Notice to Installers
• Connect the system to cold water supply only. Water Temperature
cannot exceed 100°F (38°C).
• System must be installed in a vertical, upright and level position.
• Do not use with water that is microbiologically unsafe or of
unknown water quality.
• Notice to user/owner/operator: Please retain this manual for future
reference for parts, maintenance, or troubleshooting.
• It is recommended that all personnel responsible for operation and
maintenance of this product read the precautions, maintenance,
and operation sections of this manual.
Installation Precautions
• Do not install system on line pressure above the rated pressure as
noted in System Specications above.
• Do not install the system on a hot water line. Failure to limit the
water temperature to 100°F (38°C) can result in housing failure and
property damage.
• Do not connect the system backwards with the feed water line
connected to the outlet.
• Do not use liquid pipe thread compounds for threaded
connections. Use Teon
• Do not solder plumbing connections that are attached to the
housings or inlet/outlet ttings. System damage may occur due to
high temperature.
• Do not allow the system to freeze. Turn off water supply and drain
the system if temperature falls below 32°F (0°C).
• Do not install system in direct sunlight or where the system will be
exposed to harsh chemicals or may be subjected to being hit by
moving equipment, carts, mops, or any other item that may cause
damage.
• Allow 3" (76mm) minimum clearance under the housings for lter
replacement.
• If water hammer is evident, install water hammer arrestors before
the system.
• Do not over tighten tting connections.
• Always back up valves and ttings with a wrench when installing
ttings to avoid over tightening or loosening existing ttings.
• Do not install the unit behind equipment where it may be difcult to
access the system for future lter replacements.
Position the system in a suitable location. The direction of ow
through the system is left to right. Keep this in mind when determining installation locations. Do not mount the system near any source
of heat. Also do not mount this system over anything that may be
adversely affected by water.

tape only.
OneFlow Application Practices
Note: Systems using OneFlow technology prevent hard water scale
formation inside the plumbing system at inuent hardness levels of 75
grains per gallon of calcium carbonate and less. Due to variances in
water chemistry certain aesthetic conditions external of the plumbing
system may not be attained. OneFlow is designed for the treatment of
potable water that meets the requirements of the current USEPA Safe
Drinking Water Act. The addition of soaps, chemicals, or cleaners, before
or after OneFlow treatment, may reverse its anti-scale treatment 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. New copper lines need to be
passivized before placing unit into service. Copper usually originates from
new copper plumbing upstream of the OneFlow system. All new copper
plumbing before the system should be allowed to passivate by operating under normal conditions for a period of 4 weeks prior to starting the
system up. This will allow the copper surfaces to be fully ushed and
develop a natural protective surface. To further minimize any problem
with excess copper, avoid applying excess ux on the inner surfaces
of the pipe and use a low-corrosivity water soluble ux listed under the
ASTM B813 standard. OneFlow is not designed for use on closed loop
systems.
Operation
With sufcient pressure, operation of this system is completely automatic. Dependable operation involves only monitoring system pressure differential, periodic lter changes, and service documentation.
Installation
NOTICE
There is some light eld assembly required for this system. Before beginning the installation of this system, please make sure
all components are present. Compare the contents of this box
to the system drawings located at the end of this manual. As
illustrated by the drawings, some models have separate remote
lter housings. These drawings will be referenced in the installation instruction steps.
1. Turn off all equipment to be fed by the system, locate the water
supply shutoff valve and turn it off.
2. Apply Teon tape to the threads of the inlet and outlet valve
assemblies and pressure gauges (if supplied for your model).
DO NOT USE PASTE TYPE THREAD SEALANT. Thread the
inlet and outlet valve assemblies into the inlet and outlet ports
of the system as shown on the system drawings in this manual.
Install the pressure gauges, if applicable, into the gauge ports as
indicated by the system drawings in this manual.
DO NOT OVER TIGHTEN THESE FITTINGS INTO
THE FILTER HEADS. When installing ttings onto this system,
back any existing receiving ttings with a wrench to prevent
tting movement. Use a wrench to tighten gauges into their
connection ports. Do not twist on gauge case.
3. Install the lters into the lter manifold. Make sure all plastic
4. Anchor the system on a wall stud or suitable mounting material
spanning wall studs. System must be vertical, upright and level.
If applicable, mount the remote lter housing at this time.
The mounting hardware used must be selected and installed
so that the system is rmly pressed against the mounting
surface. The system mounting hardware must keep the system
from moving during routine service and operation.
5. Run a suitable line from the tap water source to the inlet ball

inserted into its oring groove. Thread the housing onto the head
with standard clockwise rotation (when viewed from below).
Hand tighten the blue housing (See the system drawings in this
manual for proper lter placement). Then install the QT style lter
cartridges. To install these lters, push them into the heads and
give them a quarter twist (clockwise when viewed from below).

7. Install the ¼" (8mm) tubing into the Quick-Connect tting on the
outlet of the system and hold it over a drain. Open the
drain valve.
8. Once all inlet and outlet piping has been completed, check and
make sure all lter housing(s) are tight, slowly open the inlet valve

allow it to run to drain for 5 minutes to ush the system. Then
close the valve.

NOTICE
Overtightening components can damage the system causing
water damage and/or system failure.
Maintenance
Routine maintenance of this system involves periodic lter changes.
Filter cartridges should be changed at end of lter life, due to lack of
ltering performance, or whenever a 15 psi pressure drop or greater
is experienced during normal operation, whichever comes rst.
Filter Cartridge Replacement Procedure
!
WARNING
Determine whether all equipment connected to the system must
be turned off prior to shutting off water supply from lters.
1. If required, turn off downstream equipment.
2. Turn OFF water to the system by closing the inlet and outlet ball
valves.
3. Open the ¼" drain valve on the outlet of the system to relieve
pressure in the housings.
4. Remove all lters. The blue lter housings unscrew to the left
when viewed from underneath. They have a standard right hand
thread. The QT style lters are removed by rotating them 1/4
turn to the left and then gently pulling down.
5. Clean inside of blue housing sump(s) with warm water. If desired,
disinfect housing using a teaspoon of household bleach. Add
to lter bowl and ll with water. Let stand 5 minutes and then
discard and rinse.
6. Insert new QT style lters into the manifold assembly. Push up
and twist each QT cartridge 1/4 turn to the right to properly
install it into the manifold assembly. When making the 1/4 turn,
the cartridge label should come to a stop facing you.
7. Insert a new prelter and, if applicable, the remote lter cartridge
into the blue lter housing(s). Check O-ring for damage and
replace if damaged or distorted. Make certain the O-ring is
properly positioned and reinstall the lter housing. Tighten
housings hand tight. OneFlow is always the last lter in the
system.
Do not overtighten lter housing, overtightening may damage
O-ring(s), cause water leaks, or affect system performance.
8. Slightly open the inlet ball valve and fully open the ¼" drain
valve. Once full ow of water ows from the drain port, slowly
open the inlet valve to the full open position. Allow water to ush
to drain for 5 minutes.
9. Slowly close the drain valve and check the system for leaks.
10. Slowly open the outlet valve to restore water ow to downstream
equipment.
11. Record lter change date in system maintenance log.
