Important note about iron,
manganese and copper in the
water supply
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, 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 respec-
tively. Copper should be less than 1.3 mg/L.
Copper
Copper usually originates from new copper plumbing upstream
of the OneFlow system. If this condition exists, we recommend
®
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 to use a low-corrosivity water soluble flux listed
under the ASTM B813 standard. Once the plumbing connec-
tions are complete, place the OneFlow
to following the startup procedure and flush the plumbing for at
least 10 minutes.

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 sys-
tem operates in an upflow, 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 facili-
tate installation and service.
• Observe all local plumbing and building codes when installing
the system.

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 upflow 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 trans-
portation and installation much easier than conventional sys-
tems.
• Because the OneFlow system operates in the Upflow mode,
®
the tank connections are opposite of what you're used to.
• Please see the Important note about iron, manganese and
copper above.
• Please see the note about "Using OneFlow
treatment equipment" on the next page.

Installation Precautions!

• Do NOT install system on line pressure above 125psi.
• Do NOT install the system backwards with the feed water
line connected to the outlet.
• Do NOT install system in direct sunlight or where system is
exposed to harsh chemicals or may be subjected to being
struck by moving equipment, carts, mops or any other item
that may cause damage.
•  I F water hammer is evident, install water hammer arrestors
before the OneFlow
®
• Always back-up valves and fittings with a wrench when
installing a fitting to avoid turning the valve.
• Do NOT install the unit behind equipment where it may be
difficult to access the system for filter replacement.
Position the OneFlow unit in a suitable location. Do NOT install
®
the OneFlow system near any source of heat. Also, do not in-
®
stall the system near any device or area that would be adversely
effected by water.

1. OneFlow must be the last stage in the treatment chain. Do

not install any filters after OneFlow
which scale prevention is required. POU filters, e.g. carbon or
RO are exempt from this requirement.
