Notes About Certain
Contaminants
*Iron and Manganese
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.
**Copper
Pursuant to the EPA drinking water standards, the OneFlow
®
+
Feed Water Chemistry Requirements permit up to 1.3 ppm of
copper. High levels of copper can otherwise foul the OneFlow
®
+
system. If the plumbing upstream of the OneFlow
®
+ system con-
tains copper or new copper plumbing is installed upstream of the
OneFlow
®
+ system, wait a minimum of four weeks before using
the OneFlow
®
+ system. This will allow the copper surfaces to be
fully flushed and develop a natural protective surface.
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.
The OneFlow
®
+ system should not be used on closed loop
systems.
***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 the plumbing system difficult to remove.
NOTICE
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.
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
®
+ system
with other water treatment equipment” on page 2.
• This system is designed for residential applications only.
