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 Specifications 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 Teflon
®
tape only .
• Do not solder plumbing connections that are attached to the
housings or inlet/outlet fittings . 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 filter
replacement .
• If water hammer is evident, install water hammer arrestors before
the system .
• Do not over tighten fitting connections.
• Always back up valves and fittings with a wrench when installing
fittings to avoid over tightening or loosening existing fittings .
• Do not install the unit behind equipment where it may be difficult to
access the system for future filter replacements .
Position the system in a suitable location . The direction of flow
through the system is left to right . Keep this in mind when determin-
ing 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 .
OneFlow Application Practices
Note: Systems using OneFlow technology prevent hard water scale
formation inside the plumbing system at influent 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 ad-
verse 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 operat-
ing under normal conditions for a period of 4 weeks prior to starting the
system up . This will allow the copper surfaces to be fully flushed and
develop a natural protective surface . To further minimize any problem
with excess copper, avoid applying excess flux on the inner surfaces
of the pipe and use a low-corrosivity water soluble flux listed under the
ASTM B813 standard . OneFlow is not designed for use on closed loop
systems .
Operation
With sufficient pressure, operation of this system is completely auto-
matic . Dependable operation involves only monitoring system pres-
sure differential, periodic filter changes, and service documentation .
Installation
There is some light field assembly required for this system. Be-
fore 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
filter housings. These drawings will be referenced in the installa-
tion 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 Teflon 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 .
NOTICE
DO NOT OVER TIGHTEN THESE FITTINGS INTO
THE FILTER HEADS.
When installing fittings onto this system,
back any existing receiving fittings with a wrench to prevent
fitting movement . Use a wrench to tighten gauges into their
connection ports . Do not twist on gauge case .
3 . Install the filters into the filter manifold . Make sure all plastic
wrapping and protective plastic caps have been removed from
the filters prior to their installation . Insert the prefilter into its
blue canister . Make sure the blue canister's oring is properly
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 filter placement) . Then install the QT style filter
cartridges . To install these filters, push them into the heads and
give them a quarter twist (clockwise when viewed from below) .
When the filter is completely inserted, the cartridge label will be
front centered .
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 filter housing at this time .
The mounting hardware used must be selected and installed
so that the system is firmly 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
valve on the left side of the system . Brace the inlet ball valve on
the system with a wrench when connecting the feed water line .
NOTICE
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 ball valve of the system .
NOTICE
DO NOT OVERTIGHTEN CONNECTION FITTING INTO
BALL VALVE.
7 . Install the ¼" (8mm) tubing into the Quick-Connect fitting on the
outlet of the system and hold it over a drain . Open the
1
⁄
4
" (8mm)
drain valve .
8 . Once all inlet and outlet piping has been completed, check and
make sure all filter housing(s) are tight, slowly open the inlet valve
and allow all air to purge from the system from the
1
⁄
4
" tubing .
Slowly close the
1
⁄
4
" (8mm) drain valve, allow the system to reach
operating pressure, and check for leaks .
