Notice to Installer

• Do not discard this manual after installation. This manual contains important operation, maintenance and precautionary information. Please present this manual to user/operator/ owner after installation.

• It is strongly encouraged that you read this manual before installing the system to ensure the best possible installation.

• Installation must conform to all local and state plumbing codes and regulations.

• Connect system to cold water supply only. Water temperature cannot exceed 100°F/28°C.

• System must be installed in a vertical, upright and level

position.

• OneFlow

systems must not be used in conjunction with

polyphosphate or any other scale inhibitor.

• Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.

• Notice to user/operator/owner: 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, operation and maintenance sections of this manual.

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 housing

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 through the OneFlow when determining installation location. Do NOT mount the OneFlow

unit in a suitable location. The direction of ﬂow

unit is always left to right; keep this in mind

system near any source of heat. Also, do not mount the system above any device or area that would be adversely effected by water.

Installation

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 in conjunction with other scale inhibitors. Remove the scale inhibitors from the water line or discontinue installation.

3. Install a

/2” 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 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 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 the line to facilitate flushing when changing filters.

7. With OneFlow

inlet valve closed, slowly open the 1/2” 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.

Filter Change Frequency

The ﬁlters should be changed in response to the following conditions. OF140RM • 12 months since installation or last ﬁlter change.

Replacement Filter Cartridges

OneFlow® systems can only be used with OneFlow® ﬁlter car-

tridges. Use of replacement cartridges other than those speciﬁed will void warranties, certiﬁcations and may compromise equipment protection, water quality and equipment life.

Filter Cartridge Replacement Procedure

IMPORTANT: Determine whether all equipment connected to the OneFlow water supply from filters.

1. If required, turn off equipment.

2. Turn OFF water to OneFlow

3. Press the red button to release pressure.

4. Remove housing(s) - use filter wrench if necessary.

5. Clean inside of housing sumps with warm water. If desired, disinfect housings using a teaspoon of household bleach. Add to filter bowl and add water. Let stand 5 minutes and discard.

6. Insert new cartridges into filter housings. Match cartridge model numbers to model numbers on bracket.

7. Make certain the O-ring is properly positioned and reinstall filter housings (hand tighten only). Check O-ring for damage and replace if damaged or distorted.

8. Slightly open the inlet ball valve; push the red pressure relief button to release trapped air until a small amount of water comes out - release the red button and fully open the ball valve.

9. Open the flush valve downline from the filter housing (if equipped) and flush the new cartridges to drain or bucket for two (2) minutes or until water runs clear. If no flush valve is present, disconnect line from equipment to flush to drain.

10. VERY IMPORTANT: With water supply inlet valve OPEN and water flow confirmed, turn on connected equipment. Failure to supply water to equipment may cause serious damage.

11. Record filter change on the service log.

system must be turned off prior to shutting off

system by closing Inlet Ball Valve.
