Introduction
The OneFlow Anti-Scale System for hot water provides pro-
®
tection from scale formation on internal plumbing surfaces
where the hot water feed line is being further heated, such
as a booster heater. These OneFlow systems use specially
designed components to work in applications where the
incoming water is heated between 100°F - 140°F (38°C - 60°C)
but has not yet been treated for scale control. These types of
applications typically involve protecting and extending the life
of equipment and instruments from the damaging effects of
hard water scale.
OneFlow prevents scale by transforming dissolved hardness
minerals into harmless, inactive microscopic crystal particles.
These crystals stay suspended in the water, have a greatly
reduced ability to react negatively like dissolved hardness
does, and eventually find their way to the drain. OneFlow is
particularly useful in higher temperature applications where
scale formation is accelerated. The system requires very little
maintenance, no backwashing, no salt and no electricity.
Typical hardness problems, especially build-up of scale in
boilers and steamers is greatly reduced.
OneFlow is not a water softener or a chemical additive (like
anti-scalants or sequestrants). It is a scale prevention device
with proven third party laboratory test data and years of suc-
cessful residential and commercial installations. OneFlow is
the one water treatment device that effectively provides scale
protection and is a great salt-free alternative to water soften-
ing (ion exchange) or scale sequestering chemicals. Laundry
and warewashing chemistry will likewise require adjustments.
WARNING
!
You are required to consult the local building and plumbing codes prior
to installation. If the information in this manual is not consistent with
local building or plumbing codes, the local codes should be followed.
Inquire with governing authorities for additional local requirements.
OneFlow Benefits
• Chemical-free scale prevention and protection – converts hard-
ness minerals to harmless, inactive microscopic crystals making
OneFlow an effective alternative technology to a water softener
for the prevention of scale due to water hardness
• Virtually maintenance free – no control valve
• System and components designed to work specifically with hot
water applications
• Uses environmentally friendly technology by using no salt or
other chemicals to constantly add, no electricity and no waste-
water
• Improves efficiency of water using appliances and equipment
• Simple sizing and installation – all you need to know is pipe size
and flow rate
• Built-in bypass valve provides flexibility for off-line service or
media replacement
• OneFlow does not remove minerals or add sodium to the water
supply
• Long life media requires replacement once every three years
• Effective retro-fit technology where scale control was not
previously considered
OneFlow media is certified by WQA
to NSF/ANSI/CAN Standard 61 and
NSF/ANSI 372 for Lead Free compliance.
WARNING
!
Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after the
system.
