1. Turn off all equipment to be fed by the OneFlow
®
System,
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
®
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
3
/
4
" full-flow ball valve on the water supply side
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
3
/
4
" full-flow ball valve at the
tap water source to the inlet ball valve on the left side of
the OneFlow
®
system. Use 2-3 wraps of Teflon
®
tape and
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
®
System.
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 filters.
7. With OneFlow
®
inlet valve closed, slowly open the
3
/
4
" full-
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.
12. Attach the Service Log to the installed OneFlow
®
System
and fill in install date.
