Installation
1. Turn off all equipment to be fed by the OneFlow
locate water supply shutoff valve and turn OFF.
2. Determine if the water line has an existing water treatment
system. If so, examine system for use of polyphosphate or
other scale inhibitors. OneFlow
in conjunction with other scale inhibitors. Remove the scale
inhibitors from the water line or discontinue installation.
3. Install a

that will feed the water system.
4. Anchor the OneFlow
system on a wall stud or suitable
®
mounting material spanning wall studs. System must be
vertical and upright.
5. 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 Teflon
®
brace the inlet ball valve on the system with a wrench
when connecting the feed water line. NOTE: 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
NOTE: DO NOT connect the tubing to the equipment at this

system could be provided in the line to facilitate flushing
when changing filters.
7. With OneFlow

flow ball valve at the tap water source. Check for leaks.
8. 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 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.
