OneFlow
®
+ System Benefits
• Reduces sediment, chlorine taste and odor
• Chemical-free scale prevention and protection – converts
hardness minerals to harmless, inactive microscopic crystals
making OneFlow
®
+ systems an effective salt-free alternative
to ion exchange water softeners
• Virtually maintenance free – No salt bags or other chemicals
to constantly add or maintain
• No control valve, no electricity and no wastewater
• Environmentally friendly technology adds no salt or chemicals
to the water system
• Improves efficiency of all water heating devices and
downstream plumbing components
• Simple installation – standard 1" connections
• Excellent system for homes where equipment protection
is desired for longer equipment life and reduced energy
consumption
• OneFlow
®
+ cartridge-based systems are easily maintained
• Easily installed mounting bracket and multi-function tool
included to allow cartridge change-outs when necessary
Equipment Specifications
Watts OneFlow
®
+ systems are complete, self-contained, loaded
with media and ready to use. A simple inlet and outlet connection
is all that is required for installation. Please review operating
pressures, temperatures and water chemistry limitations to
ensure compatibility and performance.
Setup
Unpack and check the system components for damage or
missing parts.
Installation Considerations
Consider the following points when determining where to install
the system:
• Do not install the system where it would block access to the
water heater, main water shutoff, water meter, or electrical panels.
• Install the system in a place where water damage is least likely
to occur if a leak develops.

Using OneFlow
®
+ System 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 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 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 soften 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.

The overall height and the height of the inlet fitting varies due to material variations and assembly tolerances.
Please allow additional clearance above the system for making connections and replacing cartridge filters.
