Product Overview: Media Options:

The APUN Series Upfl ow Acid Neutralizer helps prevent corrosion of
copper pipes and plumbing fi xtures by effectively raising low pH (acidic)
water. The APUN Series Upfl ow Acid Neutralizer directs the acidic water
through a special limestone and limestone blended media bed. The acidic
water is neutralized as it slowly dissolves the media, thus automatically
raising the pH level.

The design of the APUN Series Upfl ow Acid Neutralizer, which draws
water upward through the media bed, greatly reduces the potential caking
of the media. The simplicity of the upfl ow design requires no electricity,
backwashing or a drain, making the APUN Series Upfl ow Acid Neutralizer
a simple, effective and economical solution for acidic water.

Easy Installation:

The APUN Series Upfl ow Acid Neutral­izer is easily installed on cold water
lines only. It should be installed after
the pressure tank and prior to any water
treatment device.

A boiler drain is provided for fl ushing the
neutralizer after installation and media
replenishment.

Media Material Application

C Calcium Carbonate Neutralization of acidic water as low as 6.0 units

N Special Blend Media Neutralization of acidic water below 6.0 units

Maintenance*

The fi lter media requires periodic replenishment depending on the amount of water
used and the degree of acidity. The neutralizer should be checked every 3-6 months
to make sure that the media is no more than 2” below the media fi ll line. The fi ll­port located on the top of the tank permits simple replenishment of the “sacrifi cial”
media.

The “C” or “N” Media helps to prevent the corrosion of copper pipes and plumbing
fi xtures by raising low pH (acidic) water conditions. This process is similar to
adding lime to acidic soil or taking an antacid. “C” Media is used for moderate
pH levels (6.0-6.7 units). “N” Media, which dissolves more rapidly, is used for
more extreme conditions (pH 5.5-6.0 units and as low as 5.0 units under certain
conditions). Both types of media are consumed during neutralization and must be
replenished periodically. The “N” or “C” Media is available in 0.5 cu. ft. pails for
periodic replenishment.

The neutralizing media will help to increase the hardness level, along with the pH
level in the treated water. Under higher hardness conditions, a water softener or a
scale reduction fi lter is recommended for post-treatment to soften the water or help
protect the hot water system.
