trolling lime-scale formation inside the plumbing system at
influent hardness levels up to 30 grains per gallon (513 ppm
CaCO3) 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
metals that can easily coat the active surface, reducing its
effectiveness 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 cop-
per concentration permitted is up to 1.3 ppm. Typically
originating from new copper plumbing, high levels of cop-
per 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 concentra-
tion 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.
NOTICE
† 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 the 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.

CAUTION
!
• Do not let the system freeze. Damage to the housing
may result.
• System must be operated in a vertical position. Do not lay
it down during operation. The system may be placed in any
position for shipping and installation but must be operated
in the vertical position.
• Place the system on a smooth, level surface. Because
the system operates in an UP-Flow, fluidized bed mode,
having a level surface is more important than with a softener
or media filter.
• A bypass valve should be installed on every system to
facilitate installation and service.
• Observe all local plumbing and building codes when
installing the system.
®
• All new copper pipe and fittings used in the installation
of this system should be allowed to self passivate, under
normal operation and water flow, for a period of 4 weeks
minimum before placing the unit into service.
• If making a soldered copper installation, do all sweat
soldering before connecting pipes to the bypass valve.
Torch heat will damage plastic parts.
• When turning threaded pipe fittings onto plastic fittings, use
care not to cross-thread.
• Use PTFE tape on all external pipe threads. Do not use pipe
joint compound.
• Support inlet and outlet plumbing in some manner (use pipe
hangers) to keep the weight off of the bypass fittings.
• Do not use on water that is microbiologically unsafe or of
unknown quality.
NOTICE

Notes to the Installer

The OneFlow + system differs from a conventional softener or
®
media filter in a number of key respects.
• The system is light and only partially filled with media. This is
normal. The UP-flow operation of the system requires a lot
of freeboard to allow the bed to fully fluidize.
• The system has no underbed so you can tip the system
over without any fear of upsetting the media. This makes
transportation and installation much easier than convention-
al systems. Must be installed in VERTICAL POSITION.
• Please see the "Notes About Certain Contaminants"
section on page 3.
• Please see the note about "Using the OneFlow
with other water treatment equipment" on page 2.
• This system is designed for residential applications only.
