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 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, opera-
tion 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 install-
ing a fitting to avoid turning the valve.
• Do NOT install the unit behind equipment where it may be dif-
ficult 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
1. Turn off all equipment to be fed by the OneFlow ® System,
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 ® system on a wall stud or suitable mount-
ing material spanning wall studs. System must be vertical,
upright and level.
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 con-
necting 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 ® System.
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 of the OneFlow ® sys-
tem could be provided in 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 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.
12. Attach the Service Log to the installed OneFlow
® system and
fill in install date.
