Installation
Installation Drawings & Dimensions
1. Turn off all equipment to be fed by the OneFlow
locate water supply cut-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
in conjunction with other scale inhibitors. Remove the scale
inhibitors from the water line or discontinue installation.
3. Install a / " full-flow ball valve on the water supply side that

will feed the water system.
4. Anchor the OneFlow
®
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® 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
NOTE: DO NOT connect the tubing to the equipment at
this time. Prior to making connection to the equipment,

Installation Precautions!

• Do NOT install system on line pressure above 125psi.
• Do NOT install system on HOT water line. Failure to limit line
temperature to 100°F may result in housing failure and damage.
• Do NOT install the system backwards with the feed water line
connected to the outlet.
• Do NOT use liquid pipe compounds for fitting connections.
USE two to three wraps of Teflon® tape.
• Do NOT solder plumbing connections attached to filter hous-
ing or inlet valve. Inlet valve and filter housing will be damaged
by high temperature.
• Do NOT allow system to freeze. Turn off water supply to
housing and drain housing if temperature falls below 32°F.
• 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.
• ALLOW a minimum of 3" under the housing to allow for filter
replacement.
• IF water hammer is evident, install water hammer arrestors
before the OneFlow unit.
®
• Do NOT overtighten fitting connections into inlet valve or
housing outlet.
• 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 unit in a suitable location. The direction of
®
flow through the OneFlow
mind when determining installation location. Do NOT mount the
OneFlow system near any source of heat. Also, do not mount
®
the system above any device or area that would be adversely
affected by water.
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
®
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 min-
utes 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
and fill in install date.
