***NOTE***

Since both calcium carbonate and magnesium oxide increase hardness of your water,

if your dwelling contains a tankless water heater, it is recommended that a water softener be installed

after the ATUN Series Upflow Acid Neutralizer System to help prevent the heater coil from plugging with

hardness material.

About Your ATUN

How Does my Neutralizer Filter Work?

The low pH (acid) water passes through a special limestone neutralizing

media and slowly dissolves the media raising the pH to approximately 7

units (neutral) or higher. Periodic media replenishment is therefore re-

quired. The frequency and amount of media replenishment depends on

the volume of water used and how acidic the water is before treatment.

The lower the pH (acidity) of the water being treated, the greater the at-

trition rate of the media and the slower the water should pass through the

bed. The unit should be sized according to the level of pH and existing flow

rate. Your dealer can provide an estimate of your replenishment require-

ments.

ATUN Series Upflow Acid Neutralizers virtually eliminate the possibility of

media bed "cementing" because the water to be treated actually "up-

flows" through the neutralizer media bed! This procedure requires NO

electricity or backwashing.

A large fill-port permits easy replenishment of the "sacrificial" neutralizing

media by the homeowner or a service technician.

There are different media types available which can be used in this ATUN

Series Upflow Acid Neutralizer System. Each is designed to improve a par-

ticular aesthetic problem. None of them should be used to make non-po-

table water safe to drink. The following descriptions indicate not only what

the media is designed to do, but also points out their limitations.

Neutralizer Blend

Neutralizer media is typically a blend of calcium carbonate and mag-

nesium oxide. This media is used to elevate the pH of acid water and is

generally used when the pH is approximately 5.5 - 6.0 units. The neutral-

izer media dissolves when water with a low pH passes through. The blend

is used to take advantage of the fast, vigorous pH adjusting capabilities of

magnesium oxide and the slow, long-lasting capabilities of the calcium

carbonate. Neutralizer is typically not recommended when the pH of the

raw water is below 5.5 units, because the dissolve rate would be high and

thus constant maintenance of the ATUN Series Acid Neutralizer System

would be necessary. In these cases contact our Customer Service Depart-

ment at 1-877-414-7873 for recommendations.

***NOTE***

Since the neutralizer media dissolves as it elevates pH level, it will in-

crease the hardness of your water. If your dwelling contains a tankless water heat-

er, a water softener must be installed after the ATUN Series Upflow Acid Neutralizer

System to help prevent the heater coil from plugging with hardness material.

Calcium Carbonate

Calcium carbonate can be used when only a slight pH adjustment is

required (typically 6.0 to 6.8 units). Calcium carbonate is sacrificial (dis-

solves) when adjusting pH and will thus increase hardness as well. Re-

plenishment will be required periodically, once again depending on raw

water pH and water consumption.
