systems are complete, self-contained, loaded
with media and ready to use. A simple inlet and outlet connec-
tion is all that is required for installation. Please review operat-
ing pressures, temperatures and water chemistry limitations to
ensure compatibility.

Using OneFlow
®
with other water treatment
equipment.
Due to the unique properties of OneFlow
®
, there are some
unique requirements for using OneFlow
®
in conjunction with filtra-
tion or other forms of water treatment.
1. OneFlow
®
must be the last stage in the treatment chain. Do
not install any filters after OneFlow
®
or before any devices for
which scale prevention is required. POU drinking water filters,
e.g. carbon or RO are exempt from this requirement.
2. The addition of soaps, chemicals, or cleaners, before or after
OneFlow treatment, may reverse its anti-scale treatment
effects and/or create water with a heavy residue or spotting
potential. Any adverse conditions caused by the addition of
soaps, chemicals, or cleaners are the sole responsibility of the
end user.
* See note about iron, manganese and copper on the next page.
Pressure drop at peak flow rate is less than 10 psi.

at a common elevation and 80 degree feed water.

WARNING
!
**Copper
Pursuant to the EPA drinking water standards, the copper
concentration permitted is up to 1.3 ppm. Typically originat-
ing from new copper plumbing, high levels of copper can
foul OneFlow media. For applications with copper concentra-
tion greater than 1.3 ppm, please contact Watts Pure Water
Technical Service at 1-800-224-1299. To further minimize
any problem with excess copper, avoid applying excessive
flux on the inner surfaces of the pipe and use a low-corrosivi-
ty water soluble flux listed under the ASTM B813 standard.
NOTICE
***Silica
OneFlow
®
media does not reduce silica scaling. While silica
tends to have a less significant effect on scale formation than
other minerals, it can act as a binder that makes water spots
and scale residue outside th plumbing system difficult to
remove. This 20 ppm limitation is for aesthetic purposes.
NOTICE
*Iron and Manganese
Just as with conventional water softening media, OneFlow®
media needs to be protected from excess levels of certain met-
als that can easily coat the active surface, reducing its effective-
ness over time. Public water supplies rarely, if ever, present a
problem, but if the water supply is from a private well, confirm
that the levels of iron (Fe) and manganese (Mn) are less than
0.3 mg/L and 0.05 mg/L, respectively.
