Watts OneFlow OF744-10 Manuel D'installation, D'utilisation Et D'entretien page 2

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 hard-
ness concerns. A system may also be installed further down-
stream 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 nec-
essary. 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 addi-
tives 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.
CAUTION
!
• 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 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 install-
ing the system.
WARNING
!
Using OneFlow
®
equipment.
Due to the unique properties of OneFlow
unique requirements for using OneFlow
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
es for which scale prevention is required. POU filters, e.g.
carbon, RO or Ultraviolet (UV) are exempt from this require-
ment.
2. Do not apply any other antiscalants before or after OneFlow.
3. The addition of soaps, chemicals, or cleaners, before or
after OneFlow treatment, may reverse its anti-scale treat-
ment 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.
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).
