Model OF1465, OF1665 OneFlow Chemical-Free, Salt-Free Scale Prevention
Introduction
The Watts OneFlow® Anti-Scale System provides protection from scale formation on internal and external plumbing surfaces. The OneFlow ing to treat both hot and cold water, or it can be located directly before a water heater, boiler, or other water using device that requires protection from hard water.
OneFlow hardness minerals into undissolved crystal microparticles. These crystals stay suspended in the water and have a greatly reduced ability to react and attach to surfaces like dissolved hardness does. Therefore the problem of internal buildup of scale in pipes, water heaters and on fixtures and glass is greatly reduced.
OneFlow antiscalants, sequestrants, etc.. will most likely have to be changed to be compatible with OneFlow washing chemistry will likewise require adjustments.

OneFlow® Benefits
• Chemical free scale prevention. Cost savings and environmental benefits.
• Virtually maintenance free. No salt bags or other chemicals to buy, transport and store.
• No electricity, no wastewater, completely self-contained.
• Improves the efficiency of water-using appliances.
• Simple installation – no electrical and drain hookup.
• Safe for landscaping and lawn watering. No need for costly bypass plumbing.
• Compatible with all on-site and community wastewater treat­ment systems.

Important note 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 should be less than 1.3 mg/L.
Copper
Copper usually originates from new copper plumbing upstream of the OneFlow 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 connec­tions are complete, place the OneFlow to following the startup procedure and flush the plumbing for at least 10 minutes.

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.
IF 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 the OneFlow stall the system near any device or area that would be adversely effected by water.

System Overview
!
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 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.
Notes to the Installer
i
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 trans­portation and installation much easier than conventional sys­tems.
• Because the OneFlow 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.

Using OneFlow® with other water treatment equipment.
Due to the unique properties of OneFlow®, there are some unique requirements for using OneFlow tion or other forms of water treatment.
1. OneFlow not install any filters after OneFlow which scale prevention is required. POU filters, e.g. carbon or RO are exempt from this requirement.

Important Notes!
i
NOTE: We recommend the installation of a dual-union ball-valve on the inlet and outlet to isolate the tank for servicing.
NOTE: A full bypass should be installed so that the full service flow can be routed around the system as needed for servicing.
NOTE: The OneFlow which is opposite of a conventional softener. The inlet is on the bottom, the outlet on the top.

Installation
Tighten the Tank Bushings
Tank bushing. Rotate Clockwise to tighten.
Lay the tank down and check the bushings on the inlet and outlet (bottom and top) of the tank. It is common for them to loosen during shipment. Tighten the bushings with a strap wrench as needed
Install Piping
Connect the inlet and outlet plumbing according to your preferences and any applicable local codes. Include sample/drain ports with hose-bibb con­nections on the inlet and outlet piping to facilitate startup and service.
!
Support the Piping
The full weight of the piping and valves must be supported by uni­strut, pipe hangers or other means. The tank connections cannot sup­port the weight of the piping. This photo from a multi-tank system installation shows properly supported piping.
Start-Up
Connect a hose to the hose bibb on the outlet of the tank. Run the hose to a drain.
Slowly / partially open the supply water ball valve. Allow the tank to slowly fill with water. When a steady stream of water ap­pears at the drain, close the supply valve.
Open the inlet and outlet valves on the system. Transfer the bypass valves from Bypass to the Service position. Open a nearby faucet downstream from the OneFlow
Check for leaks. Repair as needed. The system is now ready for service.
