Equipment Specifications

Watts OneFlow systems are complete, self-contained, loaded
®
with media and ready to use. A simple inlet and outlet connec-
tion is all that is required for installation. Please review operat-
ing pressures, temperatures and water chemistry limitations to
ensure compatibility.

WARNING
!
*High levels of Copper will foul OneFlow media and typically
originates from new Copper plumbing. Wait a minimum of
4 weeks before placing system in operation. Avoid apply-
ing excess flux on the inner surfaces of the pipe and to use
a low-corrosivity water soluble flux listed under the ASTM
B813 standard.
NOTICE
** OneFlow media does not reduce silica scaling. Silica can act
as a binder that makes water spots and scale residue outside
the plumbing system difficult to remove. This 20 ppm limita-
tion is for aesthetic purposes.

Using OneFlow with other water treatment
®
equipment.
Due to the unique properties of OneFlow
unique requirements for using OneFlow
tion or other forms of water treatment.
1. OneFlow must be the last stage in the treatment chain. Do
®
not install any filters after OneFlow
which scale prevention is required. POU drinking water filters,
e.g. carbon or RO are exempt from this requirement.
2. Do not apply phosphate or any other antiscalant either before
or after OneFlow .
