WARNING!
Installation with copper (Cu)
*** We do not recommend to install OneFlow
per pipes or devices. Excessive copper levels can foul the
OneFlow media. If NEW copper lines or devices had been
®
installed, they need to be passivated for a minimum of 4 weeks
before placing the device into service.
WARNING!
Closed systems/still water
Avoid use in closed circuits (eg hydronic systems) and low
flow installations or standing water (max. 72 to 120 hours,
depending on the quality of the incoming water).
• Do not apply any other antiscalants before or after OneFlow
• You are required to consult the local building and plumbing
codes prior to installation. If the information in this manual
is not consistent with local building or plumbing codes,
the local codes should be followed. Inquire with governing
authorities for additional local requirements.
• Need for periodic inspection and yearly maintenance:
Periodic inspection and yearly maintenance by a licensed
contractor is required. Corrosive water conditions and/or
unauthorized adjustments or repair could render the device
ineffective for service intended. Regular checking and clean-
ing of the devices internal components and check stops
helps assure maximum life and proper product function.
Frequency of cleaning and inspection depends upon local
water conditions.

3. Drill the wall and insert the dowels. Screw the bracket tightly to
the wall. The system must be vertical and upright.
4. Remove the OneFlow housing shell from the housing cap and
®
make sure that the O-ring is correctly in place. When attaching
the shell back to the cap, make certain the O-ring is properly
positioned.
5. Connect OneFlow by using PTFE tape. Use two to three
®
wraps of PTFE tape on the fitting connection. Be careful to
always follow the direction of the flow indicated by the
arrow on the OneFlow housing.
6. Run a suitable line from the
tap water source to the inlet ball valve on the left side of the
OneFlow system. Use 2-3 wraps of PTFE tape and brace the
®
inlet ball valve on the system with a wrench when connecting
7. Select the appropriate size tubing for the equipment being
fed and connect it to the outlet of the OneFlow
NOTE: 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
system could be provided in the line to facilitate flushing when
changing cartridges.
8. With OneFlow inlet valve closed, slowly open the
®
ball valve at the tap water source. Check for leaks.
9. If a drain valve was not installed on the outlet side of the
system, 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 specified system flow rate to allow air bubbles to escape.
NOTE: NO ACTIVATION IS REQUIRED FOR THE OneFlow
SYSTEM TO PERFORM
RECOMMENDED TO ALLOW AIR TO ESCAPE THE SYSTEM.
10. Make certain that the end of the tubing to be connected
to the equipment is clean and sanitary.
11. Connect tubing to equipment. Open all water supply valves
and check for leaks.
12. If no leaks, turn on equipment and check for normal operation.
13. Register the OneFlow system to ensure proper operation.
