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 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 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.
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).
Installation
1. Turn off all equipment to be fed by the OneFlow system,
locate water supply shut off valve and turn OFF.
2. Determine if the water line has an existing water treatment
system. If so, examine system for use of polyphospate or
other scale inhibitors. OneFlow will not be effective if used
in conjunction with other scale inhibitors. Remove the scale
inhibitors from the water line or discontinue installation.
3. Install a user supplied ball valve on the water supply side
that will feed the water system.
4. Anchor the OneFlow system on a suitable mounting
surface that can support the weight of the system while
in operation. System must be vertical and upright.
5. Run a suitable line from the user supplied ball valve at the
tap water source to the inlet ball valve on the OneFlow sys-
tem. Use 2-3 wraps of Teflon
nection and brace the inlet ball valve on the system with a
wrench when connecting the feed water line.
NOTICE
DO NOT OVERTIGHTEN CONNECTION FITTING INTO
BALL VALVE.
6. Select the appropriate size tubing for the equipment being
fed and connect it to the outlet of the OneFlow system.
NOTICE
DO NOT connect the tubing to the equipment at this time.
Prior to making connection to the equipment, this line will
be used to facilitate flushing the system. As an option, a
drain valve in a tee on the outlet side of the OneFlow sys-
tem could be installed in the line to facilitate flushing when
changing filters.
7. With OneFlow inlet valve closed, slowly open the ball valve
at the tap water source. Check for leaks.
8. If a drain valve was not installed on the outlet side of the sys-
tem, hold the tubing that will connect to equipment in a clean
bucket or over sink or drain. Open the system inlet feed valve
and allow water to flush through system for 2 minutes at the
system's rated flow rate to allow air bubbles to escape.
NOTICE
NO ACTIVATION IS REQUIRED FOR THE OneFlow system
TO PERFORM PROPERLY. FLUSHING IS RECOMMENDED
TO ALLOW AIR TO ESCAPE THE SYSTEM.
9. Make certain that the end of the tubing to be connected to
the equipment is clean and sanitary.
10. Connect tubing to equipment. Open all water supply valves
and check for leaks.
11. If no leaks, turn on equipment and check for normal operation.
12. Attach the Service Log to the installed OneFlow system
and fill in install date.
The system is now ready for operation.
