Watts OneFlow OF817-8H Manual De Instalación, Operación Y Mantenimiento página 2

Specifications
A OneFlow scale prevention system for hot water shall be
®
installed on the hot water feed line just prior to the equipment
it is intended to protect. The temperature of the hot water
feed line should consistently range between 100°F – 140°F (or
38°C – 60°C) as all of the components are designed to work
in this elevated temperature condition. The OneFlow
shall effectively reduce water hardness scale concerns thereby
protecting heat-transfer and other surfaces from the negative
effects of scale. The system shall be furnished with a factory
supplied bypassvalve to allow isolation of tank(s) and to allow
the bypass of untreated hot 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 encum-
brance and for the tank to 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.
NOTICE
Not for use on closed loop systems.
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.
• Must be used on hot water. This system is not designed for
cold (<100F) water. For cold water operation contact your
Watts Representative for a system designed for cold water
operation.
• 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 facilitate
installation and service.
• Observe all local plumbing and building codes when
installing the system.
WARNING
!
Using OneFlow
equipment.
Due to the unique properties of OneFlow
unique requirements for using OneFlow
system filtration or other forms of water treatment.
®
1. OneFlow
Do not install any filters after OneFlow
which scale prevention is required. POU filters, e.g. carbon, RO
or Ultraviolet (UV) are exempt from this requirement.
2. Do not apply 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, chemi-
cals, 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, seques-
trants, 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).
