NOTICE
Not for use on closed loop systems.
* Systems using OneFlow
®
ling lime-scale formation inside the plumbing system at influ-
ent hardness levels up to 75 grains per gallon (1282 mg/l) of
calcium carbonate. Due to variances in water chemistry, 30
grains per gallon is a recommended hardness maximum due to
potential aesthetic issues related to soft scale residue formation
outside of the plumbing system. Testing should be performed to
determine proper application where hardness levels exceed 30
grains per gallon.
**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.
WARNING
!
***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. New Copper lines need to be passivated
for a minimum of 4 weeks before placing unit into service.
For applications with copper concentration greater than 1.3
ppm, please consult Watts Water Quality Technical Service.
To further minimize any problem with excess copper, avoid
applying excessive flux on the inner surfaces of the pipe and
use a low-corrosivity water soluble flux listed under the ASTM
B813 standard.
† 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.
†† All other contaminants must meet the requirements of the
USEPA Safe Drinking Water Act. Specific Mineral and Metal
MCL's, identified in Watts published Feed Water Chemistry
Requirements, supersedes the USEPA SDWA.

OneFlow
systems are complete,

self-contained, loaded with media,
and ready to use. A simple inlet and
outlet connection is all that is re-
quired for installation. Please review
operating pressures, temperatures
and water chemistry limitations to
ensure compatibility.
