Introduction
Your new OneFlow FoodService Filtration System will cleanse and
condition the tap water providing optimum water characteristics for
their specified applications. The result is reduced equipment
maintenance requirements, longer equipment life and improved
quality & consistency of your products. Proper system installation
and routine filter changes will ensure years of trouble-free operation and performance.
The OneFlow System is built with the finest and most advanced
materials and each system is quality inspected and pressure tested
prior to shipment. With proper installation and routine maintenance, you will have years of trouble-free operation.
Please refer to this manual when performing routine filter changes.
The instructions make periodic maintenance quick and easy, and
ensure you will receive maximum benefit from your system.
System Specifications
Maximum Pressure: 125 psi/8.6 bar
Maximum Temperature: 100°F/38°C, Min.: 35°F/2°C
Inlet/Outlet Connections: 1/2'' fnpt 1.5 & 3 gpm units
3/4'' fnpt 4 gpm units
Capacity: Change the DOR-OF110RC, DOR-OF120RC,
DOR-OF140RC cartridge at gallon rating or at least every 6 months
or when optional pressure gauge needle enters the red zone on the
outlet gauge while water is flowing through the filter system under
normal operating conditions. The OneFlow media cartridge does
not have a grain removal capacity, however, naturally occurring
organics present in the water will gradually degrade the
effectiveness of this cartridge.
Change the DOR-OF110RM, DOR-OF120RM, DOR-OF140RM
cartridge at least once a year.

DO NOT DISCARDTHISMANUAL AFTER INSTALLATION. THIS MANUAL CONTAINS IMPORTANT OPERATION, MAINTENANCE AND PRECAUTIONARY INFORMATION. PLEASE
PRESENT THISMANUALTO USER/OPERATOR/OWNER AFTER INSTALLATION.
IT IS STRONGLY ENCOURAGED THAT YOU READ THIS MANUAL BEFORE INSTALLING SYSTEM TO ENSURETHE BEST POSSIBLE INSTALLATION.
INSTALLATION MUST CONFORM TO ALL LOCALAND STATE PLUMBINGCODES AND REGULATIONS.
CONNECT SYSTEM TO COLD WATER SUPPLY ONLY. WATER TEMP. CANNOT EXCEED 100°F/38°C.
SYSTEM MUST BE INSTALLEDIN A VERTICAL AND UPRIGHTPOSITION.
ONEFLOW SYSTEMS MUST NOT BE USED IN CONJUNCTION WITH POLYPHOSPHATEOR ANYOTHER SCALE INHIBITOR.
DO NOT USE WITH WATERTHAT IS MICROBIOLOGICALLY UNSAFE OR OF UNKNOWNQUALITY WITHOUTADEQUATE DISINFECTION BEFORE OR AFTER THE SYSTEM.
FAILURE TO CHANGE CARTRIDGES PER RECOMMENDED INTERVALS WITH ONEFLOWREPLACEMENT CARTRIDGES MAY LEAD TO SYSTEMFAILUREAND PROPERTY DAMAGE.
Installation Precautions
• Do NOT install system on line pressure above 125 psi.
• Do NOT install the system backwardswiththe feed water line connectedto the outlet.
• Do NOT useliquidpipecompounds for fitting connections. USE a maximum two to three wraps of teflon tape.
• Do NOT solder plumbing connections attached to filterhousing or inlet valve. Inlet valveand filter housing will be damagedby high temperature.
Do NOT allowsystemto freeze. Turn off watersupplyto housing and drainhousing if temperaturefalls below32°F.
•
• Do NOT install system in directsunlightor where system is exposed to harsh chemicals or may be subjected to being struck by
moving equipment, carts, mops or any otheritem that may cause damage.
• ALLOW a minimum of 3'' underthe housingto allow for filter replacement.
• IF water hammer is evident, install water hammer arrestors before OneFlow unit.
• Do NOT overtighten fitting connections into inlet valve our 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 unit is always left to right; keep this in 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.

Installation Procedure
1.Turn off all equipment to be fed by the OneFlow, locate water supply cut-off valve
and turn off.
2.Determine if water line has an existing water treatment system. If so, examine
system for use of polyphospate or other scale inhibitors. OneFlow will not be
effective if used in conjunction with other scale inhibitors. Remove the scale
inhibitors from the water line or discontinue installation.
3.Install a 1/2'' full-flow ball valve on the water supply side that will feed the
water system.
4.Anchor the OneFlow on a wall stud or suitable mounting material spanning wall
studs. System must be vertical and upright.
5.Run a suitable line from the 1/2'' full-flow ball valve at 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 this line will be used to
facilitate flushing the system. As an option, a drain valve in a tee on the outlet side
Model OF-220-2
Capacity: 30,000 gals/113,600 L
Service Flow Rate: 3 gpm/11.3 lpm
Inlet/Outlet: 1/2'' FNPT
of the OneFlow could be provided in the line to facilitate flushing when
changing filters.
7.With System inlet valve closed, slowly open the 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 and any
carbon fines to escape. NOTE: NO ACTIVATION IS REQUIRED FOR THE
ONEFLOW SYSTEM TO PERFORM PROPERLY. FLUSHING IS
RECOMMENDED TO ALLOW AIR TO ESCAPE THE SYSTEM AND REMOVE
ANY CARBON FINES PRIOR TO CONNECTING TO EQUIPMENT.
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.
