CAUTION
!
Cautions!
• Not for use on closed loop systems.
• Do not let the system freeze. Damage to the tank may result.
• System must be operated in a vertical position. Do not lay
it down during operation. The system may be placed in any
position for shipping and installation but must be operated in
the vertical position.
• Place the system on a smooth, level surface. Because the sys-
tem operates in an UP-Flow, fluidized bed mode, having a level
surface is more important than with a softener or media filter.
• A bypass valve should be installed on every system to
facilitate installation and service.
• Observe all local plumbing and building codes when
installing the system.
• All new copper pipe and fittings used in the installation
of this system should be allowed to self passivate, under
normal operation and water flow, for a period of 4 weeks
minimum before placing the unit into service.
• Water known to have heavy loads of dirt and debris should
be prefiltered using a 20 micron filter cartridge model
number PWPL10FFM20 and 1" high flow filter housing kit
PWHIB10FF.
• If making a soldered copper installation, do all sweat soldering
before connecting pipes to the bypass valve. Torch heat will
damage plastic parts.
• When turning threaded pipe fittings onto plastic fittings, use
care not to cross-thread.
• Use PTFE tape on all external pipe threads. Do not use pipe
joint compound.
• Support inlet and outlet plumbing in some manner (use pipe
hangers) to keep the weight off of the bypass fittings.
• Do not use on water that is microbiologically unsafe or of
unknown quality.

NOTICE
Spotting May Occur on External Plumbing
Surfaces
OneFlow media systems perform best in single pass potable water
applications with NO additional chemical additives. Depending on
hardness, soft scale spotting may occur. Soft scale spots in most
cases can be easily wiped down with a damp cloth and will not
form hard scale deposits. A Point of Use (POU) Water Softener
should be used on mandatory spot-free applications (e.g. glass
stemware, dishware).
NOTICE
Notes to the Installer
The OneFlow system differs from a conventional softener or
media filter in a number of key respects.
• The system is light and only partially filled with media.
This is normal. The UP-flow operation of the system
requires a lot of freeboard to allow the bed to fully fluidize.
• The system has no underbed so you can tip the system
over without any fear of upsetting the media. This makes
transportation and installation much easier than conven-
tional systems. Must be installed in VERTICAL POSITION.
• Because the OneFlow system operates in the UP-flow
mode, the tank connections are opposite of traditional
installations. Please follow water flow diagram illustrated
in Figure 2.
• Please see the notices and warnings about "Feed Water
Chemistry Requirements and Operating Conditions" on
page 7.
• Please see the warning about "Using OneFlow with other
water treatment equipment" on page 4.
• This system is designed for residential applications only.
• This system comes with a bypass valve to bypass the
system in case of a leak or the need to remove the
system from the installation area. The nuts, locking rings,
and O-rings must be installed on the connection fittings
by the installer. To properly assemble the connection
fitting first install the nut, then install the locking ring in
the grove closest to the nut. Use care not to break the
locking ring. Finally install the O-ring in the grove at
the end of the fitting.
Note: Plumbing tape and general plumbing tools required.
