommended to remove hydrogen sulfide from the water and requires high pH water.
The media is not sacrificial hence no replenishment is required.

2510AIO nextSand Filter

The water is hydrocharged from the air bubble on the top of the tank and precipitate iron from the water. This media

will effectively remove the precipitated iron from the water to the size of 3-5 micron. Require high pH water and not

recommended for very high (>30ppm) of hydrogen sulfide.
