• Not for use on closed loop systems.
• 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 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 facilitate
installation and service.
• Observe all local plumbing and building codes when installing
the system.
CAUTION
!
Using OneFlow
®
with other water treatment
equipment.
Due to the unique properties of OneFlow
®
, there are some
unique requirements for using OneFlow
®
in conjunction with
filtration or other forms of water treatment.
1. OneFlow
®
must be the last stage in the treatment chain.
Do not install any filters after OneFlow
®
or before any devices for
which scale prevention is required. POU filters, e.g. carbon, RO
or Ultraviolet (UV) are exempt from this requirement.
2. Do not apply phosphate or any other antiscalant before or after
OneFlow
®
.
3. The addition of soaps, chemicals, or cleaners, before or after
OneFlow treatment, may reverse its anti-scale treatment effects
and/or create water with a heavy residue or spotting potential.
Any adverse conditions caused by the addition of soaps,
chemicals, or cleaners are the sole responsibility of the end user.
4. OneFlow is not a water softener and does not softener
the water - Water treatment chemistry (e.g. antiscalants,
sequestrants, soaps, chemicals or cleaners etc...) will most likely
have to be changed to be compatible with OneFlow treated
water. Laundry and ware-washing chemistry will likewise require
adjustments.
WARNING
!
Specifications
A OneFlow
®
scale prevention system shall be installed on the main
water service pipe just after it enters the building, but after other
whole building water safety devices (backflow preventers or pressure
reducing valves), to effectively address water hardness concerns. A
system may also be installed further downstream to protect specific
equipment or areas within a plumbing system. The system shall
be plumbed with a bypass valve to allow isolation of tank(s) and
to allow the bypass of untreated water in the event that service or
media replacement be necessary. The installation area should be
suitable in size for the tank(s) to be serviced without encumbrance
and sit upright on a flat level surface.
The system must operate in an upflow manner and does not require
additional water to backwash, flush, or regenerate once put into
service. The system does not require any chemical additives and
does not require electricity for operation.
Standards
Independent scientific testing has confirmed Template Assisted
Crystallization (TAC) technology provides scale reduction of over
95+%. Testing was conducted under protocol based on DVGW
W512 test to access control of scale formation.
Important notice about iron, manganese and copper in the
water supply.
Iron and Manganese
Just as with conventional water softening media, OneFlow
®
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 copper
concentration permitted is up to 1.3 ppm. Typically originating from
new copper plumbing, high levels of copper can foul OneFlow
media. 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.
NOTICE
NOTICE
Spotting May Occur on External Plumbing
Surfaces
OneFlow media systems perform best in single pass potable water
applications with NO additional chemical additives. Depending on
hardness, soft scale spotting may occur. Soft scale spots in most
cases can be easily wiped down with a damp cloth and will not form
hard scale deposits. A Point of Use (POU) Water Softener should
be used on mandatory spot-free applications (e.g. glass stemware,
dishware).
