Notice to Installer

•  Do not discard this manual after installation. This manual contains 

important operation, maintenance and precautionary information . 

Please present this manual to the user/owner/operator after  

installation .

•  It is strongly suggested that you read this manual before installing 

system to ensure the best possible installation .

•  Installation must comply with all local and state plumbing codes 

and regulations . 

•  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 hardness related 

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 .  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 al-

lowed 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 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-corrosivi-

ty water soluble flux listed under the ASTM B813 standard .  OneFlow 

is not 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

* Please note: All cartridge filters are preinstalled, in the  

housings, at the factory.

  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 and 

pressure gauge assemblies . Thread the inlet and outlet valve 

and pressure gauge assemblies into the inlet and outlet of the 

system . The valve and pressure gauge assembly with the ¼" 

(8mm) Quick-Connect flush valve fitting is to be installed on the 

outlet of the system . See the drawings on pages 4 and 5 of this 

manual for proper valve and pressure gauge assembly place-

ment . 

NOTE: DO NOT OVER TIGHTEN THESE FITTINGS 

INTO THE FILTER HEADS. 

  3 .   Anchor the system on a wall stud or suitable mounting material

    spanning wall studs . System must be vertical, upright and level .    
  4 .   Run a suitable line from the tap water source to the inlet ball 

valve on the left side of the system . Slimline models require 3/8

"

 

(10mm) NPT fittings, Big Blue models require 

¾

"

 (20mm) NPT 

fittings . 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.

 

  5.   Select the appropriate size tubing for the equipment being fed, 

and connect it to the outlet ball valve of the system .  

NOTE: DO NOT OVERTIGHTEN CONNECTION FITTING 

INTO BALL VALVE.

  6 .   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 .

  7 .   Once all inlet and outlet piping has been completed, check and 

make sure all filter housing are tight, slowly open the inlet valve 

and allow all air to purge from the system . Slowly close the 

1

4

(8mm) drain valve, allow the system to reach operating pressure, 

and check for leaks .

  8 .   If no leaks are present, open the 

1

4

" (8mm) drain line again and 

allow it to run to drain for 5 minutes to flush the system then 

close the valve . 

  9 .   Open the outlet water valve and check for leaks .
 10 .   Record the start up date and pressure gauge values in system 

maintenance log .

Note:  Overtightening components can damage the system 

causing water damage and/or system failure.
