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
system operates in an UP-Flow, fluidized bed mode, hav-
ing a level surface is more important than with a softener or
media filter.
• A bypass valve should be installed on every system to facili-
tate installation and service.
• Observe all local plumbing and building codes when install-
ing the system.
• 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 solder-
ing 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.
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 conventional
systems. Must be installed in VERTICAL POSITION.
• Because the OneFlow
®
system operates in the UP-flow
mode, the tank connections are opposite of traditional instal-
lations. Please follow water flow diagram illustrated in Figure
3.
• Please see the “Important note about iron, manganese and
copper in the water supply” section.
• Please see the note about “Using OneFlow
®
with other water
treatment equipment” on the previous page.
• This system is designed for residential applications only.
• This system comes with a bypass valve to bypass the sys-
tem 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.
Please see Figure 1 Bypass Valve and Connection Fittings
detail for proper assembly of the #CK-V3007. 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.
NOTICE
CAUTION
!
Iron and Manganese
NOTICE
*Iron and Manganese
Just as with conventional water softening media, OneFlow®
media needs to be protected from excess levels of certain metals
that can easily coat the active surface, reducing its effectiveness
over time. Public water supplies rarely, if ever, present a problem,
but if the water supply is from a private well, confirm that the levels
of iron (Fe) and manganese (Mn) are less than 0.3 mg/L and 0.05
mg/L, respectively.
Important notice about iron, manganese and copper in the
water supply
NOTICE
Copper
Pursuant to the EPA drinking water standards, the copper con-
centration permitted is up to 1.3 ppm. Typically originating from
new copper plumbing, high levels of copper can foul OneFlow
media. For applications with copper concentration greater than
1.3 ppm, please consult Watts Water Quality Technical Service.
To further minimize any problem with excess copper, avoid ap-
plying excessive flux on the inner surfaces of the pipe and use
a low-corrosivity water soluble flux listed under the ASTM B813
standard.
