Iron and Manganese
Just as with conventional water softening media, OneFlow
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. However,
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 should be less than 1.3 mg/L.

Cautions!
• Do not let the system freeze. Damage to the tank 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.
Copper
Copper usually originates from new copper plumbing upstream
needs

of the OneFlow
®
waiting 3-4 weeks before placing the system in operation. 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 excess flux on the inner surfaces
of the pipe and use a low-corrosivity water soluble flux listed
under the ASTM B813 standard. Once the plumbing connections
are complete, place the OneFlow
lowing the startup procedure and flush the plumbing for at least
10 minutes.

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 transpor-
tation and installation much easier than conventional systems.
• Because the OneFlow
the tank connections are opposite of traditional installations.

copper in the water supply" above.

treatment equipment" on the previous page.
